block=&#8221;6&#8243;]<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"types-of-led-strip-chips\">Types of LED strip chips<\/h2>\n\n\n\n<p>If you\u2019re shopping for LED light strips, you\u2019re likely to come across all kinds of letter and number combinations that are supposed to describe the strip you\u2019re looking at. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"what-do-the-letters-mean\">What do the letters mean?<\/h3>\n\n\n\n<p>The letters in the description refer to the output color(s) of the LED chips on the strip.<\/p>\n\n\n\n<p>If the letters are separated by a &#8220;+&#8221; or a space, it usually means that they are separate chips. If there is no space, it usually means they are all integrated into one chip.<\/p>\n\n\n\n<p>When the LEDs are on separate chips, fewer lights can be packed into the same length strip.<\/p>\n\n\n\n<p><strong>RGB &#8211; Red, Green, Blue<\/strong><\/p>\n\n\n\n<p>An RGB LED contains three diodes (LED stands for Light Emitting Diode) on the same chip: one for each color. Each color is wired to its own channel. By adjusting the power delivered to each color (using a controller), any combination of colors can be created. <\/p>\n\n\n\n<p><strong>W &#8211; White<\/strong><\/p>\n\n\n\n<p>Typically a single &#8220;W&#8221; refers to a pure white (6500K). There&#8217;s no set standard so make sure to double check.<\/p>\n\n\n\n<p><strong>WW &#8211; Warm White<\/strong><\/p>\n\n\n\n<p>Warm white is usually 2700K, similar to the color of an incandescent bulb.<\/p>\n\n\n\n<p><strong>CW &#8211; Cold (or cool) White<\/strong><\/p>\n\n\n\n<p>Cold white is in the 6500K range, but check to be sure.<\/p>\n\n\n\n<p><strong>CCT &#8211; Color Correlated Temperature<\/strong><\/p>\n\n\n\n<p>CCT usually means that the strip includes two channels of white. One is a warm white and the other is a cool white. By adjusting the power delivered to each white channel, the strip can produce any white light equal to or in between the two LEDs. The CCT LEDs can either be both on the same chip or on separate chips.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"examples-of-common-led-chip-configurations\">Examples of common LED chip configurations:<\/h4>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td>Label<\/td><td>Description<\/td><\/tr><tr><td>RGB<\/td><td>A single 3 channel chip with RGB LEDs<\/td><\/tr><tr><td>RGBW<\/td><td>A single 4 channel chip with RGB and white LEDs<\/td><\/tr><tr><td>RGB+W<\/td><td>One 3 channel chip with RGB LEDs and a separate single channel chip with white LED<\/td><\/tr><tr><td>RGB+CCT<\/td><td>One 3 channel chip with RGB LEDs and a separate 2 channel chip with cold white and warm white LEDs<\/td><\/tr><tr><td>RGBCCT<\/td><td>A single 5 channel chip with RGB, CW, and WW LEDs<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<hr class=\"wp-block-separator has-css-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"what-do-the-numbers-mean\">What do the numbers mean?<\/h3>\n\n\n\n<p>An LED strip description often includes a 4-digit number such as 5050 or 2835. The number usually describes the <a href=\"https:\/\/www.instyleled.co.uk\/support\/what-are-the-differences-between-types-of-led-chip\/\" target=\"_blank\" rel=\"noreferrer noopener\">size<\/a> of the chip.<\/p>\n\n\n\n<p>For example, a 5050 LED chip measures 5.0 mm wide by 5.0 mm tall. Similarly, a 2835 chip measures 2.8 mm wide by 3.5 mm tall.<\/p>\n\n\n\n<p>If you are looking at a digitally addressable strip, you will likely see a four digit number (for example, WS2812B or SK6812). But in this case, it has nothing to do with chip size. Instead, the number is the name of the integrated LED controller chip.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/WS2812B-LED-Driver-IC-5050-RGB-LED-768x432-1.jpg\" alt=\"\" class=\"wp-image-4799\" width=\"580\" height=\"326\" srcset=\"https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/WS2812B-LED-Driver-IC-5050-RGB-LED-768x432-1.jpg 768w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/WS2812B-LED-Driver-IC-5050-RGB-LED-768x432-1-300x169.jpg 300w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/WS2812B-LED-Driver-IC-5050-RGB-LED-768x432-1-150x84.jpg 150w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/WS2812B-LED-Driver-IC-5050-RGB-LED-768x432-1-65x37.jpg 65w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/WS2812B-LED-Driver-IC-5050-RGB-LED-768x432-1-220x124.jpg 220w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/WS2812B-LED-Driver-IC-5050-RGB-LED-768x432-1-178x100.jpg 178w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/WS2812B-LED-Driver-IC-5050-RGB-LED-768x432-1-288x162.jpg 288w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/WS2812B-LED-Driver-IC-5050-RGB-LED-768x432-1-250x141.jpg 250w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/WS2812B-LED-Driver-IC-5050-RGB-LED-768x432-1-619x348.jpg 619w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/WS2812B-LED-Driver-IC-5050-RGB-LED-768x432-1-718x404.jpg 718w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/WS2812B-LED-Driver-IC-5050-RGB-LED-768x432-1-86x48.jpg 86w\" sizes=\"(max-width: 580px) 100vw, 580px\" \/><figcaption class=\"wp-element-caption\"><a href=\"https:\/\/howtomechatronics.com\/tutorials\/arduino\/how-to-control-ws2812b-individually-addressable-leds-using-arduino\/\" target=\"_blank\" rel=\"noreferrer noopener\">Source<\/a><\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td>Common addressable LED controllers:<\/td><\/tr><tr><td>WS2811<\/td><\/tr><tr><td>WS2812 ECO<\/td><\/tr><tr><td>WS2812B<\/td><\/tr><tr><td>WS2813<\/td><\/tr><tr><td><br>WS2815<\/td><\/tr><tr><td>SK6812<\/td><\/tr><tr><td>SK9822<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"does-size-matter\">Does size matter?<\/h4>\n\n\n\n<p>Although most equal sized chips have similar characteristics, not all chip manufacturers are created equal. Therefore, there&#8217;s no guarantee that chips of the same size from different manufacturers have similar performance.<\/p>\n\n\n\n<p>Generally a larger chip is brighter, but not necessarily. Ultimately, several factors determine the overall brightness including the chip circuit design, power consumed, and materials used. <\/p>\n\n\n\n<p>For example, below is a table with basic specifications for three different chips made by Epistar (a popular LED manufacturer). <\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td>LED<\/td><td>Chip Surface Area<\/td><td>Luminous Flux<\/td><td>Power consumed<\/td><\/tr><tr><td>2835<\/td><td>9.8 mm2<\/td><td>22-24 lm<\/td><td>0.2 W<\/td><\/tr><tr><td>5054<\/td><td>27 mm2<\/td><td>45-55<\/td><td>0.5 W<\/td><\/tr><tr><td>5630<\/td><td>16.8 mm2<\/td><td>50-60 lm<\/td><td>0.5 W<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>Notice how the 5630 puts out more light than the 5054 even though it has less surface area. Also, it manages to put out more light while still using the same amount of power (more efficient).<\/p>\n\n\n\n<p>Size <em>does<\/em> play a role in determining how many LEDs can be mounted on a strip:<\/p>\n\n\n\n<p>1. A narrow chip can be mounted to the strip more closely together creating a more uniform light.<\/p>\n\n\n\n<div class=\"inherit-container-width wp-block-group is-layout-constrained wp-block-group-is-layout-constrained\"><div class=\"wp-block-group__inner-container\">\n<p>2. A large chip can potentially fit multiple diodes on the same chip. This can allow for a better spacing for multi-purpose (color-changing) strips. <\/p>\n\n\n\n<p>For example, an RGBCCT chip has 5 total diodes on one chip. The same chip is used continuously throughout the strip. Each chip can create colors and whites. <\/p>\n\n\n\n<p>Compare that with an RGB+CCT strip. Two different chips are used. One creates colors and one creates whites. They are arranged alternately. <\/p>\n\n\n\n<p>The distance between each similarly colored LED is greater on the RGB+CCT strip compared to the RGBCCT strip. In practice, the bigger gap can make the light less uniform.<\/p>\n<\/div><\/div>\n\n\n\n<hr class=\"wp-block-separator has-css-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"how-to-choose-the-right-led-strip\">How to choose the right LED strip<\/h2>\n\n\n\n<p>There are seemingly endless variations of LED strips that are being sold in a wide price range. What are the differences between cheap and expensive? And, what is best for your project?<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"brightness\">Brightness<\/h3>\n\n\n\n<p>Brightness or luminosity is usually measured in lumens. For LED strips, the question you are interested in is, how bright is my strip per unit length?  So rather than a total lumen amount, you should be looking for lumens\/foot or lumens\/meter.<\/p>\n\n\n\n<p>Here are some guidelines for choosing a brightness level depending on the situation.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td>Use<\/td><td>Suggested Lumen\/foot<\/td><\/tr><tr><td>Accent\/Mood lighting<\/td><td>150-350<\/td><\/tr><tr><td>Under cabinet lighting<\/td><td>175-525<\/td><\/tr><tr><td>Task lighting (close)<\/td><td>275-450<\/td><\/tr><tr><td>Task lighting (far)<\/td><td>350-700<\/td><\/tr><tr><td>Indirect lighting<\/td><td>375-575<\/td><\/tr><tr><td>Fluorescent tube replacement<\/td><td>500-950<\/td><\/tr><\/tbody><\/table><figcaption class=\"wp-element-caption\"><a href=\"https:\/\/www.flexfireleds.com\/top-4-considerations-before-buying-flexible-led-strip-lights\/\" target=\"_blank\" rel=\"noreferrer noopener\">Source<\/a><\/figcaption><\/figure>\n\n\n\n<p>It&#8217;s a good idea to buy strips with extra brightness for your application. Then, get a dimmer to reduce the brightness to the desired level. <\/p>\n\n\n\n<p>Using a dimmer will lower the operating temperature of the LEDs which will lengthen their lifespan. <\/p>\n\n\n\n<p>Furthermore, as LEDs age, they do lose some of their luminosity. If you oversize your LEDs a bit from the beginning, you will have some extra brightness to make up the difference as they age. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"efficiency\">Efficiency<\/h3>\n\n\n\n<p>Luminosity doesn&#8217;t always tell the full story. You can get more brightness out of any LED if you pump enough power through it, but that&#8217;s not always a good thing.<\/p>\n\n\n\n<p>An LED strip manufacturer can increase the reported lumen output by overpowering the LEDs. This will cause them to shine more brightly, but will also cause them to get hotter and run less efficiently. Since heat is the main reason for an LED to fail prematurely, it&#8217;s likely that overpowered LEDs will not last as long as they otherwise could.<\/p>\n\n\n\n<p>For that reason, it&#8217;s good to ask the question, how much light does it put out compared to power used? This ratio is called the <a rel=\"noreferrer noopener\" href=\"https:\/\/en.wikipedia.org\/wiki\/Luminous_efficacy\" target=\"_blank\">luminous efficacy<\/a>. It&#8217;s often listed in a products specs. If not, you can calculate the efficacy by dividing the number of lumens produced by how much power it uses. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"do-i-need-a-high-cri-light\">Do I <em>need<\/em> a high CRI light?<\/h3>\n\n\n\n<p>Color rendering index (CRI) is a measure of how accurately an artificial light source replicates natural light. It is reported as a number from 0-100.<\/p>\n\n\n\n<p>A CRI greater than 80 is acceptable for most applications.<\/p>\n\n\n\n<p>A CRI greater than 90 is considered high CRI and is mainly used in retail, art, film, or photography. Some of the best quality LED strips have a CRI of 97-99.<\/p>\n\n\n\n<p><strong>Why is CRI important?<\/strong><\/p>\n\n\n\n<p>Objects under low CRI lighting may seem dull or harsh depending on the light and color. Colors will be less vibrant and the overall lighting effect will seem less bright.<\/p>\n\n\n\n<p>But why is that? <\/p>\n\n\n\n<p class=\"has-very-light-gray-background-color has-background\">NOTE: What follows is a technical explanation of what makes a high CRI light. You can skip it if nerdy stuff makes your eyes glaze over.<\/p>\n\n\n\n<p>Light that we can see is usually not made up of a single wavelength. Rather, it&#8217;s a collection of waves that span the visible spectrum.

Generally, 12V is perfect for small installations, but for large installations, it may be better to go with 24V.<\/p>\n\n\n\n<p>For projects with digital strips, it can sometimes be convenient to use 5V strips. Most digital controllers run on 5V which allows the controller and the strips to be run from the same power supply. Furthermore, on 5V strips each individual LED can be independently controlled.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"higher-voltage-means-longer-runs\">Higher voltage means longer runs<\/h4>\n\n\n\n<p>A higher voltage strip will generally be able to have longer runs without suffering from the effects of voltage drop.<\/p>\n\n\n\n<p><strong>What is voltage drop?<\/strong><\/p>\n\n\n\n<p>Voltage drop causes LED strips to lose their intensity as the strip becomes longer. LEDs at the beginning of the strip (nearest the power supply) will shine brightly. Whereas, LEDs at the end of the strip will have a dimmed appearance. <\/p>\n\n\n\n<p><strong>An example of voltage drop<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"http:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/DSC05694-1024x683.jpg\" alt=\"\" class=\"wp-image-4823\" srcset=\"https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/DSC05694-1024x683.jpg 1024w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/DSC05694-300x200.jpg 300w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/DSC05694-150x100.jpg 150w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/DSC05694-768x512.jpg 768w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/DSC05694-1536x1024.jpg 1536w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/DSC05694-2048x1365.jpg 2048w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/DSC05694-65x43.jpg 65w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/DSC05694-220x147.jpg 220w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/DSC05694-243x162.jpg 243w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/DSC05694-240x160.jpg 240w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/DSC05694-522x348.jpg 522w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/DSC05694-606x404.jpg 606w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/DSC05694-780x520.jpg 780w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/DSC05694-86x57.jpg 86w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/DSC05694-scaled.jpg 924w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>Above is a great example of the effects of voltage drop. <\/p>\n\n\n\n<p>A couple years ago, I installed some indirect lighting in my living room. I used 12V strips and made a loop around the perimeter of the room by connecting three 5m strips end to end to one power source.<\/p>\n\n\n\n<p>The bright light on the left is the start of the strips. The lights travel around the room and end right next to the beginning. The lights on the right side are suffering from voltage drop and are much less bright.<\/p>\n\n\n\n<p><strong>Why does this happen?<\/strong><\/p>\n\n\n\n<p>Any length of wire has a certain amount of electrical resistance. The longer the wire, the more the resistance. Electrical resistance causes voltage drop and voltage drop causes your LEDs to dim. <\/p>\n\n\n\n<p>Therefore, LEDs at the end of a strip will always be getting less voltage than the LEDs at the beginning. If you make the strip long enough, the drop in voltage will become significant enough to cause a visible difference in brightness.<\/p>\n\n\n\n<p><strong>How does higher voltage reduce the effects of voltage drop?<\/strong><\/p>\n\n\n\n<p>First, you have to have a basic understanding of how all the components on an LED strip are connected. <\/p>\n\n\n\n<p>Most individual LED chips run on 3V DC power regardless of whether they are mounted on a 12V strip or a 24V strip. In fact, the same LED chip that works on a 12V strip could also be mounted on a 24V strip. What makes the difference is how the strip circuitry is designed.<\/p>\n\n\n\n<p>LED chips are wired in series into groups. Each group contains some LED chips and a resistor. The total voltage drop across the group has to be equal to the total voltage of the strip (see diagrams below). <\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/12v-led-chip-voltage.png\" alt=\"\" class=\"wp-image-4826\" width=\"368\" height=\"127\" srcset=\"https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/12v-led-chip-voltage.png 712w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/12v-led-chip-voltage-300x104.png 300w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/12v-led-chip-voltage-150x52.png 150w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/12v-led-chip-voltage-65x23.png 65w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/12v-led-chip-voltage-220x76.png 220w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/12v-led-chip-voltage-250x87.png 250w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/12v-led-chip-voltage-467x162.png 467w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/12v-led-chip-voltage-696x241.png 696w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/12v-led-chip-voltage-86x30.png 86w\" sizes=\"(max-width: 368px) 100vw, 368px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"216\" src=\"http:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/24v-led-chip-voltage-1-1024x216.png\" alt=\"\" class=\"wp-image-4828\" srcset=\"https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/24v-led-chip-voltage-1-1024x216.png 1024w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/24v-led-chip-voltage-1-300x63.png 300w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/24v-led-chip-voltage-1-150x32.png 150w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/24v-led-chip-voltage-1-768x162.png 768w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/24v-led-chip-voltage-1-65x14.png 65w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/24v-led-chip-voltage-1-220x46.png 220w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/24v-led-chip-voltage-1-250x53.png 250w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/24v-led-chip-voltage-1-510x108.png 510w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/24v-led-chip-voltage-1-696x147.png 696w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/24v-led-chip-voltage-1-807x171.png 807w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/24v-led-chip-voltage-1-1040x220.png 1040w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/24v-led-chip-voltage-1-86x18.png 86w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/24v-led-chip-voltage-1.png 924w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>Then, each of the groups is wired in parallel and arranged along the length of the strip.<\/p>\n\n\n\n<p>For now, take notice (above diagrams) that the group size on a 24V strip is 7 LEDs compared to only 3 LEDs for 12V. I will explain why this is significant below.<\/p>\n\n\n\n<p>Every wire has a certain amount of resistance to electricity being pushed through it.

Therefore, the smaller each group of LEDs, the closer together the cut lines can be.<\/p>\n\n\n\n<p>For example, see the diagrams of 12V and 24V strips below. <\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"254\" src=\"http:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/led-groups-2-1024x254.png\" alt=\"\" class=\"wp-image-4821\" srcset=\"https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/led-groups-2-1024x254.png 1024w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/led-groups-2-300x74.png 300w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/led-groups-2-150x37.png 150w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/led-groups-2-768x191.png 768w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/led-groups-2-65x16.png 65w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/led-groups-2-220x55.png 220w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/led-groups-2-250x62.png 250w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/led-groups-2-510x127.png 510w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/led-groups-2-696x173.png 696w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/led-groups-2-807x200.png 807w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/led-groups-2-1040x258.png 1040w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/led-groups-2-86x21.png 86w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/led-groups-2.png 924w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"201\" src=\"http:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/24v-led-1024x201.png\" alt=\"\" class=\"wp-image-4825\" srcset=\"https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/24v-led-1024x201.png 1024w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/24v-led-300x59.png 300w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/24v-led-150x29.png 150w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/24v-led-768x151.png 768w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/24v-led-65x13.png 65w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/24v-led-220x43.png 220w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/24v-led-250x49.png 250w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/24v-led-510x100.png 510w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/24v-led-696x136.png 696w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/24v-led-807x158.png 807w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/24v-led-1040x204.png 1040w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/24v-led-86x17.png 86w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/24v-led.png 924w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>If your installation has many corners with short lengths between, a lower voltage strip with closer cut lines may be a good choice. This can help to minimize the &#8220;dead&#8221; spots at the corners.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"higher-voltage-can-be-more-efficient\">Higher voltage can be more efficient<\/h4>\n\n\n\n<p>Any time there is voltage across a resistor, it means energy is getting converted to heat instead of light. Therefore, the resistors in the above diagrams are necessary, but they&#8217;re also a source of wasted energy. <\/p>\n\n\n\n<p><strong>How much is wasted?<\/strong><\/p>\n\n\n\n<p>The calculation is fairly simple. All we have to do is divide the amount of voltage across the resistor by the total voltage:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td>Total voltage of strip<\/td><td>Voltage across resistor<\/td><td>% Power &#8220;wasted&#8221; on resistors<\/td><\/tr><tr><td>5V<\/td><td>2V<\/td><td>40%<\/td><\/tr><tr><td>12V<\/td><td>3V<\/td><td>25%<\/td><\/tr><tr><td>24V<\/td><td>3V<\/td><td>12.5%<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>It&#8217;s easy to see that higher voltage strips suffer from less wasted energy. LED&#8217;s use such a small amount of energy that this doesn&#8217;t add up to much for small installations. But, for whole room or commercial installations, the difference in power usage can become significant.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-css-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"how-thick-is-the-copper\">How thick is the copper?<\/h3>\n\n\n\n<p>The flexible strip that the LEDs are mounted on is actually a circuit board. Within the strip, there is a layer of copper that provides the electrical circuitry and the bulk of the heat dissipation.<\/p>\n\n\n\n<p>For those reasons, the thickness of the copper layer matters. <\/p>\n\n\n\n<p>A thicker layer of copper means electricity can flow through more easily (less electrical resistance). This will create less voltage drop and allow longer runs. <\/p>\n\n\n\n<p>It will also dissipate heat more quickly. The LEDs will stay cooler, which will ultimately help to maximize their lifespan. <\/p>\n\n\n\n<p>The amount of copper in an LED strip is usually measured in ounces per square foot. Typical values for an LED strip are 1oz-4oz. Higher power requires more copper.<\/p>\n\n\n\n<p>Unfortunately, very few retailers list this on the product info page. If you&#8217;re planning a small project with some bargain level strips, I wouldn&#8217;t worry too much about it. <\/p>\n\n\n\n<p>However, if you are planning a big project with high-quality strips, it would be worth contacting the manufacturer if it isn&#8217;t listed on the specs page.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-css-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"how-to-install-led-strips\">How to install LED strips<\/h2>\n\n\n\n<p>The best way I&#8217;ve found to install LED strips is within an aluminum channel. <\/p>\n\n\n\n<p>The channels are available either angled or flat, and with a diffuser cover or clear cover. They do come in different widths, so make sure the channel fits the strip.<\/p>\n\n\n\n<p>You can cut the soft aluminum channels with a hacksaw or with an electric miter saw. If you use the miter saw, you should use a carbide tipped blade with lots of teeth.<\/p>\n\n\n\n<p>Once cut to length, the channel can be firmly mounted using screws. <\/p>\n\n\n\n<p>Benefits of installing LED strips inside a channel:<\/p>\n\n\n\n<ol>\n<li>Provides a uniform surface for the strip&#8217;s adhesive to form a secure, long-lasting bond. <\/li>\n\n\n\n<li>The aluminum acts as a heatsink and helps to dissipate heat for longer LED life.<\/li>\n\n\n\n<li>The plastic cover will diffuse the light. This will make the light from the LEDs appear more uniform. <\/li>\n\n\n\n<li>The cover will also help to protect the strip from dust and damage.<\/li>\n\n\n\n<li>If the LED strips are in plain view, the clean lines of the channels help to give the installation a more polished look.<\/li>\n<\/ol>\n\n\n\n<p>Despite all the great benefits of the channel, there are installations where the extra cost of the channels just isn&#8217;t worth it. <\/p>\n\n\n\n<p>The biggest problem you&#8217;ll have when installing without a channel is the strip&#8217;s adhesive not holding. It will usually stick initally. But sometimes a week or a month later, the adhesive will fail. <\/p>\n\n\n\n<p>In order to make sure the adhesive doesn&#8217;t work its way loose, I recommend using a dab of hot glue every couple feet.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"how-to-connect-led-strips\">How to connect LED strips<\/h3>\n\n\n\n<p>Soldering is usually the most reliable method for joining two LED strips. But, it&#8217;s also time consuming, requires special equipment, and requires a bit of skill.<\/p>\n\n\n\n<p>Clips are faster and don&#8217;t require any skill. For that reason, I recommend using clips if you&#8217;ll have easy access to the strips (most installations).<\/p>\n\n\n\n<p>However, the connections made by the clips are <a href=\"https:\/\/hitlights.com\/blogs\/news\/when-and-when-not-to-use-strip-to-strip-connectors\" target=\"_blank\" rel=\"noreferrer noopener\">not as permanent<\/a> as solder. They are vulnerable to corrosion and movement.<\/p>\n\n\n\n<p>Therefore, I recommend using solder if the strips may experience:<\/p>\n\n\n\n<ol>\n<li>Weather &#8211; any outdoor installation, or heating and cooling that could cause condensation<\/li>\n\n\n\n<li>Movement &#8211; any sort of flexible channel or location that might experience vibration<\/li>\n\n\n\n<li>Very permanent &#8211; enclosed in epoxy or other similar <\/li>\n<\/ol>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"how-to-deal-with-corners\">How to deal with corners<\/h3>\n\n\n\n<p>The challenge with corners is to effectively turn the corner without leaving a &#8220;light gap&#8221; and without spending too much time fiddling with cutting and connecting. <\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"gentle-bend\">Gentle bend<\/h4>\n\n\n\n<p>The best way I&#8217;ve found for most of my installations is just to create a gentle bend around the corner.<\/p>\n\n\n\n<p>For this method, you don&#8217;t need to cut the strip or have any special connecting hardware. You can do bends even if strip components happen to land right on the corner.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.birddogdistributing.com\/content\/blog_images\/uploads\/2016\/05\/image021.jpg\" alt=\"\"\/><figcaption class=\"wp-element-caption\"><a href=\"https:\/\/www.birddogdistributing.com\/blog\/turn-corner-led-strip-lights\" target=\"_blank\" rel=\"noreferrer noopener\">Source<\/a><\/figcaption><\/figure>\n\n\n\n<p>Guide the strip around the corner and let the strip take its own shape. The result will be a small loop in the corner. <\/p>\n\n\n\n<p>One problem with this method is over time the adhesive in the corner can be pulled up. To stop that from happening, use some hot glue on each side of the corner.<\/p>\n\n\n\n<p>If you are installing the strips inside a channel, the bent area may not fit inside. This is especially true for strips with densely packed components. In that case, I recommend cutting the strip and using the corner connectors instead.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"corner-connector\">Corner Connector<\/h4>\n\n\n\n<p>You can also cut the strips at the corners and rejoin them with connectors. However, LED strips must be cut on their cut lines. Therefore if the gap between cut lines is large, you could end up having a small gap with no light in the corner. <\/p>\n\n\n\n<p>This is an instance where installing the strips in a channel with a diffuser will be helpful. Without the diffuser, you will likely have a dim or dark spot.<\/p>\n\n\n\n<p>You can buy rigid plastic 90 degree corner connectors, but I recommend the type with wires. The flexible wires can be adjusted to any angle.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.birddogdistributing.com\/content\/blog_images\/uploads\/2016\/05\/image020.jpg\" alt=\"\"\/><figcaption class=\"wp-element-caption\"><a href=\"https:\/\/www.birddogdistributing.com\/blog\/turn-corner-led-strip-lights\" target=\"_blank\" rel=\"noreferrer noopener\">Source<\/a><\/figcaption><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"fold-method\">Fold Method<\/h4>\n\n\n\n<p>You <em>can<\/em> try to fold the strips but I don&#8217;t recommend it. The PCBs on most LED strips are quite flexible. Make sure your bend will not put any stress on areas with any components. Low density single color strips work the best for folding because there&#8217;s more &#8220;clean&#8221; area available for a fold. <\/p>\n\n\n\n<p>First, bend the strip at a right angle in the <em>opposite<\/em> direction of the turn.<\/p>\n\n\n\n<p>Then, make a second bend by folding the bent end back over itself.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"remove-led-strips\">Remove LED strips<\/h3>\n\n\n\n<p>Once an LED strip is securely stuck to a surface, it can seem nearly impossible to remove it without destroying the strip.<\/p>\n\n\n\n<p>Don&#8217;t just pull the strip and hope for the best. You will risk tearing the strip or damaging individual LED connections.<\/p>\n\n\n\n<p>Instead, use floss.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/media.giphy.com\/media\/3op5Txe6mc36sGbwOs\/giphy.gif\" alt=\"\" width=\"240\" height=\"240\"\/><\/figure>\n\n\n\n<p>No, not that kind of floss! Dental floss. <\/p>\n\n\n\n<p>Cut a length of floss and slide it under an edge. Then, work it back and forth along the length of the strip.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-css-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"how-to-power-led-strips\">How to power LED strips<\/h2>\n\n\n\n<p>LED chips are powered using DC (direct current). Therefore, you can&#8217;t plug an LED strip directly into the wall outlet (alternating current). Instead, you need a power supply to convert the AC power from the wall into DC power that the LED can use.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"how-to-select-an-led-power-supply\">How to Select an LED Power Supply<\/h3>\n\n\n\n<p>This is an area that often gets overlooked especially among hobbyists. If you&#8217;re going to spend money, you probably want to spend it on some super bright, high-quality LEDs. Therefore, it&#8217;s tempting to cheap out on a power supply. But, spending the money up front on a good power supply will often pay for itself over time.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"how-much-power-do-you-need\">How much power do you need?<\/h4>\n\n\n\n<p>First, you need to know how much power your strips will use so that you can select a properly sized power supply.<\/p>\n\n\n\n<p>Every vendor should list the power consumption of their LED strips. It may be listed as the power consumption of an individual LED chip or as the power per length of strip. Either way, just multiply the power per unit length by the total length of the strip you plan to use. That number will definitely be enough. However, in some cases it may actually be way too much due to how controllers manage your LEDs (<a href=\"https:\/\/thesmartcave.com\/how-much-power-do-led-strip-lights-use\/\">this post explains more<\/a>).<\/p>\n\n\n\n<p>Don&#8217;t worry, it&#8217;s not necessary to get a perfectly accurate number. Close is good enough.<\/p>\n\n\n\n<p>Once you have an estimate of the power usage of your strip, a good rule of thumb is to add another 20% (strip power \/ 0.8). Then, select a power supply that can provide greater than or equal to that amount. <\/p>\n\n\n\n<p>The extra capacity will help to insure a long life for the power supply. As with LEDs, a common cause of power supply failure is heat. And running a power supply at full capacity will heat it up.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"power-supply-voltage-must-match-the-leds\">Power supply voltage must match the LEDs<\/h4>\n\n\n\n<p>The power supply <strong>must<\/strong> be the same voltage as the LED strip.<\/p>\n\n\n\n<p>For example, if you try to use a 24V power supply on a 12V strip, the LEDs will shine very brightly (overpowered) for a short period of time. Before long, they will overheat and burn out.<\/p>\n\n\n\n<p>Conversely, if you try to use a 12V power supply on a 24V strip, the underpowered LEDs will not light up at all.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"waterproof-or-not\">Waterproof or not? <\/h4>\n\n\n\n<p>A power supply enclosure is usually rated using the <a rel=\"noreferrer noopener\" href=\"https:\/\/en.wikipedia.org\/wiki\/IP_Code\" target=\"_blank\">IP rating system<\/a>. The first number of the IP rating is protection against sold objects (e.g. fingers, dirt, dust). The second number is protection against liquid (e.g. dripping, spraying, immersion).<\/p>\n\n\n\n<p><strong>Waterproofing<\/strong><\/p>\n\n\n\n<p>If you&#8217;re looking for a waterproof power supply, I recommend making sure you get an IP67 or IP68. These are expected to be fully submersible. <\/p>\n\n\n\n<p>You can also find power supplies with an IP65 rating marketed as waterproof. These are protected against water spray (e.g. heavy downpour, hose spray nozzle) but not submersion. <\/p>\n\n\n\n<p>The price difference between IP65 and IP67-68 is usually minor, so the extra protection is worth it.<\/p>\n\n\n\n<p><strong>Dustproofing<\/strong><\/p>\n\n\n\n<p>Even if you&#8217;re not worried about water, you may want a sealed power supply to protect against dust.<\/p>\n\n\n\n<p>Any power supply with an IP rating that starts with &#8220;IP6&#8221; will be sealed against dust. <\/p>\n\n\n\n<p>If power supplies are open to the air, dust can accumulate on internal components. This contributes to excess heat build up which can shorten the life of the power supply.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"power-supply-efficiency\">Power supply efficiency<\/h4>\n\n\n\n<p>The efficiency of your power supply can make a big difference in total power usage. Typical efficiencies for power supplies run between 70% and 90%.<\/p>\n\n\n\n<p>For example:<\/p>\n\n\n\n<p>If I have an LED strip that uses 100W, a power supply with 70% efficiency will draw 100W\/0.70 = <span style=\"text-decoration: underline;\">143W<\/span> of electricity.<\/p>\n\n\n\n<p>Whereas a power supply with 90% efficiency will only draw 100W\/0.90 = <span style=\"text-decoration: underline;\">111W<\/span>.<\/p>\n\n\n\n<p>For the most part, if you want more efficiency from your power supply, you have to pay for it. Whether or not it makes sense to pay for more efficiency will usually depend on the size of your project.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"installing-the-power-supply\">Installing the power supply<\/h3>\n\n\n\n<p>If you plan to just plug your LED power into an existing outlet, you don&#8217;t need to worry about violating building codes. As long as you&#8217;re not tapping into mains voltage or running wires inside walls, you are in the clear.<\/p>\n\n\n\n<p>However, if you&#8217;re doing a large installation, you probably don&#8217;t want wires hanging around everywhere. In that case, a clean install usually requires multiple LED driver power supplies and running wires through walls.<\/p>\n\n\n\n<p>If you&#8217;d like to have a nice, clean look, consider putting all the power supplies inside an enclosure. Bring the line voltage into the enclosure and wire up an outlet within the enclosure. Then mount the power supplies and plug them into the outlet.<\/p>\n\n\n\n<p><strong>DO<\/strong> buy a class 2 rated power supply. If you are running wires within walls, this will make sure you don&#8217;t exceed power requirements. A class 2 power supply is limited to 60W for 12V and 96W for 24V. <\/p>\n\n\n\n<p>A single power supply can exceed the power limit if it <a href=\"https:\/\/www.elementalled.com\/low-voltage-safety-understanding-class-2-compliance\/\" target=\"_blank\" rel=\"noreferrer noopener\">splits the power<\/a> into multiple outputs as long as each output is within the power limits.<\/p>\n\n\n\n<p><strong>DO<\/strong> use class 2 compliant (CL2) wiring if you will be installing any wires inside finished walls.<\/p>\n\n\n\n<p><strong>DONT<\/strong> wire your power supply directly to line voltage. Instead, connect a 3 prong plug to the input (120V) side and plug it into an outlet.<\/p>\n\n\n\n<p><strong>DONT<\/strong> install the power supply inside a wall without an access panel. This should go without saying, but there&#8217;s always <em>that guy<\/em>. Power supplies do fail and if they&#8217;re stuck inside the wall, it becomes quite a maintenance headache.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"how-to-power-very-long-strips\">How to power very long strips<\/h3>\n\n\n\n<p>If you have a long enough run of LED strips, you will experience voltage drop. You can reduce this problem by using higher voltage strips (as explained above), but that won&#8217;t solve the problem completely. Eventually, if the run is long enough, even a 24V strip will suffer the effects of voltage drop. <\/p>\n\n\n\n<p>Fortunately, there are ways to extend the reach of your strips without too much trouble.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"install-the-power-supply-in-the-middle\"><strong>Install the power supply in the middle<\/strong><\/h4>\n\n\n\n<p>The simplest way to double the effective length of your strips is to place the power in the middle of two strips. Similarly, if the strip makes a loop, you can connect both ends to the power.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"512\" src=\"http:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/split-power-2-1024x512.png\" alt=\"\" class=\"wp-image-4843\" srcset=\"https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/split-power-2-1024x512.png 1024w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/split-power-2-300x150.png 300w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/split-power-2-150x75.png 150w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/split-power-2-768x384.png 768w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/split-power-2-65x33.png 65w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/split-power-2-220x110.png 220w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/split-power-2-200x100.png 200w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/split-power-2-324x162.png 324w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/split-power-2-250x125.png 250w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/split-power-2-696x348.png 696w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/split-power-2-807x404.png 807w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/split-power-2-1040x520.png 1040w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/split-power-2-86x43.png 86w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/split-power-2.png 1178w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"use-power-injection\">Use power injection<\/h4>\n\n\n\n<p>Of course, sometimes you&#8217;ll be limited by where you can install your power supply. In other cases, you will have such a long run of lights that even placing the power in the center won&#8217;t be enough to avoid the voltage drop.<\/p>\n\n\n\n<p>In those cases, you will have to run more wires to the locations that need it. This is called power injection. <\/p>\n\n\n\n<p>Power injection can be done with one power supply or multiple power supplies. It&#8217;s done differently for analog and digital strips.<\/p>\n\n\n\n<p><strong><span style=\"text-decoration: underline;\">Power injection for analog LED strips<\/span><\/strong><\/p>\n\n\n\n<p>Analog strips don&#8217;t have embedded microcontrollers like the digital strips. That means that some kind of voltage controller needs to be installed between the power supply and the strip at <em>all<\/em> connections.<\/p>\n\n\n\n<p>One option would be to buy a second controller. Essentially that would create a second LED strip with separate power and separate control. Then if you wanted to, you could use automation software to make sure the two controllers stay synchronized.<\/p>\n\n\n\n<p>However, there&#8217;s a simpler (and cheaper) solution. <\/p>\n\n\n\n<p><strong>Signal Repeaters<\/strong><\/p>\n\n\n\n<p>A signal repeater can be connected anywhere that power injection is needed. The repeater will transfer the signal so that all LEDs are synchronized by a single controller. <\/p>\n\n\n\n<p>This way is simpler for home automation because only the one controller is added to the smart home network.<\/p>\n\n\n\n<p>It also makes the wiring for power injection simple. All you need to do is connect power to the repeater and wire the two strips to the repeater.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"924\" height=\"399\" src=\"http:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/power-injection-for-analog-LED-strips-with-one-power-supply.png\" alt=\"\" class=\"wp-image-4849\" srcset=\"https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/power-injection-for-analog-LED-strips-with-one-power-supply.png 924w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/power-injection-for-analog-LED-strips-with-one-power-supply-300x130.png 300w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/power-injection-for-analog-LED-strips-with-one-power-supply-150x65.png 150w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/power-injection-for-analog-LED-strips-with-one-power-supply-768x332.png 768w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/power-injection-for-analog-LED-strips-with-one-power-supply-65x28.png 65w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/power-injection-for-analog-LED-strips-with-one-power-supply-220x95.png 220w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/power-injection-for-analog-LED-strips-with-one-power-supply-231x100.png 231w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/power-injection-for-analog-LED-strips-with-one-power-supply-375x162.png 375w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/power-injection-for-analog-LED-strips-with-one-power-supply-250x108.png 250w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/power-injection-for-analog-LED-strips-with-one-power-supply-696x301.png 696w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/power-injection-for-analog-LED-strips-with-one-power-supply-807x349.png 807w, https:\/\/thesmartcave.com\/wp-content\/uploads\/2020\/04\/power-injection-for-analog-LED-strips-with-one-power-supply-86x37.png 86w\" sizes=\"(max-width: 924px) 100vw, 924px\" \/><\/figure>\n\n\n\n<p>A repeater can be powered from the same power supply as the controller (above).

You could just connect it directly to a power supply. <\/p>\n\n\n\n<p>Then, if you wanted to turn it into a smart light, you could plug the power supply into a <a href=\"http:\/\/thesmartcave.com\/tp-link-smart-plug-bulb-review\/\">smart plug<\/a>. It works, but it&#8217;s very basic.<\/p>\n\n\n\n<p>However, even if you don&#8217;t care about changing colors, most people will at least want the ability to dim. And in order to do that, you will need a controller.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"how-to-dim-led-strips\">How to dim LED strips<\/h3>\n\n\n\n<p>There are two common ways to dim LED strips using smart control.<\/p>\n\n\n\n<p>The first way is to use a smart AC dimmer installed in the wall. In order to do this, the wiring goes from the dimmer switch to the power supply to the lights. <\/p>\n\n\n\n<p><span style=\"text-decoration: underline;\">Pros\/Cons of this method:<\/span><br><strong>Con<\/strong> &#8211; You must have a dimmable power supply for this to work. These are usually more expensive than regular power supplies.<br><strong>Pro<\/strong> &#8211; You can use any standard dimmer including smart dimmers like the <a href=\"http:\/\/thesmartcave.com\/lutron-caseta-review\/\">Lutron Caseta dimmers<\/a>.<br><strong>Pro<\/strong> &#8211; When the lights are turned off, the power supply is turned off. This eliminates a source of &#8220;vampire&#8221; power.<br><strong>Con<\/strong> &#8211; Only works with single color LED strips.<\/p>\n\n\n\n<p>A second way is to use a smart controller. Here, the wiring goes from the power supply to the controller to the lights. <\/p>\n\n\n\n<p><span style=\"text-decoration: underline;\">Pros\/Cons of this method:<\/span><\/p>\n\n\n\n<p><strong>Pro<\/strong> &#8211; Smart controllers can control strips with multiple colors.<br><strong>Pro<\/strong> &#8211; Doesn&#8217;t require a dimmable power supply.<br><strong>Con<\/strong> &#8211; The lights are not wired directly to a wall control. In order to have control at the wall, it would require installing one of these <a href=\"http:\/\/thesmartcave.com\/smart-switch-with-smart-bulb\/\">extra smart switches<\/a> at the desired location to communicate with the LED controller.<br><strong>Con<\/strong> &#8211; The power supply is always on resulting in a source of vampire power.<\/p>\n\n\n\n<p>This second method is my preferred way to do it. I&#8217;m a huge fan of color changing lights. Even if it&#8217;s in an area where I don&#8217;t need full color, I still want the ability to do white color shifting. I&#8217;m a big believer in using <a href=\"http:\/\/thesmartcave.com\/circadian-lighting-smart-bulbs\/\">circadian lighting<\/a> whenever possible.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"how-to-control-led-strip-color\">How to control LED strip color<\/h3>\n\n\n\n<p>If your LED strips are color changing strips, you will need a smart controller.<\/p>\n\n\n\n<p>Make sure your controller has enough channels. If you have an RGBW strip, you need a controller with 5 output terminals. One terminal is the supply voltage (V+). The other four terminals are for each of the R, G, B, and W LEDs.<\/p>\n\n\n\n<p>It&#8217;s okay to use a controller with too many channels. However, be aware that there is a limit to how much current can run on each channel.<\/p>\n\n\n\n<p>A controller has a limit to how much current can be ran through it. For example, this RGBGenie controller can handle up to x amps.<\/p>\n\n\n\n<p>In most cases, voltage drop will cause problems long before your controller runs out of capacity.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"wireless-protocols\">Wireless protocols <\/h3>\n\n\n\n<p>A smart LED controller communicates with your smart home using some kind of wireless &#8220;language&#8221; (protocol). You have basically three protocols to choose from: WiFi, Zigbee, or Z-Wave.<\/p>\n\n\n\n<p>If you don&#8217;t have any other smart home stuff, I recommend sticking with a WiFi controller. It doesn&#8217;t require an additional hub (uses your WiFi router) and tends to be cheaper than the other two options.. <\/p>\n\n\n\n<p><a href=\"http:\/\/thesmartcave.com\/z-wave-vs-zigbee-home-automation\/\">Zigbee and Z-Wave<\/a> are both wireless protocols designed specifically for home automation. With one of these controllers, you can connect your controller to a smart hub like Samsung SmartThings and your automation possibilities will be endless.<\/p>\n\n\n\n<p>I prefer the Zigbee protocol for my lights because it works with the Philips Hue hub. The Hue hub is very reliable and has super fast reaction times. Plus, I already have a bunch of Philips Hue lights so my Hue mesh network is strong. <\/p>\n\n\n\n<p>NOTE: If you want your controller to be compatible with Hue, you have to make sure it&#8217;s a Zigbee 3.0 certified controller.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"where-to-install-the-controller\">Where to install the controller<\/h3>\n\n\n\n<p>Controllers are usually much smaller than power supplies so they are easier to hide.<\/p>\n\n\n\n<p>In most installations, it makes sense to install the controller as close to the strips as possible.<\/p>\n\n\n\n<p>If necessary, run heavy gauge wire from the power supply to the controller to minimize voltage drop. Then switch to lighter gauge wire from the controller to the strips.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"how-to-control-digital-addressable-led-strips\">How to control individually addressable LED strips<\/h3>\n\n\n\n<p>For analog strips, all LEDs of the same color are wired to a single channel. A single controller can adjust the power to each channel independently, but cannot adjust the LEDs individually.<\/p>\n\n\n\n<p>Addressable LED strip control is very different from analog. I am far from an expert in setting up addressable LED strip controls. However, the basic requirements are as follows:<\/p>\n\n\n\n<ul>\n<li>In order to use digital control, you must first have a digital LED strip. <\/li>\n\n\n\n<li>In addition, you will need a computer (many people use an Arduino or a Raspberry-Pi) to process code and send the signal to the LED microcontrollers mounted on the strip. <\/li>\n\n\n\n<li>Finally, you will also need to supply the computer with a program that tells the microcontrollers how to run the lights. <\/li>\n<\/ul>\n\n\n\n<p>Once you add the ability to be able to control each individual LED independently of others, you can create much more powerful effects. Marlon at hometechhacker.com has <a href=\"https:\/\/hometechhacker.com\/finalizing-my-year-round-leds-and-holiday-lights\/\" target=\"_blank\" rel=\"noreferrer noopener\">this cool page<\/a> showing what is possible with a little tinkering and a super-cool program called WLED. In addition, he has a few other articles that explain in more detail about how to set it up. <\/p>\n\n\n\n<hr class=\"wp-block-separator has-css-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"recommended-products\">Recommended Products<\/h2>\n\n\n\n<p>Do a Google search for LED strips and you will get pages of results with countless vendors selling their strips and accessories.<\/p>\n\n\n\n<p>There&#8217;s so many that I can&#8217;t say which ones are best.
