A power supply enclosure is usually rated using the IP rating system. 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). A single power supply can exceed the power limit if it splits the power into multiple outputs as long as each output is within the power limits. 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.

PixelStrip is ideal for use with Arduino, Raspberry Pi and Teensy as it's supported by most LED libraries including FastLED and Adafruit NeoPixel. A major advantage of using a 12v strip is its reliability. This voltage option is much more cost-effective, and uses 20% less energy to emit the same light as an incandescent bulb. However, compared to 5v strips, this option requires more careful planning of wiring and transformer sizing during installation. This way is simpler for home automation because only the one controller is added to the smart home network. For long analog strips, you add repeaters to extend the signal. The repeater both injects power and extends the signal. For a diagram of how this works read the section of this article labeled “Power injection for analog LED strips”.

Step 2: Determine the voltage and watts per foot (or meter) for the LED strip. For example, the Waveform FilmGrade LED strip power draw is 5.5 watts per foot. The strip is made of flexible PCB material, and comes with a weatherproof sheathing. You can cut this stuff pretty easily with wire cutters, there are cut-lines every 0.65"/1.7cm (1 LED each). Solder to the 0.1" copper pads and you're good to go. Of course, you can also connect strips together to make them longer, just watch how much current you need! We have a 5V/2A supply that should be able to drive 1 meter (depending on use) and a 5V/10A supply that can drive up to 4 meters (depending on use) You must use a 5V DC power supply to power these strips, do not use higher than 6V or you can destroy the entire strip

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. Battery life is based on current draw of, again it will fluctuate, especially with the digital RGB strips when patterns and colors are dancing along it. Current draw will fluctuate dependent on the color and brightness the LED is outputting. The way to accurately get the current draw is to hook it up to a multimeter and watch the amps change per pattern cycle, take note and do some calculations. These strips require fewer components to get them running, and there is some leeway as to exactly what values of components you can use. The capacitor in this circuit makes sure that the 5v LEDs get a steady power supply. The resistor ensures the data signal received from the Arduino is free from any interference. 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. Higher voltage means longer runs
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. If the strip is waterproof, it will be coated in clear silicon. Before wires can be soldered to the pads, the coating needs to removed. Using a sharp blade carefully cut through the coating, go slowly so the blade does not cut the circuit board. Once it's cut the coating can be peeled off easily. For that reason, it’s good to ask the question, how much light does it put out compared to power used? This ratio is called the luminous efficacy. It’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. Do I need a high CRI light? I haven’t used the mini-repeaters, but the box sized repeaters I’ve used usually can handle 6A per channel. Notice here that the voltage across the LEDs has only dropped to 2.9375V compared to 2.75V with the 12V strip.

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. An LED strip description often includes a 4-digit number such as 5050 or 2835. The number usually describes the size of the chip. They come in 4 meter reels with a 2 or 3-pin JST SM connector on each end and separated power/ground wires. These strips are sold by the meter! If you buy 4 meters at a time, you'll get full reels with two connectors. If you buy less than 4m, you'll get a single strip, but it will be a cut piece from a reel which may or may not have a connector on it.If the piece comes from the end of the reel, the connector may be on the output end of the strip! Hoping for some advice. Had these installed yesterday and hoping to figure out a way to achieve controllable dimming:Tin the pads with some solder and do the same to a stripped piece of wire. Cut a piece a heat shrink tubing and slip it over the strip before attaching the wires. Lay the wire on top of the pad, come in with the soldering iron and heat the wire and pad up until the solder flow joining the two. https://www.aliexpress.com/item/32990957443.html?spm=a2g0o.productlist.0.0.5e04261ap47WFD&algo_pvid=f0d17521-a63e-4426-9351-0afd5199212f&algo_exp_id=f0d17521-a63e-4426-9351-0afd5199212f-1 These three for loops take each color up to its full brightness over a time specified by the fadeSpeed value.

The cut lines are located between the groups. Therefore, the smaller each group of LEDs, the closer together the cut lines can be.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.
