Firstly, make sure that your board can take 5v power in before attaching it to the power source. Almost all development boards run at 5v through the USB port, but the power input pins on some can sometimes skip the voltage regulators and turn them into toast.

We now know that we want to use a a power supply that can provide 1.2 amps and 12 volts. Keep in mind that the current draw per LED is at full brightness. If the strips are dimmed through a PWM pin on the Edison, it will take less current. Going by the max amount is still a good guide to know if you have enough to begin with. If you plan to just plug your LED power into an existing outlet, you don’t need to worry about violating building codes. As long as you’re not tapping into mains voltage or running wires inside walls, you are in the clear. The calculation is fairly simple. All we have to do is divide the amount of voltage across the resistor by the total voltage: Total voltage of stripFurthermore, 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. Efficiency Finally, you will also need to supply the computer with a program that tells the microcontrollers how to run the lights. 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. Sometimes you will see E for 'electromotive force' instead of V for 'voltage'. They're the same thing.) It’s easy to see that higher voltage strips suffer from less wasted energy. LED’s use such a small amount of energy that this doesn’t add up to much for small installations. But, for whole room or commercial installations, the difference in power usage can become significant.

The plastic cover will diffuse the light. This will make the light from the LEDs appear more uniform. 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. An LED light can be built to give off a CCT of 6000K (to match daylight). But if the spectral power distribution doesn’t closely match natural light, objects will always look “off” when viewed under the light. Is 12V or 24V Better? See how we helped Popcorn, a bar & restaurant in central Chester, create a warm and inviting ambience by integrating white-tuneable LED strip lighting to accentuate the venue's timber features and historic character.In most cases, voltage drop will cause problems long before your controller runs out of capacity. Wireless protocols If you’re looking for a waterproof power supply, I recommend making sure you get an IP67 or IP68. These are expected to be fully submersible.

When shopping for LED strips there are a few things to consider. First is functionality. If you are planning to use the strips mostly for ambient lighting, then a simple 12v RGB LED strip ( SMD5050) would be the right choice. LED strips are commonly powered on 5V, 12V and 24V. The number of LEDs per meter (lpm) factors in the power calculation as well. Strips can be 30, 32, 60, 144 or more per meter.

However, the connections made by the clips are not as permanent as solder. They are vulnerable to corrosion and movement. With a single power supply, power can be injected by simply connecting the power supply wires to the V+ and V- wires wherever additional power is needed.
