About this deal

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. use the microcontroller to send signals to an external solid state relay, which is a glorified namr for a MOSFET. switch the relay with the controller and switch the current with the relay 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. Power supply voltage must match the LEDs

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. Installing the power supply 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! We will be powering our Arduino board by USB for this project. You could choose to power your board using the VIN pin, but make sure you know the power limitations for your board before doing this. Of course, sometimes you’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’t be enough to avoid the voltage drop. 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.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. Compare that with an RGB+CCT strip. Two different chips are used. One creates colors and one creates whites. They are arranged alternately. But, I’ll admit that I don’t know everything there is to know about LED strips and this guide isn’t perfect. So, if you have any tips or things I missed, please let me know in the comments below and I’ll add it to the guide. LED chips are powered using DC (direct current). Therefore, you can’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. How to Select an LED Power Supply

5 volt 5050 Flexible LED Strip - Small Scale Lights

If I have an LED strip that uses 100W, a power supply with 70% efficiency will draw 100W/0.70 = 143W of electricity. If you have a single color LED strip, you wouldn’t necessarily need a controller. You could just connect it directly to a power supply. 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.


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.

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 Learning to work with LED strips is a good way to get familiar with basic programming on the Arduino, but the best way to learn is by tinkering. Modify the above code and see what you can do! If all of this was a bit too much for you, consider starting with these Arduino projects for beginners.

For analog strips, most people will choose either 12V or 24V. Generally, 12V is perfect for small installations, but for large installations, it may be better to go with 24V. Analog strips don’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 all connections.

Soldering is usually the most reliable method for joining two LED strips. But, it’s also time consuming, requires special equipment, and requires a bit of skill. 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. 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. I am installing 2 24volt 450watt underwater LED lights on my boat. These are high powered so not many people have the correct know-how to figure out how to make this possible. I am plan on installing a 12volt to 24volt amplifier to give me the correct input voltage for the lights. There will be a RGBW installed but I was told I also need a booster to create enough power to operate the 900 total watts. Could you help with any input on this type of LED setup?Any visible light can be broken down into its parts by measuring the power of the waves in a given wavelength range. This is often shown in graph form using a spectral power distribution graph. Below is a spectral power distribution graph of daylight. Source
