Description: Want to make a 12 ft GPS wall clock? This is the perfect item to light it up! Even if that’s not the project you are looking to build, these light bars pack quite a bit of light into three small white LED’s and they are very easy to set up with no soldering required.
The white LED Light Bar is a pre-packaged strip of 3 high-output LEDs powered by 12VDC. Each unit comes with a fully assembled and tested PCB with current limiting resistors, a wall-mount holder and peel-away sticky foam backing, and polarized connection cables. Each LED Light Bar absorbs approximately 55mA @ 12V.

I bought two of these to light our computer keyboard so we could use it when the lights were out. I was going to cut an old USB cable to power these from the computers USB port. Unfortunately the desk was designed in a way that I couldn’t do that. Instead, one of them became a nightlight (and I lost the other). I am using a 6-volt power supply and it is bright enough to light up the room, but not too brightly. Because it has three LEDs on it, everything casts three shadows. I plan on using these to make automatic emergency backup lights in the near future.
