Three ultra bright LEDs mounted on a board which can be plugged into a regular USB port to give you lighting.
It's super portable - Carry it in your pocket, put it in your wallet, chuck it in your glove compartment or hang it together with your keys. With USB port available almost everywhere, you won't have a problem to use it.
This stick can also be used without USB port. Just connect power source to the +5V and GND lead on the stick (check USB standard pinout specification) for lighting.
This USB LED stick gives you cool white lighting. Confused between cool white and warm white? Cool white LED is brighter of the two. It appears more bluish. On the other hand, warm white looks closer to yellow, similar to incandescent light.
