This LED kit contains a 3W LED disc (32mm diameter) and the 5V to 12V USB cable needed to power the 3W LED disc.

These LED discs are the brightest LEDs we've seen and are just fantastic value.

These 3W LED discs need to be powered from the 12V USB cable that is supplied.  A standard 5V USB cable will not work.

They take just minutes to solder and are bright enough to make a usable desk lamp.
