Default Making InfraRed LED USB light, need help

Hello ive just had an idea to make an infrared LED USB light as to light up the room more for my camera. i have never done anything like this before so I need to know about USBs. I need to know how much power a USB can output and what pins do what within the USB cable.

EDIT: unless anyone knows of one that i can buy within the UK

This wikipedia post will tell you basically everything you'd ever want to know about USB:
http://en.wikipedia.org/wiki/Universal_Serial_Bus

The following is from that article:
Pin Function
red 1 VBUS (4.755.25 volts)
white 2 D−
green 3 D+
black 4 GND

Basically you can just cut off all the wires except the red one and somehow attach your LED to the red wire.
