    How Bright L.E.D. to light a room?

         I want to record video in the darkness, and I don't want any light to be emitted from the LED, so I'm using an Infrared LED. Which power of LED should get, to at least light a small room? I would like to power this with a 9V battery as well. Should I use many of small powere lamps or 1 bright one? Thanks in advance!
