your LED is typically gonna take 0.7A to 1A. a 9V battery will last about 10-20 mins at that rate. that makes for a very expensive lighting solution. it would make much more sense to use 2 rechargeable Nicad or NiMh packs (keep one in reserve). better yet, punch a tiny hole in the wall to run some low voltage DC from a wall wart.
