9V High Brightness LED Clip on Flashlight

I bought a few of these super bright LEDs off Ebay from China. $18 for 30. They are 0.5Watt, 55,000 MCD, 100ma 140 degree viewing angle. 6 of these LEDs are brighter then my 3watt flashlight with the cap off and one can light up a room enough to be a night light..

I would put it in the SANYO Envelope Battery contest but it is not a AA, AAA, C, or D.
