If money is no object, you may want to check out these flashlights: http://www.surefire.com/
Surefire came out with "The Beast" this Spring. It produced ~3,000 lumens of white light, or about 200x that of a 2D cell flashlight, it runs on 20 lithium batteries and weighs in at 3.25lbs: http://www.surefire.com/maxexp/main/co_disp/displ/prrfnbr/24204/sesent/00 I say "was" because Surefire has already withdrawn the light from market. It retailed for $3,000 US dollars. Rumor is that Surefire took the light off the market because they were close to developing a more powerful flashlight and did not want to ramp up production.......
