That's... a regular halogen lamp with a 100w bulb, probably a projector bulb, in a flashlight form factor with expensive battery, making it hard to mount, and heavy with a crappy time of 10 minutes at full power! And they want $200 for this albatross? Or $250 with the 20 min battery?

How about 250w for $15, comes with a stand and plugs in to a wall for reasonable run time: http://www.menards.com/main/mobile/outdoor-lights/work-lights/cooper-lighting-7-1-lamp-250w-portable-worklight/p-144934 7-c-7546.htm

It'll catch things on fire at close range too. As will all such reflected/focused incandescents.

Or $80 will get you 120w for 20-30 minutes I battery with http://www.amazon.com/Wagan-EL2741-Brite-Nite-Yellow-Spotlight/dp/B002TW92PG. Handle and a stand too.
