I recently modded one of these 10 Million Candlepower flashlights from Northerntool with an Automotive 35W HID H4 bulb & ballast. Very bright and at a cost of $150. If you want more info, let me know. Fry's also sells a black version of this called the Humvee but it's about $10 more. I have pics, but I don't have a website to post them.
