The folks at 4Sevens Company have created an LED monster. I struggle to even call this thing a flashlight. It should be called a light cannon or "the blinder", you get the idea.
Why would you need a 15,000 lumen flashlight? I am not sure but I really want one. The XM18 uses 18 separate LED's that are powered by 32 lithium batteries. They are made to order for about $2,500. Wow. Video after the break.
