Guys from Extreme Geek built a very high powered flashlight, that capable of lighting things on fire, roasting marshmallows, or blinding your would-be attacker. The flashlight is actually using an Osram HLX 64623 12V bulb which is being overdriven to 14+V, to about 140 watts, with an estimated light output of about 4000 lumens. Hmm…. I want one for my survival pack! Watch the video to see what its like!
