Nope, it's not a laser. This is a 12v flashlight bulb which has been 'overdriven' to create 4000 lumens of light. That's enough to start things on fire. The project is from Makezine, so maybe you can make your own. Side note: I'm sure this isn't dangerous at all...
Implications - The flashlight seems even more impressive when you consider that a regular 2D MagLight has an output of less than 50 lumens. With 140 watts of power, this is one illuminating device that isn't to be trifled with. You certainly wouldn't want to leave it lying around the house, because a careless user could definitely do a lot of damage if they weren't careful.
