Larson Electronics claims its new EXP-LED-51 rechargeable LED flashlight, wielded by a robot or perhaps an extremely tough fireman, can survive a bona-fide explosion. It's a little morbid, considering the torch could keep on shining even after the lights go out for the guy carrying it.
Rated rated Class 1 Division 1 and Class 2 Division 1, the EXP-LED-51 can't survive being strapped to a stick of dynamite. But explosions caused by gas leaks, and other airborne combustibles, shouldn't be a problem. In addition to being tough as nails, the flashlight also boasts an impressive 50,000 hours of operational life. Battery life is another story. The company doesn't specify how long the $320 torch will run at its full brightness setting of an impressive 130 lumens, but in its 50 lumen mode you can expect it to run for about 12 hours between charges. And at its lowest setting of a paltry 1.3 lumens, you can enjoy a whopping—but dim—480 hours of illumination. [Larson Electronics via Engadget]
Update: As pointed out in the discussions, the term 'explosion-proof' in this instance doesn't actually refer to the flashlight's ability to survive a blast. Instead, it refers to the fact that the flashlight can be safely used in hazardous conditions—such as areas where there's a gas leak—without the risk of its electronics igniting an explosion.
