Pretty amazing specs on this guy: 50 lumens (Luxeon I emitter used) not reguated (they brag about how thier discharge curve is flatter than non-regulated alkalines). About the size of a small 2C flashlight.
What would you say if I told you I could build a light of the same size, that would produce twice a much light as this with the same 24 hour, and an even more convenient method of refueling -- instead of refilling it with compressed hydrogen, there are actually two batteries inside that get recharged from electricity right out of your outlet at home via a charging jack on the side of the ligt. It's so convenient, I don't understand why nobody thought of it before
