I have one with a crank handle that has 3 halogen bulbs that give off a very bright light. crank it for 1 minute and it stays charged for an hour of continuos burning and it has a push button on/off switch. The drawbacks are that it is 5 1/2 inches long X 2 1/2 inches wide X 2 inches deep and it weighs 7 ounces. I have gone through several head lamps that have all quit working...thus no light regardless of the batteries ....and to preserve the batteries I have carried votive candles....so anything that does not require batteries is well worth it to me since I read a lot at night when I hike. So by the time you add up the wt. of the headlamp and band and the weight of extra batteries plus the weight of the candles....it is just about awash with this light. It is called the "Illuminator" but I don't have the name of the company or a website. My wife who is a teacher bought it from a bookseller and paid $10.00 for it. If I find out more info about it, I'll post it on this thread.
