I'd like to call your attention to an alternate light source I found online this morning. It's a rechargable, packable source that, when inflated, will float in water. With everything that's going on weatherwise lately, it might be a good thing to have. I also thought it might be a good thing to put in your cave pack in case of emergency.
Apparently it's being used worldwide in emergency situations, e.g., Honduras and Japan. They also have a "buy one, give one" program which, when you buy one for yourself, donates one of the lights to one of their emergency programs. Check this out. They're really inexpensive--less than $20. I think I'm going to buy at least one for myself since I live in earthquake country. http://luminaid.gostorego.com/ PLEASE NOTE: Right now, they've gotten so much publicity that they're sold out, but you can pre-order for shipment in late May to mid June.
