Product Description  These small flashlights throw out an amazing amount of light. They’re durable, waterproof , use Cree XPC-WC-Q5 emitters and common AA batteries. I’ve carried one everyday for over three years now, have not been nice to it, and haven’t had a bit of trouble with it.     We buy American when we can, but these we order from Hong Kong. It’s the best light for the money in our opinion. If you want to spend more money check out Fenix PD32’s or something similar. If you have to have an American made light of the same quality, expect to pay alot more.
