Welcome to CPF, Magger. If this light performs like the Dorcy Metal Gear and you can get it for $10-$15 and you don't mind the large size or the 3 AAA configuration, then it's probably okay. I've got the Metal Gear is use as a "back door" light and it works fine, but for a bit more there are much better alternatives. If you're looking for options be sure to check out The Led Museum and Flashlightreviews for ideas. Great sites.
