Guys, a friend of mine showed me a "Forever Flashlight". It's 600 bucks for the large one and 500 bucks for the smaller one (Lucena City prices).

Found this:

There are China-made alternatives at 150 a piece but I don't think they're the weatherproof kind. And my friend says the switch easily gets misaligned.

Has anyone tried this thing? Never needs batteries daw and the bulb will last practically a lifetime. Hmmm...
