We can now add Kel Tec to the list. Yes, the Kel Tec that makes guns is also making two different types of flashlight. I have yet to get my hands on one, as they have only become available in the last few weeks.
I think MBI (match box instruments) should be added to the list. I have bought 2 of there lights and can't speak highly enough about them (The HF is Probably the best flashlight I've ever bought). Amazing little flashlights and the customers service is second to none.
