After over a year and several versions I have come up with design that allows me to build and sell a quality canister dive light at a very low price compared to the others on the market. I have sold several to cave divers and tech divers and have nothing but rave reviews

It uses 5 cree leds for 1200 lumens output and a very tight focus. Is small and light but very robust.
Each one is tested to 300 ' before shipping.
