Hi, all
Ive been making small dive lights which can be put in my BC pocket.
This is one of them.

The light is produced by putting a Cree R2 LED pill (Dx: SKU 11836) into a C6 casing (Dx:SKU15969).
its length is about 15cm smaller than MTE P7 light (left).

it is a very bright and tight beam light.

The sealing method is same as previously reported.
it is somewhat difficult to replace the tail cap switch because of its smallness.

This is a key stuff i made: a new toggle switch

run time is about 2h30min.
its cost is 2USD (for a toggle switch 1.5USD, a yellow cap 0.5USD).

i had two dives with this light max 19m & 24m depth and no leak.

it is a nice EDC (every DIVE carry) light.

you can see more pics here (FLICKR).
Thank you.

Nice job! It's kinda crazy that we have to do this just to have a "basic" light for diving. When are the dive companies going to catch up to the rest of the world?

Dennis.
