DIY 4000 lm canister dive light

[stevetto]

I have started to make my 2nd canister dive light.

Main features:
- quad XPL-Hi ~4000lm output
- Li-ion battery
- piezo switch
- Goodman handle
- 3 modes 25%, 50%, 100%
- high strength aluminium canister and light head
- PC or multi layer front glass (might be hardened glass)

Looks fabulous.

Nice build.

PS: ratio INPUT (cost) .VS. OUTPUT (value) is very ungrateful......value of self self-confidence - PRICELESS

Satisfying. I enjoy seeing a quality build! Please keep us posted.

What about glass on the outside with PC underneath?

Where did you have the cannister made? I have a diy light build planned but I've not come up with a housing that I like for the light yet.

You will put some aspherics lens in front of these led's ? ( because XPL without dome have tighter output angle and they are much better for sharp focusing ? )

Mandatory hardened glass in front ! PC is heat insulator and stores heat while glass is better heat conductor . PC at time become foggy.

The canister is also DIY. It is quite big compared to the lathe machine size and capabilities so it was a bit tricky to do.

I do not plan to use aspherics, I will use 4 small reflectors.
I use PC with my existing canister lamp and I have no problem with it. Hardened glass of course is more professional but it is more difficult to produce. The future plan is to use multi layered hardened glass.
I have crack tested a multi layer glass (was not hardened) and I was really satisfied with it. Hardened glass has to me much better.
