I did test for pressure in selfmade barocamera and find crashpoint. Crashpoint is 17 atm (170 meter)

Nice work Z-Max! Looks like a robust and relieble light.

What PCB did you use and how did you put the battery pack together? Was it a tight fit?

Yes, and what happend at 170bar :confused:

Lens was crashing at deep 170 meters.
All connections of body are self-tight - the more deeply the more tightly.

If change lens (form flashlightlens.com) on policarbonat 4-8 mm I think crashpoint move over 200 meters.
Now with my lights people are spearfishing and diving 50-60 meters.

With 52 mm aspheric lens (from kaidomain.com) crashpoint is 240 meters.

This is excellent work, and it looks a very good light indeed.

I followed your 1st thread on this too, and I'd like to hear from you how you want to take this project forward.

Presumably you are going to be offering these for sale? Your 1st thread hinted at that. If so, you will need to post a sale thread in Custom & Mod B/S/T when you are ready.

Let me know how you want to proceed, or send me a PM if you need any other advice or have any questions.

Yes, I would like to begin sales but later.
Now I am not ready to enter the international market.
I do it after end of testing.
Testing now proceeds. The group of testers consists of divers and spearfishers.
This toipc only for show my light :)

So what type of lens was used? How thick was it?

Can you explain that last statement? I thought that when using an aspheric lens on a dive light it's couldn't be the lens exposed to the water and had to have a air space on both sides.

Nice light by the way!

Why?
For example - Barbolight U-04 Zoom (http://www.emin-at.com/web/images/stories/U04Zoom/U04Zoom-datasheet.pdf)
Lens work in water well.

New small lens is inside of dry head :)

Adaptor for lens have standart (for 52 mm reflertor) carving 53x1 and standart height - 25 mm for easy change reflector and adaptor.

Thanks. Very nice and very well thought out. Does it work with protected cells as well as unprotected?

I'm pretty sure that when you focus it under water, it will not be focussed out of the water. The mechanism maybe allows to get it in focus for both conditions though.
The reason is that the refractive index of water is different from the refractive index of air, which causes the lens to focus the light differently. If you search my posts, you can find a post where I made a simulation.

Exactly what is the coating you are using on your torches?

Very military looking, I like it and want to use the same finish.
