    Driver: hipFlex (TaskLed.com)
    Accum: 4S2P. 8 unprotected 18650 with 2 PCB for 4 serial connection. 14.8 V 5 Ah
    Near 6 hours on max power.
    Weight in air 890 g, in water 360 g. max diam 69 mm. bodies diam 51 mm.

    This is beamshot standart reflector for MCE from dealextreme.


    my auto light (60 W Osram) left vs MaxLight


    And I do addintional reflector with buildin 26mm aspheric lens. With it beam angle 60 deagree:



    Distance 1 m.
    In center: 1380 Lux, 300 mm from center 1200 Lux, 550 mm from center 800 Lux.
    The reflector may be changed for few minutes:






    For additional protection of flashlight I do proterors:





    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

    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.
    Resistance is futile...

    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/st...-datasheet.pdf)
    Lens work in water well.

    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.

    Its simple
    Magnets is mounted inside button. Button have stainless steel spring.

    Reed switch is inside body.

    Then you press button switch income to zone of magnet and it begin to close (on). After release button switch is off.

    Reed switch is as smallest as founded. For MaxFlex and fipFlex (taskled.com) driving current is very small.
    But if current is higher then you must use biger switch.

    Sorry for my English

    Your English is fine, there is no need to apologize. I understand how it works but thank you.

    In the pictures there appears to be a copper cup with a Teflon liner





    Is this a separate piece or part of the light housing?







    Is this the bottom side of the switch with the magnet inserted into the center? Or a cover with the center being a separate piece that slides using thumb and spring pressure?

    Usually, types of powder are named: gloss, smooth, moire, shagreen. Type of powder on MaxLight is moire.

    Sorry Its Literal translation from russian. I'm not shure but may be its "fine textured".

    For example http://168.143.10.6/DUPONTCCDOTNET/d...newdupont.aspx you will select color=black and surface type=fine textured.

    Its separate part of switch. It decide next tasks:
    1. Button is sliding not "metal-metal".
    2. Easy sliding of button.
    3. bottom part of spring not slide out from center.

    This is the bottom side of the button. In center - magnet. May be next picture is mopre understandable:


    The switch of MaxHunter same as well as switch MaxLight.

    Thank you for taking the time to clarify that. I got excited thinking you were producing something I need for a non-light related project.

    You did give me the idea how to solve the problem so a big thanks!

    Excellent job on the light, I am sure it will be a big success.
