    Walter,


    GREAT NEWS !!!






    Outstanding work , with your last post you make my day !

    I feel a little bad because i think that the price of the V2 is under his value so i'll paypal another 5$ ASAP ( a drop in the sea, i know ) and you can leave out the RC123 of my package, now that the problem is resolved i don't think i need a rechargeable !

    Thanks.

    Data:
    No you do not need a bottoming tap. You only need to clear the first few threads to get a good electrical contact. And yes you can clean the screws with a wire brush. You will need a 2-56 UNC-2B tap and some conductive epoxy. You only need the epoxy to keep the screws in place. The light will work fine without the epoxy but the screws may not stay in place and will require subsequent adjustment. The epoxy we use is Emerson & Cumming Eccobond 56C. This is an aerospace grade solder replacement epoxy that has vary good electrical and structural properties. However this epoxy is vary expensive, a more economical alternative is MG Chemicals 8331. Of course we can not warrantee any work that is performed outside of our control. Using a thread tap on these bars can be risky if you are not used to this size screw. If a thread is damaged than the only way to replace the bar that is damaged is to replace the entire center housing assembly.



    Regards,

    Kyle

    In regards to the batteries....
    Although the recent discovery about the conduction through the screw threads improves the performance of the light greatly, we still highly recommend the use of rechargeable batteries in this light. The circuitry is still optimized for higher voltage batteries and you can expect an increase in efficiency and power output when using these. We are looking in to the possibility of creating a 3.0V optimized driver for this light and if this becomes available in the future we will be sure to notify everyone of this.



    Regards,

    Kyle

    Hey Walter.

    I purchased a V2 Gatlight froma member on CPF, I will be shipping mine to you with my name and address in the box if it is OK with you.

    Thanks!

    Of course, no problem, just send it back, as long as you include your address in the package.

    Sorry about the delays. We haven't had much UPS-Karma lately. The adjustment tools were delivered to another address (UPS of course had no clue, they didn't even know anything was wrong). When Kyle found out the address he drove down there, and found the package sitting on the door steps of an abandoned house!!!! go figure. Then UPS lost another package, and is currently in the process of finding it. Fortunately the batteries got in yesterday. Despite all this, we are able to ship a number of lights tomorrow and a larger number Monday. Which lights these are will be posted on the website beginning of this coming week.


    We are glad that we found the cause of these issues. The lights that ship next work great, and are no comparison to the first batch. Also I am sure the first-batch GatLight owners don't mind a little brightness tune up .
    Hope that includes Singapore!

    NOW WITH UNLIMITED BRIGHTNESS LEVELS - see video

    .......

    Here are the specs:

    -Lux III 50mA to 1000mA (adjustable by using a small screwdriver)
    -Upgradeable to a Luxeon K2 once it becomes available
    -fully waterproof

    The housing design:
    1. Unlimited Brightness Levels (for details see video)
    2. Designed to maximize thermal efficiency by maximizing exposed surface area.

    3. Mechanical housing assembly analyzed using finite element analysis (FEA) in order to insure structural integrity under stress

    4. Materials: 316 Stainless steel or Titanium (both with hand polished finish)

    5. Water sealing designed to withstand depths greater than 1 meter

    6. Aerospace grade 82 deg. flat head screws per military specification NAS662

    7. Housing screws thread staked for added durability.

    8. Assembly performed in accordance with qualified spaceflight hardware procedures and requirements, in order to maximize reliability and quality.

    9. Silicone environmental seals fabricated with the use of high vacuum degas process.

    10. High precission components: <0.0005" tolerance

    11. Heatsink bars pressed into main body under >500lbs axial force in order to maximize thermal efficiency.
    Circuit design:
    1. Circuit board designed to meet the requirements of IPC-A-610, Class 3 (High reliability) And NASA-STD-8739.3 (The same requirements applied to spaceflight circuit boards)

    2. Aluminum core circuit boards to provide maximum thermal dissipation.

    3. Circuit designed to handle up to 2000mA of current for short durations.

    4. Temperature sensor automatically turns off LED at unsave temperature and restores brightness once a save temperature is achieved again.

    5. Future versions up to 1500mA (K2)

    6. Circuit board assembly performed by NASA qualified technician per NASA-STD-8739.3

    7. LED mounted to circuit board using high performance thermal dissipation pad commonly used in spaceflight applications.

    8. Circuit board epoxy potted using aerospace grade thermally conductive epoxy to maximize thermal mass and conduction surface area

    9. Preliminary circuit design rated to 85 deg. C
    Assembly testing:
    1. Assembly tested using laboratory grade test equipment and processes.
    Then we offer in this run only an Aluminum version (tests pending / anodize is still to be determined - whatever we decide in this thread), also we now offer a Titanium PILA version. Then you got to choose different screws to alter the look of your light.

    As you might now Jon S. Burlys will do the distribution of the GatLight outside of CPF - we would like to use cpf to introduce changes and new versions and get feedback we then introduce into units sold outside of cpf. Even though these cpf versions will be a bit more expensive, in return you get hand assembly, adjustable pot (to adjust for brightness and runtime) and the stainless versions will have more of a silver appearance.

    We tried to keep the prices the same as in the first run (the increase comes from including the shipping costs/paypal in the price). The Titanium versions went up in price because our old machine ship refused to do anymore Titaniums at that price we got the last time. Also costs for Titanium went through the roof. That's just the way it is and we can't change it. If you like light weight, we think with the Aluminum version we have a more affordable alternative available (tests pending).

    Also we might add more features in the next couple of weeks...

    Waterproof? Is the battery compartment covered with some tranparent material or what? Seems to me that the batt can get wet...

    The battery compartment itself is not sealed by anything other than the metal rods but the positive & negative ends of the battery contacts are encased in silicone seals.

    WATER
    There is nothing wrong with a shrinkwrapped battery getting wet as long as the poles are sealed. However regarding waterproof we would like to make the following comment.

    • SEALS: This design is vary sensitive to the size and proper installation of the battery. If the right size battery is installed properly we have a vary high level of confidence that this light will remain water tight to 1m - maybe more. However because of this sensitivity we cannot at this time guarantee this performance until we have performed the proper testing.
    • CORROSION: This light has stainless steel components that are exposed to the exterior. Although we have made every effort to make this light corrosion proof (f.e. electropolishing), even stainless steel may rust under prolonged exposure in the right conditions. In order to test corrosion we boiled the housing section of a light in salt water for 10 minutes (10 minutes in this environment is probably much worse than 2 weeks in room temperature water). As a result of this test, we found small patched of yellowish tint on some surfaces. This vary slight corrosion was easy to polish off with a light abrasive, bringing the light back to its original condition. The Aluminum and Titanium units obviously will have different characteristics in regards to corrosion.

    Until we have the time to perform the proper testing to verify the performance of this light at a depth we will be revising the specification to “water resistant” rather than “waterproof”.


    SHIPPING
    Because we are applying the "replacing locktight with conductive epoxy fix "(as previously posted) things take a little bit longer (we've had all lights already screwed together)
    However we are working hard on getting lights out. Yesterday several GatLights (mostly to international locations) were shipped. Those went to the following people: 1st letter of firstname + 4 letters of last name plus country)

    YKuro-Japan
    HTera-Japan
    KSuzu-Japan
    TTeji-Japan
    TTash-Japan
    MKame-Japan
    RKato-Japan
    TGlud-Denmark
    LVasa-Australia
    GHeng-Sweden
    TNato-Japan
    JMill-USA
    MMall-USA
    RSnyd-USA
    RYevi-USA

    The next couple of days we will start working on Aluminum and Titanium versions so we can start shipping those to people who went with non steel versions (while continuing building steel versions).

    The mailman was good to me today, Gatlight SS recieved!!! This light is beautiful! The SS is heavy but solid, reminds me of a line in the movie 'Snatch', "if it doesn't work, you could always hit him with it."(Boris)
    Awesome craftsmanship and nice white tint. Only gripe so far is that it seems to flicker at the lower setings, but at the higher settings it is fine, and bright, waiting for the sun to set tonight to have some fun. Great job guys, this was well worth the wait!!!
    What are you people......on DOPE!?!

    Hello Walter

    Could you please give us a hint on the next Project ?
    I know I heard something about V3 but that's not what
    Im talking about. Any other type of light design ?
    Just give us the Idea....I know we can wait....

    Talking Re: GatLight V2 - now with unlimited brightness levels

    Went to the post office this evening and I'm now feel all sorts of Gat'riffic!

    I need to aquire the proper backdrop and props for some worthy photos, but I figured I would just post up some comparative analysis. I used my lightbox to test a few of my single cell 123 lights with both primary CR123A and the provided Powerizer Li-Ion R123. The primary was a brand new Surefire and the Powerizer was freshly charged. (I was surprised that Tom's results were so favorable for these cells in particular. Very nice.) This wasn't meant to be super scientific, but the box has been proven quite repeatable and is very nice for comparison purposes.

    The contenders:


    (Don't mind the picture. The color and lighting are all off, but I just wanted to throw some sort of visual in.)


    ...and the results.




    It should be noted that I provided the fine makers of my Aluminum Gatlight with my own LED. It has been brought to my attention that this LED may be what you could call an overachiever. Soooo, YMMV. That being said, I'm super-pleased with the amount of light output especially given that it's going through an optic and not a more efficient reflector.

    Walter, Kyle and everyone who has had a helping hand...AMAZING work of art and technology!

    I definitely need to take some nicer photos to do this light justice.

    Thumbs up Re: GatLight V2 - now with unlimited brightness levels

    V2 arrived a few days ago, safe and sound. Simply outstanding !!

    One question; I do have significant flickering at low levels, and much diminished brightness with a primary cell. Was my V2 part of the first batch with the Loctite on the battery compartment screws instead of the conductive epoxy ? (I didn't receive an e-mail regarding this)

    Many thanks Walter, Kyle and everybody who contributed to this stunnning acheivement in design and function.
