    I think he is just referring to a different light. I'm actually unsure of the relevance of the comment. It does not apply to your case.

    I'm looking into the new E21A LEDs. I haven't tested them yet, but they should work just fine within a reasonable Vf

    The battery length is currently the main issue. These lights are designed for low resistance (non-protected) cells. We're working on making additional tube (or adjustable) tube options.

    Are you saying these AWs are not a good length? They are non-protected, purchased new here on CPF years ago. They are about 5 years old, but only saw a few cycles.

    I have had to reshape the spring, as it was catching on the edge of its hole, preventing max output.

    What 18350 cells do you recommend?

    Measuring with calipers in a second (with pics). The battery tube is designed to keep constant pressure between springs the entire time while allowing for the maximum and minimum battery length of various battery types. But there is such a discrepancy between "18650" batteries they can sometimes exceed the length which causes them to crush between the battery tube and the engine. We've used mainly unprotected cells because they are shorter and the batteries typically perform better in this design (especially with the safer chemistries we have available now). I'll post a pic of the batteries we use shortly.

    Typical length of the batteries used in these lights. Gives constant positive contact pressure for no flickering for loss of contact on impact.

    These two lights are now for sale for first-come-first-serve. One is a 18500 "Blaster" light. A good combo of crazy bright and very carryable (sp?) for it's size. It has a SST40 LED that is very bright for it's size. I know this light is a weird battery size, so the battery comes with it.

    The other is a Tiny Nugget 18350 without any flutes for grip. I just think it looks kinda cool. The 18500 Blaster is $100 and the non-fluted 18350 is $85 (battery included). Granted, the non-fluted 18350 is harder to grip for those that work with oil...



    I have a youtube video downloading now to give an idea of the blaster's brightness for it's size.

    Vid showing the power of the little 18500 SST40 versus my favorite old light (Wolf Eyes 170otf). Not fair, but still gives a good idea of this little light.

    Ill take the Blaster 18500, and could I get a Epoch 18350 while im at it? How about a 21700 big E?18650 /21700 Luminite?

    what lens does these lights use?
    tough?.

    how are wires and solder toughness testing and fixes getting on ?

    is this available in 21700 ?

    are these EDC' able ?

    how would these compare to say the other tough lights such as Malkoff and Elzetta, HDS?.



    thanks.

    thanks.
    The optic is a Carclo 26.5mm tight spot for the Tiny Nugget series. The Lumenite uses a 35mm Gaggione in either throw or flood. Yes, the lenses are very tough.

    The light has no wires and the only solder is on the LED pad and 2 leads. The light really doesn't have any breakable parts (I suspect the battery would be the first thing to fail).
    The internals look like this:


    The engine creates cinch-points to maintain constant pressure over the LED leads rather than wires.

    Here is some torture testing:


    The golf test is particularly brutal imo.

    The Lumenite is available in 21700 but that version is currently out of stock.

    Yes, the Tiny Nugget versions are EDCable. I currently EDC a Tiny Nugget in 18350 or 18500.

    My goal is to make these lights the toughest on the market. No electronics to break.

    Please let me know if you have more questions.

    Thanks,
    -Fraz

    Ya saw that but curious if we can use cells a little longer or shorter. Or is the length critical.

    The 18650s are around 2.56" and the 18350s 1.38". The length is not totally critical but it definitely doesn't need to be much longer than those lengths. Some of the protected cells are probably a bit too long. The tube has double springs (positive and negative end) giving you .3" or so of wiggle room, but getting the battery too long will result in the battery compressing in the tube before the piston compresses. I'm tinkering with some designs that have an adjustment mechanism for the longer batteries but they are still being prototyped. For now generally the unprotected, safe-chemistry, high-discharge battery varieties are what I use.

    is QTC the same as say the HDS Rotary Dial - ?.

    Ill let the experts chime in but basically it functions like peak lights with there QTC. the conductive materials are too far apart to conduct electricity but when pressure is applied, they move closer and electrons can travel through it. Its pretty fail proof and has no moving parts. From what I see its just a pill with this material in it and can be replaced pretty quick. Its a pretty cool design.

    To add- the light functions in a similar fashion- the more you tighten either half, the brighter it gets. When you loosen, it gets dimmer until it goes out. No electronics, just compressing a conductive material. Actual threads in play here rather than just rotation of part of the light, and no elf as Hogo says.

    No expert here but I found this Quantum Tunneling Composite: QTC consists of tiny nickel particles embedded in a rubbery polymer material. When QTC is deformed in some way - by squeezing, stretching or twisting - the nickel particles get closer to each other and the material becomes a conductor. The more it is deformed, the closer the particles get and the better the material is at conducting electricity.
    The HDS Rotary uses a different mechanism. Although it ramps up and down when rotated, it increases/decreases in 24 discreet steps...
    I only fear that if something happens to me, my wife will sell all my stuff for what I told her I paid for it.

    Ya not much to go wrong and if Im thinking right even if the pill breaks or gets lost you could probably put a piece of conductive material in the spot and limp home only get one output but.... Not sure so dont take that to the bank.
