    Thinking MT-G2 2X15270

    Hey guys Chris and I are thinking about making a mule that is about 2.8 inches long with
    2-15270 IMR batteries driving an MT-G2 LED and an output of about 2,000 lumens, the diameter would be about 0.8 inch.
    It will be a twisty, now the trick if we can find a board small enough to use that will handle the large LED.
    Let me know if there would be any interest in this project.

    Thanks
    Bob

    Why MT-G2 instead of XHP70 ?
    ... is the archimedes peak

    Because the 4 die set in the 70 won't work very well in a mule, it is kinda like
    the old P7 with it's 4 die set. The MT-G2 is much smoother, even if you were going to use an optic. Peak
    still uses the P7 in some of their older units and beam shot isn't very pleasing, even with a diffuser.

    Why not one of those "honeycomb" optics, like Malkoff used for the old M60-MCE ?

    A small optic won't fit that large of an LED, the head would have to be way larger than we want. We want to keep the
    head as it is about .8 of an inch and keep the overall length under 3 inches, no optic will fit that large of an LED
    and even come close to that size, unless you have some answers. It would take about a 12-13 mm optic for our target size and
    they are to small for that LED.

    Sweet! That's going to be one tiny little mule, with ~2000 Lumens!
    Count me in, Bob!

    What's the max. current the best 15270s support these days? Their capacity and max. discharge C rate has always been anemic.
    Looking to buy a LF2XT any age/type/condition. Also very interested in Aleph, Erin, and Tranquility Base stuff, please message me !

    Actually it's better than you think it's a little powerhouse for the size.

    ---------------------------- Continuous Discharge Amps -- Maximum Discharge Amps --- C Rating
    Efest IMR10440 350Mah --------------- 1.4 AMP ---------------- 3.0 AMP -------------------- 8C
    Efest IMR18350 800Mah --------------- 6.4 AMP ---------------- 8.0 AMP -------------------- 8C
    Efest IMR14500 700Mah --------------- 5.6 AMP ---------------- 7.0 AMP -------------------- 8C
    EH IMR15270 400Mah ----------------- 3.2 AMP ----------------- 4.0 AMP -------------------- 8C

    So the 15270IMR has over twice the discharge rate of the 10440IMR, we use the 10440IMR in many of our torches and they work just fine.
    Thanks
    Bob

    Sounds awesome Bob! At 2.8 inches, that is barely longer than the cells..

    Lots of WOW factor, I'd be in for 1 or 2.

    Looks like we can't find a board small enough for the MT-G2, but we did find one that might work with the XHP-50
    I don't know until we fire one up, I really didn't like the 4 die, but that might be the only choice. I hope we can keep
    the size down it's going to need a larger heat sink also. Stay tuned this is a work in progress. We are opened to any ideas
    that might be of benefit with this project. Will let you guys know of how the beamshot looks.
    Thanks

    Working on a new driver should be ready in about 60 days.
    Actually now we are working on the XHP70 as the LED. I'll let you know of anymore
    updates.


    Thanks
