    most definitely. I swapped my 4K for my 5k today and really loving it pure white aspect and flawless beam. Running it with a pair of 18500 cells in a md2 body , extender and high / low ring. It reminds me of my xml nuetral version I got not too long ago, but that was I believe is less powerful.

    That sounds like a good combination. Lately I have been thinking I need to up my game with my EDC. Especially now that itís getting dark a lot earlier. Put a crenellated bezel on it I might be there. 🤔

    So if Iím getting this right. The reason they are still good is because the 91ís driver stops working at 3 volts? This thing ran for like 8 hours at 15-20 lumens and used practically no juice?

    Ok just checked draw. 26 MA with 2AAís. Wow


    WHAT

    You could use the M91B in a G3 with AA cells..... What kind of madness is this? I am trying this when I get home!

    Did this just become the most versatile dropin for real?

    I'm going to try this in my Z3.

    Got way over 6 hours with mine off 2 Duracellís. 10-15 lumens or so. 😁 and when it does shut off you can pop them AA in another light and go for it. Itís the M60LL days all over again

    Lol, just wake up? The last 30+ posts or so.

    Only 2xAA alkalines or Lithium primaries however; NiMH just doesn't have the voltage to fire it up. But like TG is saying, the cells should still be very fresh (~90%) for other uses after they go below the Vmin of the M91B driver.

    I am very curious how long this module might run on a single CR123 however - the voltage of that chemistry is def. more resilient than 2xAA alkaline. Temped to try myself, but at the same tine I'm also interested in seeing the resulting output curve.

    Not quite the champion 60+ hour 2xAA omnivore of the M60LL - but then the M60LL never did 1200+ lumens, lol; Definitely the most interesting Malkoff dropin ever.

    For a single-mode dropin, this is one for the books;
    • 1200+ lumens of flat regulation from 2x18650
    • 4xCR123 compatibility (less so for 3xCR123, but still possible)
    • ~500-600 lumens of direct-drive from 1x18650 (so maybe longer runtimes w/ the declining output ??)
    • ~20 lumens (+/-) for useful time periods from 1xCR123 or 2xAA primaries

    Edit: just don't run 2xCR123 however; I have a feeling that it will attempt ~800+ lumens - until the cells go
