The Official Malkoff Junkie thread - Part 2

2 x CR123As are 6 volts - 3v each in series. So, no. You can use a 16650 cell in that length tube which will give you 3.7 volts.

It came installed on a SF L4 body so that confused me. How is the fit on a 16650 inside a non-bored SF E series body?

 

[Grizzman]

Yep, I accounted for the requested cell count. I think it's under 10 from an 18650, my standard.

Cr123s are the same diameter as 16**0 cells, so shouldn't be a problem if your tube is designed for primaries.

Thank you. So does it ruin the LED if two primaries are used?

Thank you. So does it ruin the LED if two primaries are used?

If the LED and driver are rated to use 6v nominal, then 2 cr123a at 3v nominal EACH would power the light at 6v. Therefore, unless regulated, a single 3.7v 16650 would underdrive the module. Physically, a cr123a cell is hypothetically half a 16650, so 16330. 16 is the diameter, 33 is the length, 0 is cylindrical.

Thank you for the help.

I mean, if the Malkoff bezel is rated for 3.4-5v, what are two primaries at 3v each going to do to the LED?

Did Malkoff ever make any M61LLL that were not special order, not nichia and not Oveready? I have two which are engraved M61LLL and nothing else. I know I never special ordered any and the ones I have from Illumn and Oveready have Nichia or an N respectively engraved.

Yes, he did a few runs with regular XPG led's.

I can't be certain exactly what MDC head you have based on your provided info, but this was posted in the MDC thread back in 2013:

Hey Vox,

Gene sent out an e-mail a few weeks ago announcing the change (quoted below):

"We have just updated the specs on the M361-LMH, M361N-LMH, MDC LMH, and Neutral MDC LMH Heads to include the use of two CR123A primaries. The changes are retroactive"

It is that light. Hopefully that link works.

 

[Grizzman]

If it operates in Low - Medium - High sequence, then it should work with two CR123s.

Thank you. The 5v limit on the side of the bezel just confused me, because I know 2 x CR123A's are 6v total. But apparently the previous owner had been using it with two primaries. I was concerned about the light being overdriven and what that means for me when I get it.

Thank you Chevy.

Went out with my brother tonight to play with our Malkoff lights - we had about 7 different models. My new M61LL really impressed me the most. I got it for my bug out bag hosted in a yellow G2 - a match made in heaven! The output is more than sufficient and the runtime is crazy.

Hopefully my next order will be delivered this week, a M61N for EDC. Cannot wait!

My HD Super is stuck at customs. Hope the post can deliver it Tuesday or Wednesday.
Still don't know if I'll keep it.

Yeah mine was delivered late too. Thanks to Christmas . But you will be impressed by it's throw. I feel like I can call Batman with the beam mines gives out

Yup.

The M61LL runs a long time and for all practical purposes works the same as the M61L in terms of field effectiveness IMHO.

 

[dhunley1]

The M61LL is nice. Not my preferred tint, but the output to runtime ratio is awesome. I have mine in a VME head and will sometimes run it on a 14500 battery and it still gets what I consider good runtimes.
