I've got B333 + AVS flood lens. After some experimenting I understood that B343 configuration is more useful for me. Adding to that I use 2x AW RCR123. They drive AVS head at 900 lm (but 4x generic CR123A for backup).

When I compared tint with other lights, Thrunite Archer 1A v3 NW was the closest match.

Few questions,because I recently ordered some 16340 batteries...plz correct me if I'm wrong:

1) The Bravo cannot accommodate 16340 cells; it must be bored to do so.
2) The Alphas will take 16340, though at reduced run times b/c of high output.
3) Will the low output on the Alpha also be higher with a 16340 cell?
Thanks :)

Few questions,because I recently ordered some 16340 batteries...plz correct me if I'm wrong:

1) The Bravo's body happily accommodates 16340 cells as it come from the factory.
2) The Alphas do take 16340, though at reduced run times b/c of high output.
3) The low output on the Alpha is slightly higher with a 16340 cell, but it would likely require a lux meter to detect it.

The above has been corrected.

Your confused a little between 16340 and 18350 cells. 16340's fit fine. Host needs to be bored to fit 18350 cells.
Grizz pretty much covered it.

I see; thanks guys. I just realized that the "16" and "18" references the girth of the cell haha. Why will the output be lower on low on a 16340 cell, but higher on high?

2x16340 cells let you run an AVS head of Bravo as if it had a 3 cell body, but with much shorter run times. But NEVER try to run a Charlie with those cells! You will fry the AVS with over voltage ;)

I see! Can you give me an idea of the run times? I should also be able to run the original M60 head in the Bravo with 16340, right? Will the output be increased because of the voltage or is it regulated? Sorry for being so inquisitive, don't want to blow my module haha

I believe the M60 has an input voltage of 3.4 to 9 volts. When deciding on what batteries you want to use always be conscious of the drop ins input voltage.

You're missing a little detail there. It looks like you've suggested to avoid 2x16340, which would work just fine in a Charlie.

Just to clarify, running 3 x 16340 in a Charlie might not be a good idea. I've never seen the voltage range listed, likely because Elzetta is planning on 3xCR123 only.

The head is labeled as AVS (Automatic Voltage Sensing) so it determines output based on input voltage.

If he had a bored 3 cell Charlie host, 2x18500 cells work well. Not sure if 2x17500 cells would fit.
Don't think there are any 16500 cells made yet for unbored hosts. I personally would not use 3 Li Ion cells in a Charlie host. BOOM!

I have run my other m60 2 cell with 2 x 16340, it runs just about as bright as 2 x cr123a, but at somewhat reduced runtime. If the cutoff of the 16340 circuit is 2.7v, then you have about 1.5 v usable from each cell. The malkoff drops out of regulation at about 3.4v, so it just shuts off after the pcb trips on either or both cells. No gradual decline, no noticeable dimming, etc. Since you get a total of about 3v before full termination, 2 cells in series run a total of 750mAh.

With 2x cr123A, you get 1440mAh @6v down to 3.4v with a decline afterwards, useful voltage is 2.6v. I believe the m60 is run at 700mA, so 2xcr123a *should* give it roughly 1.5-1.8 hours of regulated light, followed by a few hours of declining output below 3.4v. I have run mine dangerously low with 2xcr123a, termination per cell was .9v and 1.1v, about 1 hr 40 min on near max brightness, with about 3 hours on declining output until moonlightish output. With the 16340, i have run them till the circuit trips, 48 minutes on a pair of orbtronic 16340 at near full output until it just cuts off. No dimming, no sag, just off. These drop ins are VERY well regulated. Paired with a beastly bodied elzetta, your setup should last a while.

I believe flashlightguide did some testing in one of his reports. Maybe try there. He does some nice runtime graphs as well. Very nice evaluations.

Im tempted to get an elzetta. But that price is hard to eat.

But it is damn good :) For me it is even more expensive as I live in EU. And I DO have it :) Yes, I do suffer mental disorder -- I am a flashaholic :)

One moment should be mentioned: clear lens may suffer beam artifacts -- it is rather hard to place it perfectly centered. But the flood lens is like honey :) Personally for me it produces much more valuable beam profile.

Immediate update regarding Bravo AVS and 16340 batteries: at 3.514-3.515V both batteries the AVS driver starts to emit vibrating light (kind of strobe) -- an obvious sign to recharge that cannot be missed unless you are totally blind :)
