4500k is about the same as gen 2 👍
Anyone here with the A113 gen.3, with the 800lumens burst? Which RCR are you using?

Do they make a 16340?Why not the Elzetta batteries?
Glad you reminded me. This remains an outstanding 'puzzlement' for me, TBD when I get time. It's already on my to-do list.Why not the Elzetta batteries?

In their Alpha Gen3 description, they use this phrase when describing the maximum specified performance characteristics / behavior of the light:
"When using a high drain IMR RCR123 cell,..."
On that web page that is linked to the 16340 they sell (which I'm sure is a quality one and fine for their G light(?), however I see no indication in the description of that cell that it is in fact a "high drain" &/or "IMR" cell. I may be missing something, but...
There is ambiguity there which needs to be resolved. When I get a spare moment or two, I'll try to grab a current measurement on my light, as I've never seen anyone reference a number for that. That should allow us to better resolve the ambiguity. In my experience, numbers are almost always better than adjectives in electronics
As a result of said ambiguity (solely), I use INR / IMR "high-drain" cells in mine for now. It is something I'm not wild about due to my general /default preference for cells with safety circuits ('protected'), and more significantly the light's (apparent?) lack of a LVW (Low Voltage Warning) feature, which itself remains my sole complaint about design of the Gen3 the light. The positives of the rest of the light have outweighed that single negative for me personally however, and I just live with that and use 'best practices' to avoid over-discharge situations - at least until I resolve this outstanding question.
In sync w/ @thermal guy's response, if I do end up using protected 16340s, given my lengthy personal experience and positive results with them (and most of the lights I routinely use are 1x16340 lights), I'll be using the current Fenix 16340 cells, because they are a proven 'known' to me, and I have some on hand already. I would also have high confidence in the ones Elzetta sells, I only lack the experience with them.
What about 16340 Efest IMR16340 V2 700mAh High Discharge Button Top?
Measuring the current draw of the Alpha Gen3 is a little tedious, due to the fact that things are not static at any point during the measurement period (initial "burst mode" operation), and furthermore 2 variables are in play.
I can't do all that with what's in my kitchen
and yet here you are after all of that in your kitchen... stating that...Regarding the 16340 which Elzetta sells, I'm unable to find any rating for 'max continuous output current) either in Amps, or a 'C'-based rating, so I cannot speak to its appropriateness for use in this version of the Alpha. Based on that lack of information, I would not use them (or recommend their use) in the Alpha Gen3 specifically.
Thanks for the replies. Have four AW 16340 batteries laying around. According this review ( https://lygte-info.dk/review/batteries2012/AW 16340

Well, I'm trying not to 'rush to judgement', but in the absence of proper documentation, I think there might be an issue using that cell w/ Alpha Gen3. I said I 'prefer numbers to adjectives', and although I can sometimes get by with either, I'm not getting either one on that 16340 cell, so that's just not good enough. 'Neither' isn't an acceptable option.and yet here you are after all of that in your kitchen... stating that...
Elzetta doesn't know an acceptable battery for it's own light.
rich, too rich!!!
PCB Protection is at 4.4A according the overview. But the test only did a max discharge of 3A.Perhaps, but not sure. These notations from lygte give me reason to have some reservations about answering 'yes' to that, so I guess I'd have to say I'm uncertain on that one for now. Questionable. I'd prefer to see something that can provide 2.5A during initial max output 'burst' phase, and probably something like 1.5 during much of the rest of the run time, although I didn't test long enough to verify that last number because I was only trying to check the max requirement. The Gen3 light (specifically) might not be too happy with that cell. I'd recommend going with something capable of more output. I'm not seeing that "4A" reference you mentioned at the URL, but maybe I'm missing something.
The cells looks good up to 1A, but they are not that good at higher currents. The capacity is lower than rated!"
- Capacity: 750 mAh
- Nominal voltage: 3.7V
- Maximum current: 1A

Elzetta wrote me; "It can be as much as 2.8 amps for the Alpha. You would need an RCR that is capable of at least 5 amps". But why need a minimal 5A battery if it max pull is 2.8A?
That is a very, very good question, and I do not have a good answer. To up-rate the recommended cell current capability to a number ~200% of the values either I measured or they have stated as the maximum current draw of the light is something I don't know the basis for doing. I'd be very interested in knowing the reason for that recommendation. That would be an extremely conservative and up-rated spec from the nominal values, and I don't know why that would be the case. Perhaps Elzetta knows of a situation / circumstance beyond those in my testing which would justify what is (IMO and based on the facts I'm aware of) that level of overkill. I'm hoping someone can provide an explanation for their doing that. Anyone?But why need a minimal 5A battery if it max pull is 2.8A?
