18650 on a neutral white AA tactical (same head as a 123) set on Max here is the time I recorded. Please note this was recorded and I went by the times on the digital recording.
Initial voltage of the freshly charged 2200 AW was 4.16v
Total runtime was 2hr 4min 06 seconds. voltage 2.80v
one things to note: at 2hr 02 min 45 secs, the light dimmed down to about med level then was out 1 min 21 seconds later. The protection circuit was active on the battery. Once the battery cooled it jumped up to 3.14v
Whilst not a 2600, it should give you a good basis for estimation.
Not a single mention of a 17670
Beautiful! Absolutely beautiful.
That's all it took. Simple. Thank you. And now people won't have to guess anymore. At least for the AW cells. I would probably use the 2600, but even I am satisfied.
I really appreciate it... you are the bomb!

With my QAA-T (on 14500) I can let it run til the protection kicks in on the higher setting, let the cell rebound for a couple seconds and then put it on a lower setting and it'll run for a few minutes due to less voltage sag.

i've made my own runtime test before...
Quark AA R2 Tactical head with 18650...
im using AW 2400mah...
i got 2h 17min before the safety circuit kicks in..
didn't realize any changes in brightness, just an instant shut down on Turbo mode..
room temperature was around 27' Celsius, should be a normal standard temperature in my country...
well just to report my results... sorry no volt meter hehehe..
Owned: Fenix L2d Rebel100, EagleTac P100C2 Q5, Quark AA R2 Tactical, LumaPower Vantage Silver Wam White, Quark MiNi 123 Q3-5A, Quark 18650 body + 3.0~9.0v Regular Q3-5A Head + Tactical Tail Cap
To summarize, although 2xCR123 and 18650 have about the same stored energy, the reason the 123^2 head runs longer on 18650 (and 17670) is because of the way the driver deals with the voltage of the cell(s). Besides the 18650 needing its own additional body tube, the differences between these two energy sources are mostly ergonomic and your preference for either rechargeable or throw-away cells.
In order from lowest stored energy to most, it goes: 2xRCR123, 17670, crappy 18650, 2xCR123, high capacity 18650. This hierarchy may change a little depending on the current draw, temperature, and age of the cells.
Is Quark tailcap universal? Does the tailcap of a Quark 2AA turbo fit the 18650 body? Thanks.
Regular caps fitted fine by the AA^2 tactical did not. I tightened, loosened, tightened, loosened etc till it was all the way down.
Works 100% now. Quarks are not designed with lock out.
The Turbo should be the same.
