I have a Quark X aa^2. The 280 max lumen XML version.
If I ran a 14500 in the single tube will it be brighter than 2 AA's?

Quark low voltage heads are limited to 700ma of current.. (per their specs). Same brightness.. just an instant cutoff as the cell protection kicks in.

I think it might actually be brighter. IIRC, turbo mode = full capabilities. If the 700ma is max it can handle how much can 2xAA push out? my 14505 is noticeably brighter than 2xlithium AAs when I go between my AA tube and 2AA tube. I think.

I use this exact setup (Quark AA on 14500) as my EDC often. Turbo is significantly brighter! Just runtime tested it with a 2 year old AW 14500 (probably 100 charge cycles) and got 49 minutes on turbo!

Another discussion that includes 4Sevens explanations:
http://www.cpfmarketplace.com/mp/sh...2v-head-minimum-voltage-to-get-170lumen-turbo
(Battery voltage under full load)
-123x2 head requires 3.6v minimum for Turbo Max brightness
-all the rest requires 2.4v minimum for Turbo Max brightness

that's a clear statement with a clear (because of the technical measurement) result.
thanks!
The Quark AA, AA^2 and 123 (but NOT the 123^2) use the same head. If you run any of those on a 14500 you'll get the output of a Quark 123 and the same runtime as a Quark 123 running on an RCR123. They are the same, but output/runtime vary depending on battery.
Actually, in a large majority of cases 14500s will have greater capacity than 16340/RCR123s, due to the greater volume of the AA size. It's seems conventional wisdom, and often tesed here on CPF, that the stated 750mah capacity is reasonable correct for 14500 and a significant overstatement for 16340s.
This will vary from brand to brand, though. I never did side-to-side runtime tests, but the outputs are definitely the same.
Yes, output, driven by voltage will be the same, but runtime, driven by mah capacity will be different.

What was the verdict? Does it have a higher out put or not? I am interested in doing the same thing.
The answer is NO, 1x14500 will have the same output as 2xNiMh (Eneloop). Using a DSLR as an ambient lumen meter, I measure ~320 lumens with either battery config and it steps down to ~250 lumens at ~ 3:15 mins.

I've been a Quark user for quite some time now, I can say that the output is nearly identical or the same on Turbo. If ever there is a difference in the lumens, its probably hardly noticable. I guess because the light is well regulated.
