How small is this thing? Take your Xtar 2600mAh 18650, it's slightly thinner than that and length is slightly longer.
Hm, the color tint data "R4 4B CW / R2 4C NW" doesn't make sense, is it 2B for cool white and 4C for neutral?
good to see the cool white isn't a blue white, but a very usable 2 tint.
Sunwaymans have notoriously green emitters, and combine that with a true current controlled driver and you have a very nasty tint. A sunwayman on a neutral tint is another story ;)
Great review to help bring these products to our attention!
4C for NW probably looks correct.
For CW, it definitely is not 1 series. It could be 2 series.
nice review, thanks!
Nice pics, much appreciated for the review!
From your rubber ring picture, I must say it is a needed upgrade. Small but necessary.
I have AAA and there is a couple of "chips" missing from one of the circuit boards components. Probably because of battery rattle.
I was hoping maybe a bit lower output on High for the runtimes but I think I an deal with it. 126lm sounds not bad at all.
Do you think that i should do a drop torture test for the AA version? Seems like it would survive due to TIR, solid pill inside.
I am thinking of doing a 2-3m drop test. How many times should i drop?
i like your seeking attitude. Looking forward..
Thanks for sharing your thoughts with us 2100. How's the beam like compared to a reflector equipped XP-G R4?
It'd be somewhat better. Something like a very very nice OP. I only have 2 OP XP-Gs, namely the Romisen RC-R2 (something like that) which is a P60 sized light and also the Sunwayman V10A which i guess is the closest for comparison. The DQG has a better beam than the Sunwayman V10A. I guess for such a mini EDC, flood qualities is more important and useful than throw.
I have already posted a photo of the V10A vs the DQG above.
What you can clearly see is that there is spill, and then smooth hotspot. For most lights incld OP reflectors, you get spill, corona, hotspot. It is usually not an issue for semi-throwers or bigger lights because they would be used for > 5m anyway so the corona usually won't show up, but for EDCs this is impt. This is why a TIR lens work.
Cheers 2100, from what I see from your beam shots, it seemed the DQG has more spill. Since the DQG uses a TIR coupled with a XP-E, I would have thought that the spot would be a lil tighter & narrower, hence my curiosity.
The beam is indeed beautiful 
I see that you have just added more clarifications, thanks a bunch.
Ooh, that sounds like a very nice runtime on low. Very interesting.
Thanks for the nice review! Frontpage'd and Sticky'd.
not stick it in 1x AA forum section? 
anyway. good it's stickied. i had trouble finding it.
Oops, thanks for the heads up. It's moved to AA now.
Until it dies, Mr. Bond!
:bigsmile:
Any chance we could get a side-by-side comparison shot of the two tints on high? I'm partial to NW tints but if this CW tint is pure white similar to the EZ AA R2 tint I think I could go for that as well.
Thanks for the excellent review!
Love that smooth beam .
Runtime on Hi with eneloop AA? Please (I ordered one and want to know). Do You measure it?
Hi!
Thank you for your detailed review.
I'd want to know if there's a low voltage cutoff built into the driver (for 14500).
Is the driver a buck-boost, right? I hope it's not a cheap boost driver that direct-drives the led when Vin > Vf.
Is it able to squeeze every mah out of a 14500 without lumens drop, triggering the LVC inside the (protected) cell? Or it goes in a sort of "low battery moon mode" at around 3V?
Thank you very much.
EDIT: see my review in the following post.
