No idea, yet. As I said, the output was sagging at 30s point, so full 600lm can't be kept for any longer. This was not thermal sag, but voltage sag of my Eneloop XX 2500mAh.
I'll publish both 26650 and AA runtime graphs in the real review. Please wait patiently. :)
I haven't measured the tailcap current draw with AAs, but calculated runtimes with 26650 are:
1h20min on high, 4h40min on med, 80h on low(over 3 days), 1000h on moon (over 41 days)
Ok 'the', sooo convincing - ordering the 6C1, along with some of Hank's great deals on the XM-L2's on Noctigons, even though I literally have 26 bare Noctigons right now...
Nice!This light is def. living up to the hype.Now I just have to convince myself that I don’t need another light.Really, I don’t.Although I do have two homeless unprotected 26650’s, and I am still upset about my defective SF S2200.Hmmmm….
Nite who sorry? I absolutely cannot wait to get mine now, its on the way, I expect it’ll turn up late next week or early week after, Its getting dark sooner here too, get in!
10 lumen brightness continues over 3h mark, I just aborted the test there.
During the 10 lumen period it's possible to switch back to high with a single half click. High is then on for 2-3s and steps down back to 10lm emergency mode. This can be repeated as long as the batteries last.
That photo is a bit misleading.. The spring mod is only on battery carrier negative spring. Doesn't help 26650 usage. [Frankly, doesn't help lot in AA usage either - rumor says Hank is even going to remove it from further versions]
It should be noted that it really is negative spring. Positive end of the carrier doesn't have a spring, which fools me to try to put the carrier in the wrong way around. Carrier spring towards the tailcap is the rule with this light.
As I mentioned earlier, the lens is very clear. Re-checking it now in a direct sunlight shows signs of some kind of coating.
It's not as purple as I have used to see in AR coated lenses, but it shows fingerprints "better" than uncoated lens.
So I decided to test initial OTF lumens with and without the lens and the results were good: Lens cuts only 1.6% (13lm) and performs like an coated lens should.
I think I need to admit my mistake: The lens has (some kind of) AR coating and it performs well.
