Hello!
I ordered a Zebralight H51 which is on its way (it will arrive next week maybe) and meanwhile I have been reading specs of other AA lights. As an example, all this data is from Internet:
Fenix HL20:
* Battery: 1.5V AA
* LED: CREE XP-E R2 (unknown tint)
* 105 lm: 1 hrs 48 mins
* 48 lm: 5 hrs 30 mins
* 4 lm: 56 hrs
* Regulated: yes
Fenix LD10:
* Battery: 1.5V AA
* LED: CREE XP-G R5 (unknown tint)
* 100 lm: 1 hrs 48 mins
* 45 lm: 4 hrs 40 mins
* 13 lm: 11 hrs
* 3 lm: 70 hrs
* Regulated: yes
Fenix LD15:
* Battery: 1.5V AA
* LED: CREE XP-G R4 (unknown tint)
* 117 lm: 1 hrs 30 mins
* 8 lm: 39 hrs
* Regulated: yes
4Sevens Quark AA S2 Edition:
* Battery: 1.5V AA
* LED: XP-G S2 (unknown tint)
* 0.4 lm ANSI: 422 hrs
* 4 lm: 48 hrs
* 19 lm 6 hrs
* 83 lm: 90 mins
* 95 lm ANSI: 57 mins
* Regulated: yes (only non-strobe modes)
4Sevens Quark MiNi AA S2 Edition:
* Battery 1.5V AA
* LED: XP-G S2 (unknown tint)
* 4 lm: 39 hrs
* 21 lm: 6 hrs 12 mins
* 70 lm ANSI: 2 hrs 15 mins
* Regulated: it doesn't say (probably not)
Zebralight H51:
* Battery: 1.2V LSD NiMH AA (Eneloop)
* LED: XP-G R? (cool white)
* 200 lm OTF: 54 mins
* 140 lm OTF: 1 hrs 42 mins
* 100 lm OTF: 2 hrs 24 mins
* 30 lm OTF: 12 hrs
* 8 lm OTF: 39 hrs
* 2.5 lm OTF: 72 hrs
* 0.2 lm OTF: 384 hrs
* Regulated: modes 200, 140, 30, 8 and 2.5 lumens
Quark AA2 S2 Edition:
* Battery: 2 x 1.5V AA
* LED: XP-G S2 (unknown tint)
* 0.6 lm: 1277 hrs
* 4 lm: 120 hrs
* 19 lm: 24 hrs
* 83 lm: 5 hrs
* 180 lm: 42 mins
* Regulated: yes (only non-strobe modes)
I know that Zebralight H51 is measured using Eneloop, but how can it put 200 lumens out the front for 54 mins with an XP-G? It seems to beat all other single AA lights.
Compared to the Quark AA2 S2 Edition, which uses two AA batteries and an S2, H51 still provides more lumens (200 vs 180) and more runtime (54 mins vs 42 mins)! I am not having in mind if they are OTF, ANSI or whatever, but the difference seems too high anyway.
By the way, who knows the bin of H51? Is it R5? Somewhere I have read the new versions are using XP-G R2, is that possible?
In specs you can read some impressive things (are these typos or what?):
* 0.6 lumens for 1277 mins in Quark AA2 S2 Edition: super long low mode! But in high mode (180 lumens for 42 mins), seems worse than H51.
* H51 gives 0.2 OTF lumens for 384 hours but Quark AA S2 gives 0.4 ANSI lumens for 422 hours! Quark doubles lumens, they are ANSI and gives more runtime. Why is H51 better in higher modes but worse in low ones?
* S2 doesn't seem to be that good (for what I have been reading, neither are S3).
What is your opinion about ZL H51? Does it respect what they claim? It seems that beats all other single AA flashlights specs I have read. How can it be possible? Even using Eneloop in others, H51 seems to be much better.
My guess (maybe I am wrong): H51 seems to be optimized for Eneloop, making advantage of it. It also seems to have a very good driver. But if that is the reason, why don't others do the same?
Bonus question: would it be possible to have a 2 x XP-G flashlight powered by 2 x AA giving near 400 OTF lumens for near 1 hour? If so, would it work for 3 x XP-G and so on? I would be glad to see a 6 x XP-G using six AA batteries and putting near 1200 lumens out.
Thank you for reading, sorry about so long text, I hope not to have bored you
I am sorry about my English
