Checked. He dows say âdepends how hot it gets it will stepdownâ BUT packaging cleay shows 4min on 1500lm then stepdown AFTER 4 min to 500lm for 200min...
I think presenter is not familiar with these words and terms and the mean.
But Martin, again, can confirm this 100%
Damn those runtimes are crazy good for an 18650. One of the most efficient 18650 lights Iâve ever seen. Olight really makes the most efficient drivers in the industry. But unfortunately Olight is too stubborn to provide neutral white and high cri options with âgood tintâ (non green). Iâm probably going to skip this despite the amazing performance and aesthetics.
That info is absent from the manual :zipper_mouth_face: I really have no clue, butâŚmaybe it is an SST-40 after seeing the image after the destruction test:
Minute 7:49
as far as i know and tested all Olights have a timed stepdown, but you can reactivate turbo as long as the cell voltage allows and the over temperature protection does not kick in
the guy in the OP video is not correct with "1500 for 4 minutes and then lower to 500"
i had max 45 °C and 1:40 mins to drop under 1500 (max was 1650)
level @531 reached after 4:30
Martin, thank you so much for the information about this light!
I am still thinking of it due to the dual swiches and UI, as Iâve been looking for a light like this for a while (smaller than the M2R and similar features).
Will you have any deal for it or the current Olight deal is the best one currently?
ZL beat the crap out of Olight in terms of emitter selection but Olight is miles ahead of Zebralight in terms of driver efficiency. The Olight H2R with 4000K XHP50.2 70 CRI has an efficiency of 135lm/w where as the Zebralight H600fc MKIV w/ 4000K XHP50.2 90CRI only makes 89lm/w. The difference in efficiency between the two emitters is 20% max, so Olight is obviously much more efficient. Also the more recent Olight Perun with the XHP50.2 can do â*500 lumens for 4 HOURS!! Olight is king of driver efficiency.
The thing ZL drivers are really good at is the ultra low moonlight modes that can last an eternity, which is great if you ever get trapped in a cave.
Olight does not offer HI CRI emitter options. But the comparison above is to show the difference in electrical efficiency between Zebralight and Olight drivers. Both use 4000K XHP50.2. The Zebralight 90CRI is at max 20% less efficient than the 4000K XHP50.2 in the H2R. So if you do the math to account for the CRI difference, (135lm/w) / (1.20 * 89lm/w) = 26.4% more efficient. But the more recent Olight Perun, which is an upgrade of the H2R can do a whopping 500lumens for 4hrs, which is MUCH more efficient than the H2R and is MUCH MUCH more efficient than Zebralight.
But as I mentioned in multiple posts above, I do not disagree with you Olight sucks when it comes to CCT, CRI, and tint, which is what is preventing me from buying many of their otherwise attractive lights.
No the Olight H2R is 135lm/w / 89lm/w = 51.7% more efficient than the Zebralight. If we assume a 20% difference in efficiency between 90CRI and 70CRI, which is a conservative assumption without knowing the exact flux bin, the Olight H2R is 26.4% more efficient than the Zebralight. However, if we compare the Olight Perun, which is the updated H2R, it is another 20% to 30% more efficient than the H2R, which means Olight drivers are much more efficient than Zebralight drivers, except maybe at really low moonlight levels which Olight doesnât even offer.
Also one thing to note is that my H2R 4000k is much rosier than my Zebralightâs 4000K 90CRI and usually rosy means low flux bin. High flux bins are usually higher DUV (greener tint). In fact the H2R is the only really good rosy NW Olight I own. The rest are all CW or greenish tinted NW.
I donât recall Olight ever claiming high efficiency. Itâs just that we flashlight nerds studying numbers from test results noticed it. What Olight does claim is high reliability.
