That thermal video is seriously cool!
I have to get this!
What kind of maximum output do you get with half depleted cells? In the Youtube video, you mention in the comments that you need full cells to get turbo S. Thanks.
That was a message that Olight sent me. I’ll test the output with half depleted batteries tommorow, thanks for the suggestion.
Hi Maukka,
Thanks for the great review.
What’s the length of the provided protected cells? Do you have any protected NCR18650B or GA, such as by keeppower, which you can try for a fit?
The bundled protected 35E batteries are 68.9mm long. Other long ones such as Keeppowers work fine, even my 69.2mm long Keeppower 3500mAhs. Only have one 69.6mm protected 18650B, so couldn’t test those, but I’m pretty sure it’s not a problem.
Thanks Maukka. I ordered a Noctigon meteor, do you think I should be regretting my decision now? :exclamation:
The Meteor is amazing, there’s no reason to regret ordering it.
^ Different beasts. The X7 has more raw power, but the Noctigon is more compact and packs lot more functions.
Here’s runtime on turbo s with ~50% depleted batteries, charged to 3.9V. Total lumen-hours are about half.
So yes, 9000 lumens needs a high battery voltage. This also means that batteries that cannot sustain high voltage under high load, can’t provide the max output, just like Olight said.
Wow,
Thank you very much. This is very useful information to me; pretty turned off by this kind of behaviour from lights… So this means that the 9000 lumens are achieved with fully charged protected Olight 3500 (35E) right? So what will happen if you have fully charged 30Qs; would this result in a higher initial output?
Thanks again for your work!
No difference in output between the 18650s I tested.
From the review:
Thanks for all the testing maukka. If you dont mind, could you do a similar 3.9v test with noctigon? Thats supposed to have a buck boost driver.
Well, it’s just about the first 30 seconds, but indeed output seems pretty much the same. Nevertheless, 4500 lumens for over 45 minutes is very impressive; perhaps more impressive than the couple of minutes of glorious near 9000 lumens…
I tested this with semi depleted cells (not knowing voltage); according to ceiling bounce test, the turbo output was indeed identical 
Edit: isn’t it just a boost driver for the Noctigon, not buck-boost?
Tested the thermal regulation by turning the fan on and off on the highest mode. Fan cooled and fan off runtimes also shown for reference.
The thermal stepdowns happens when the surface is at 54-56°C. The increase in output is not instant if you start cooling the light off after it has already stepped down due to heat.
Only after the light has cooled significantly it starts to ramp back up again. I measured 38°C from the surface 6 minutes after turning the fan on at 10 minutes. This is when the output suddenly jumped up a bit for the first time. The surface temperature rose from 36 to 41 during the next 17 minutes while the fan was on and the light kept getting brighter. It finally (almost) reached the output that was achieved with the test where the fan was on all the time. Turning the light off and on again didn’t restore the original turbo s levels, because the batteries had already depleted a bit. Temperature never rose above 41°C afterwards while the fan was on.
I turned the fan off again at 45 minutes when the temperature and output were stabilized. After this the temperature started climbing again and reached 56°C at 52:40 after which a stepdown naturally happened again. Temp stayed at 53° from there on out.
Finally I turned the fan on at the 1 hour mark. The behaviour was similar as before: output increased when the surface had cooled down to 38°C.
The temperature was 40°C at 1h 25min when the final stepdown happened because of the low battery voltage.
Wow, what a great review of a great Flashlight!!
Thanks for all that stuff maukka!

Thanks for the useful information, maukka.
So, only about 2000 lumens after 3 or 4 minutes. That’s less impressive …
P.S.
You’re mentioned by Going Gear at 18 minutes and 40 seconds. Beware of groupies…
Cheers
Thank you for a wealth of information! Nice work.
