Started with full battery and the start temp was 21°C
And in the glass lens center I saw some condensation after test which disappeared after cooldown. You can imagine if the head outside was more than 80°C the leds could be easily above 100°C:
That’s really nice tracking graph. It tells us how the output behave.
But I find it strange the output drop in steps, not smoothly declining. Is it due to light meter resolution?
Did the 22k lumens output level drop like that too?
The hardest thing to set up exposure same as real life. Because your eye pretty much works as between locked and automatic setting. So if you lock exposure at a low level (like 100 lumens) the levels like 5000 and above will be burned. If you set 10000 then 1000 lumens will be lower than real life. So that is why you need to compare apples to apples like I tried the MS18 with my second powerful light the MT03 TA.
The manual says 22,000 lumens for 67 minutes. It looks like it doesn’t really hold 22,000 lumens at all and drops to ~10,000 lumens at 30 minutes? Also, did it turn off at ~45 minutes? A little disappointing if so. Would you be able to test their claim of 10,000 lumens for 3hr 40min with a similar graph?
It blinked the empty battery signal. Showed 11,73V so I turned it off but I think it was about to heppen any time. Disappointing it not meet the specs but show me another flashlight that can hold output over 10000 lumens more than 30 minutes
For 10K just roll up to post #402
It reached 82°C after 15 minutes in 10K because no fan activation in that level. Impossibble to hold in hand and I think it is not healthy for the flashlight to run more than that in that level. So impossibble to run it for 3 hours 40 mins in 10K If you make 10 minute runs and let it cool down maybe you can reach more than 3 hours if you add the runs up but not in continuous run.
