Brainsick67, thanks for the review. Now I know that two pieces are plastic. Good thing is that it will be lighter.
I personally think Acebeam has given up to compete with Imalent this round. They don’t release any info about their future beast to hold on their potential customers who want to buy big flashlights. Looks like their plan is to watch Imalent release MS18 and see how it goes.
Then it is quite sure they really design active cooling for lumens higher than 10k only. Their thinking might be that DX80 has no fan and it is 30k lumens.
But I think if there is a active cooling feature, why not have it for all modes, let the temperature decide. If user uses Turbo and 25k for let’s say 5 minutes, and then switch to 10k lumens, MS18 should still be very hot.
I have ordered a R90TS,but my order is in the processing status till 24/05, because they try to fix a problem with the plastic case which is in the box.I think they start again shipping at 06/06.
You can’t manually turn on fans at any level. Just when flashlight is off. That is sadly limits the use of the 10K level. It is better to use 22k if you don’t mind the fan sound vecause the light is cooler in that level than 10k. At 22k I measured 50°C at head after 10 minutes.
Just made a test.
10K 15 minute run. It reached 81.8°C which is a lot! No fan kicked in. But it slowly decreased output in 1-2minute steps to about 85% in 15 minutes.
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?
