Imalent MS18 with 100,000Lumen and R90TS with 36,000Lumen

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.

But just above 10k levels.

I think easier way is to include 10k or all other levels in the active cooling protection.
Manual fan on during light on is nice too.

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?

Now it is charging again to make that one too with full batteries. :wink:

YouTube

something that need to be mentioned…

I must have made you do this?


of course my friend! :D

every reviewer / youtuber can / should help to educate the audience i believe.

the MS18 does not look as impressive in real because the tree is blinding and my eyes adjusted to the light in my garden

That’s crazy output for a tree to blind a flashaholic. :smiley: :sunglasses:

Thought so, most Beam Shots dont look good, FLASHAHOLICS look the best to me, but ill try MANUAL TONIGHT.

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.

It is hard, i made a MS18 vs X70 vid, will upload soon, i ised differnd Exposers in the vid.

MS18 22000 lumen level runtime test with temperature measuring:

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 :wink:
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.

Anyone have the r90tc in hand for review?

let me know if you need something special

Correct. The output has a decreasing slope in output. I also have my review up if interested: https://1lumen.com/21700-reviews/imalent-ms18/

Let me know if you have any questions.

I think I was able to clean up the above post.
