I think you are referring to thermal regulation... Active cooling does not exist in any of lights. From Maiden666's review https://budgetlightforum.com/t/-/47092 you could see X80 is above 50°C @1min which Astrolux MF-01 is not programmed to go beyond this mark. To be honest, 70°C in 2min is pretty insane.
I think comparing this light to an acebeam x80 is ridiculous.You could buy 2 mf01’s, a BLF GT,and aemisar d4 to throw in your pocket for what it costs.
Once again.
Nobody is talking about pid regulation with turbo return after temp goes down.
One guy just supposed that there is no real thermal step down in MF01. I.e. step down time do not increase when heat spreading abilities increased (by any external factor).
I feel the MF01 does a good job protecting its light, it does drop the output depends on temperature. Remember, I was running on high mode for almost 35mins so the light is already hot. I go from high to turbo without cooling it down.
When the light steps down I can choose to turbo it back on. But the light would just step down again to protect it.
The temperature isn’t really that bad to my hand at all to be honest… I can still grab the light by the head on turbo.
And I just tested turbo mode on MF01, it runs about 1 minutes and 37 seconds before I see the step down.
And test my HaikeLite MT03 (over 9000 lumens) runs on turbo over 3 mins and I see no stepping down… the head is no where near the temperature of the MF01 on 1 minutes turbo… I guess Nichia is just a high heat light. Maybe XP-G3 has lower heat?
V1 of the driver didn’t reduce for a few minutes (Nichia version, Samsung 30Q, used outside 8deg C/44F, ~20mph wind, light rain; the head was ~40 C / 104F). I stopped the test after 4 minutes, no brightness reduction.
