Thank you 
Well, if this M200 works as the new Skilhunt H04 Headlamp, the turbo is timed and not heat-controled. Narmattaru reviewed that headlamp and showed that after that timed stepdown the turbo could be attained again for the same “cycle”.
He pointed that this could be a disadvantage both for the light (due to accumulated heat) and the battery. Also for that reason, it is better to use a high-drain cell!
Hum, I didn’t unscrew the bezel, but I suspect that this is similar to the M150 and other lights, so the bezel is probably easy to unscrew to access the lens.
But DC-fix can also be applicated without removint the lens, although it is not the best solution, eventually.
Yes, I agree, this is not a light to be held indefinitely on high, so the timed stepdowns are a way to cool it down…despite what I mentioned above about “restarting” the cycle.
About the EDC18, I guess it is a little more larger than this. This light is a good light for backpacking due to its rechargeability capacity, the lightweight and compact form.
Also, it seems to be well regulated for long runtimes on the lower modes. Definitely a light I would take on a trip!
The EDC18…is only missing the shorty tube and the aux leds to be a best seller
