Simon, I received your new M3C today the one without a head spring. Spring tension on the 26800 with extension and the 26650 with the body tube only is mild to weak. On moon mode a mild tap will turn it off. Other modes it flickers. My quick fix so far is to remove the retaining ring. Press a P60 outer dropin spring into the hole along with the supplied tail spring. It fits very snug but a longer stronger tail spring is needed.
There is a possibility that this is a temporary solution to the problem. The spring will squeeze again over time and everything will repeat itself. I think need a more powerful spring or a double spring for flashlights with heavy 26650 batteries.

It looks wicked. I hope there’ll be an adapter for a 21700/26650 because I can’t get a 26800 in New Zealand. I can get the light shipped with one, but no spares are possible
Yes, it’s a sample ,but the driver is not good ,
it’s a FET driver, The manufacturer claims that the maximum output can reach 25A, but when I measured it was only 19.2A
spring can soldered on the the 26mm plate, The area used for welding the spring on the driver is too small, and I cannot find a suitable spring that can withstand large currents.
Love the design on the new 26800 light! Finally a proper SBT90.2 mid size thrower with adequate cooling. I’ll sure order one when the driver and spring issue gets sorted out. Just squeeze in a bigger FET and worst case scenario use solid brass +ive contact and 18awg bypassed rear spring.
