Convoy 3x21D SBT90.2 with the buck driver now available. Has anyone tested runtime and turbo stepdown? (The FET version could only sustain 600 lumens).

   I ran a ceilingbounce test on it. It held turbo for 4 mins straight when I turned it off as it got extremely hot. No thermal regulation is evident. Not sure if this is good or bad because turbo still seems unregulated so better and more methodical testing is needed to figure out just how better the new driver is compared to the older one. Longer turbo times may just be the result of non existent temperature regulation.
   All speculation but maybe the firmware in the driver was changed. Still an incredible light for the money!
