Nice flashlight but i already got 4 fenix headlamps and the CL27 & 28! Honestly, HM65R-DT its your best headlamp, the warm emiter its insanely good for snow and ice. And the HP16R its also very good, accepting the very common AA! Im sorry, id never buy a headlamp with a nonreplaceable battery at a huge price.

The DT was a big step for Fenix on the warm lighting - The HM65R-T V2.0 has taken that a step further with a bigger TIR lens. The HP35R battery is replaceable, but you have to buy the battery pack unlike the HP30R v2.0 battery pack with 2x5000s. (interestingly the HP30R v2.0 battery box works with HP35R)

"Overheat stepdown at 55C" presumably the operating temperature on max 4000lm is greater than 55C, I am guessing closer to 85C. So. What does the max output step down to? In lumens? Is it one step or multiple steps? I am guessing in warm conditions it steps down in single digit minutes, in which case not publishing step down lumens is misleading. I am aware the entire industry mis markets their products so I appreciate the fact you even bothered to mention the step down feature. Looks like a fantastic light. Ok. My bad, you very honestly provide the run time graphs on your website but not on any retail vendor sites. The output drops to 1000lm after about 8 mins at 23C in your lab, so I guess even less in very hot weather and a little more in cold weather.

Thanks for the comment Toby - Yes, thermal regulation is always an issue with lighting and ANSI testing as the regime needs seriously updating in this modern age. As you found, we do put the runtime charts up to try and be a bit more transparent and is also in the user manual. The temperature in testing vs outside as you said does play havoc, for instance in this case with the rear battery box, run times can be affected by cold getting to it. Unibody lights have better results using the LED heat to keep the battery warm to offset the cold, but as you said the step downs happen later due to the unit not heating up as quick. It therefore uses more power running at the higher modes giving shorter run times. Like you said, most retailers won't go into that detail as the average customer buying lights just don't really get it.
