In such small Lights, W2 is going to run cooler, therefore longer. The SFT40 runs a bit hotter, but in the excellent Convoy M21F there is plenty of cooling fins to help it. The SBT90 is a wonderful emitter, but it is only viable in large lights with mass and heat disapating design. It's ludicrous to put an SBT90 in a pocket light. I have it in a large Noctigon K1 and it will maintain turbo for about 10 minutes.
If we are talking about turbo only then yes it doesn't make sense to have the sbt90.2 into a small host like the Emisar D1. But as an owner of a huge Convoy L8 and the D1 both running the sbt90.2 emitter i love it on the D1 when i am using it daily. Meaning if i have the output at around 40% i still get huge throw while also having great peripheral illumination, it doesn't get warm and the runtimes are excellent! And i still get that huge output of 4500lumens when needed even though it can't sustain those for too long the fact is that i sincerely don't need it to be able to. I use mine D1 as an edc and love it at lower outputs, it is so efficient at those lower levels that i just keep turbo for when i need to illuminate briefly at longer distances and then i just reduce the output and walk towards where i need to. The L8 on the other hand is truly a beast, i have that permanently in my car for search and rescue purposes as it's huge for any other situation eitherway. I know i repeat myself but you should definitely try out the sbt90.2 on a small edcable host at lower outputs and prepare to be blown away by the performance. What i did was that i hit a wall with my sofirn sc31pro on turbo and then i ramped up my D1 sbt90.2 next to it till i matched the luminosity of the hotspots. It turned out that to get those even the sbt90.2 needed only to run at around 25-35% of it's power. And you can keep that performance way longer and with the light not getting warm at all. Something that even the sc31pro cannot sustain cause it will get toasted by heat by then. It was then that i was very very impressed with the performance of the D1 sbt90.2 that i now looking forward to see this emitter even on smaller head diameter hosts than the 35mm of the D1. With just a tad fatter head diameter i can multiply the efficiency of what the sc31pro on turbo gives to me by almost a factor of 8x.
sft40 seems to be the most versatile led
I really need this exact video, thanks

Wind wind and more wind noise. Ugh.
