You have a use case of this light to run it stand alone and want the max output it can give based on temp regulation? I can understand having it on a tripod on a high setting, but I was under the impression Anduril didn't do that well in temp regulating these extremely high power lights - TK said this herself at one time.
Certainly if the light is in your hand, it's easy to crank the output back up.
The Luminus SST70 has a smaller die and the 5050 footprint which is good for throw. The XHP70.2 has the 7070 size and also a bigger die than the SST70. The SST70 emits 4000 lumen from a die that is even slightly smaller than a XHP50.
With four XHP70.2 the Haikelite HT70 would throw maybe 700-800m while the SST70 gets 1500m throw. The XHP70.2 would certainly be brighter and more efficient but it also has a yellow tint shift in the beam.
The SST-70 is way smaller than the 70.2. Here it is in the middle with the 50.2 on the right. You can see it’s also a quad die emitter. Maybe 4 SST-20 dies?

It’s die size looks pretty close to the xhp35-hd, but with way more output.
The SST-70 is phenomenal given the near XHP50.2 output at near XHP35 die size. Just imagine if Manufacturers can shave the domes off them; if used in the R90TS, it can potentially produce like 60k lumens at 1.3MCD.
2 in series, and 4 of those parallel. This determines driver design to power the leds. You can have more throw for less $ than this light, but you’ll most likely have a smaller hotspot, and much less bright spill.
For example a single emitter XHP35 HI light with decent sized reflector like the Atrolux MF02, or the Imalent RT35. Both are in the order of $80 with coupon.
And for an even smaller hotspot with less bright spill there’s the upcoming Noctigon K1 discussed here: Emisar D1sV2 respectively Noctigon K1 - #48 by Hank_Wang
P.S. We don’t know for sure the HT70 actually does 1500m / ~550klux
The ad shows that it uses NarsilM. If accurate, then yes, it functions the same as the FT03. I would want some verification that it uses NarsilM, though. Haikelite have tried to make their own ramping software in the past.
