Wow it says it can do 1,500m, which means this will throw 2.5 times as far as the MT09R if true, which his quite amazing. Also love the deep fins. Heat shedding will be very good on this light. Also it’s the first time I’ve seen 8x 18650 without needing a carrier
Does anyone know if the “built-in advanced intelligent temperature control settings, can automatically adjust the brightness according to the working state of the flashlight and the outside temperature” means it can also increase output as it cools like Anduril? The thing I didn’t like about the MT03 and MT09R with NarsilM is that it only knows how to regulate output downwards as the light heats but doesn’t know how to regulate upwards as the light cools. After a few minutes on the MT09R and MT03 NarsilM, the light is only a couple hundred lumens and doesn’t climb back up. Not good when used for tailstanding, which is one of my use cases.
It looks like Haikelite just adapted the the MT09R driver and NarsilM to fit this light. So the thermal control only regulates downward.
My suggestion when tail standing is don’t start out at a super high level. Start at a few thousand lumen. Then it doesn’t have to ramp down suddenly and get stuck at a low level.
Depending of what Toykeeper has already made, you should be able to reflash it to Anduril. We would need to verify the driver design first, though. If it’s designed just like the MT09R (twin FET with resistor bank) then the Astrolux MF01S version of Anduril should work.
Possibly, both are 6v, use Atiny85 mcu’s, and use dual FET’s with resistor banks.
There may be variations in the mcu pinout which would require a software modification. I think Lexel made the MF01S resistor bank go to about 500 lumen. That’s pretty low. I’m would imagine TA made the MT09R resistor bank to allow a higher output. So you might have to add/change some resistors on the MT09R driver to give smooth transitions between the channels. So in theory it can be done.
I’m just thinking of this off the top of my head. I don’t know if anyone has actually done it. I just know there are a lot of design similarities in these two drivers.
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.
