For people curious about active cooled lights, I’ll share some examples built by manufacturers. (from my secret stash, lol) No one off or home built lights.
It is said to do 1.7 hours at 10k lumen using 6 xml2 and one xhp70. As the light gets hot, the fan will cycle on and off to cool it. You can hear the fan cycle at 18:10 of this video. https://youtu.be/wsQwQzVxhy0
The Acebeam X70$750 $629. 40,000 60,000 lumen! 12 x xhp70.2 plus 1 xhp35-HI. 1000m throw. Uses 8 x 18650 battery pack with built in recharging. Video.
UPDATE: The new version has lost the internal fans and now has a fan built into an add-on handle which seems to have a single 18650 in it. Price was lowered and output increased to 60,000 lumen.

The Astrolux MF-05. It’s still very early in its development so there are no pictures, yet.
Nice thread. Specs on the X9 say 25000 lumens @ 5 min then steps down to 6000 lumens @ 80 minutes. I guess the fan does not do that much or am I reading the specs wrong?
The Emalent DX80 does 32000 lumen for 3 minutes without a fan (according to its specs), but I think they built that with a massive amount of aluminum in the head to soak up the heat (plus the finned heatsink bolted on).
With the fan turned off, the X9 might last 60 to 90 seconds at least. That would be my estimation based on its lighter weight. Then with the fan running, it could be extended to the rated 5 minutes.
I think the X9 would be around 350 watts, btw. You would need a good heatsink and a powerful fan to sustain 25k lumen. I think the X9 was lacking a bit in both departments. It had a compact heatsink and a compact fan to keep the overall size of the light small. It’s all about compromises.
Olight charges a lot. Their X7R 12,000 lumen light has a list price of $279 compared to Astrolux’s MF-01 12,000 lumen light that has a $110 list price.
They claim to be a higher end brand. Same for Acebeam, Nitecore, Fenix and others.
Acebeams big 12,000 lumen searchlight, the X65, is listed at $574.
I think the early Olight X9 was going to be about $600 to $700 back when it was first introduced.
I don’t think Astrolux is targeting Olight’s X9. They can easily beat their higher prices.
The MF03 is probably targeting the Imalent DX80 since both are not fan cooled.
Then their MF05 can compete against the Acebeam X70. I’m sure they can beat it’s price, but the X70 might release soon, so they are a ways behind. This might be why they released info on it way before they have any real designs.
