The Astrolux MF01 at $80 is quite impressive. I think the xpg2 version measures 12k to 13k lumen. The best part is if the driver fails, it can be replaced by an aftermarket Texas_Ace fet driver running NarsilM from Lexel which boosts output to about 18k lumen! The Nichia version is a few thousand less lumen on turbo but thats because it’s not as efficient.
The big difference between the MF01 and the DT70 is the beam shape since the MF01 uses tir lenses and has less bright spill lighting.
Haikelite also just had a Group Buy on their new MT09R which is a reflector style light using 3 x 70.2 and a Texas_Ace based driver with ramping. It’s not using NarsilM, but it’s similar. These put out 15k and were costing $125.
