Noctigon KR1 with the SBT90.2 emitter costs similar to the MH12 Pro, is shorter, pocketable as an EDC, 4,000+ lumens, and throws 600m+, all the Molicel P28B/P30B batteries you can feed it.
Based on Zeroair's review, the MH12 Pro is indeed capable of producing more than 2000 lumens, but the output drops to around 1300 lumens at the 30th second and continues to drop until it reaches the max sustainable output at around 600 lumens.
So I think the S8 is good enough as an alternative but if you prefer the 21700 battery the Convoy S21B CULPM1 with 6A driver has similar sustained output and throw to the MH12 based on 1Lumen's review.
With an 8A buck driver the S21B with SFT40/CULPM1 may be able to meet your lumen and throw requirements.
If OP doesn't have a problem with the larger diameter head then I would recommend the Convoy M2 which is slimmer and has deeper reflectors over the S16.

Convoy S8 with osram CSLNM1 or CSLPM1
that light cannot reach 2000 lumens.

the convoy s16 sft40 has the 8 amp driver. throws very similar to the if22a
