First off, I’m sorta new to LED flashlights and emitters, but I’ve been in this community for a long time, I’ve built a few flashlights with the XHP70, CSLNM1.F1 (W1 Green) and the SBT90.2, but I think I just found something on mouser that’s reminiscent of a W1 Green but may have the power to match an SBT90.2 in terms of throw, here it is: The LE CG P2AQ-VRWP-A-0 It has a 3.2 x 2.6 mm² emitting surface, and can apparently spit out anywhere from 8200 to 12100 lumens at 6 Amps (depending on the bin). It’s similar to a XHP70 in terms of how it’s wired. it’s basically 4 LEDs in series and it’s forward voltage is anywhere from 12.8 to 15.2 Volts. It’s fairly pricey at $36 on it’s own MCPCB/Thermal Substrate, but I’m on the verge of buying one and throwing a fun optic on it to make a stupid powerful thrower. Let me know if this is too good to be true because of/or something I missed.
It looks like that MCPCB would be a pain to centre in most lights designed for standard round or star-shaped MCPCBs. However, I like the idea of a Molex connector for quick and easy emitter swaps. 
I might, it’s a green LED, so by design, it’s going to seem absurdly bright 
So yeah, not really a comparison to an SBT90.
