DRY triple XM-L. It's $84 at SBflashlights after 5% for US customers. For customers outside of continental USA, cnqualitygoods is better. Throw would be about 30k cd so that will definitely be in the ballpark of BC40. Lumens wise it is slightly 3X as much as a BC40, probably some 2800-2900 lumens OTF for your High Ridge MO location (ie on a hill, cold and windy). I see that you are 9 deg C now and probably sub-zero in Dec/Jan.
BTW, the latest 4-mode driver has no SOS/Strobe, for your case it's prob 2800L, 1700L, 900L and 200L out the front (times 1.25 for emitter 3500L, 2100L, 1125L, 250 lumens)
Measured - reflected ceiling bounce TK70 = 450, DRY triple XM-L is 540. TK70 is a 2200 lumens ANSI OTF light. MCPCB -> host is good, LED mount surface to host external surface is good, but host external surface to air for heat dissipation is bad for power of this size (it's a small light). So you need moving cold air for operation past 10 mins. It cannot operate for more than 2 minutes in max mode else you risk damage, but that's at 30 deg C ambient zero windspeed.
