So Brinyte you say? You swill step into 330+ kcd field with that light. But it is not my favorite…
I am settled with 1503UF’s with hand selected lenses(each lenses are superb) that gives “only” about 250 kcd of performance(some best of them of them are very close to 280) but with much nicer tint and wider beam than in B158.
Setup is same for each light I mod(no matter reflector or aspheric). I mod single 18650 lights. Fet driver+dedomed XP-G2 S4 2B with addition of precoolimator lenses on my aspheric builds.
C8 with mine combo would give only around 200 kcd 
And if you guys really want reflector super light, portable and true super thrower for cheap $ nothing beats (literary nothing in that reflector size) Mitko’s Super thrower light aka Supwildfire each of them modded will go over 320 kcd with my mentioned setup but I still prefer aspheric type of beam for hunting and if you’ll hunt with IR led lights and night vision equipment you’ll also see that 90% of led IR lights on market use all kinds of aspheric lights as a host. With good reason…
Mitko’s find here: BLF style 18650 1s thrower( poor mans Olight M2X)
