6v to a 3v led good or bad idea?

Ya that’s what i was thinking, I’m running 6.5amp on the 40, idk if that would pull more on the xpl2 cuz idk which one got the less resistance,

atm the best solution to get 2k lumens is XHP35HD with a boost driver

XPL2 will drop with battery drain level and 2000 Lumens is optimistic for it

and I got one time a light I sold a couple months before with Bistro DD driver, the guy wanted it brighter and put in 2 18350s
blown XPL bond wires, driver not damaged

Cant find a boost driver for 12v
