ZL beat the crap out of Olight in terms of emitter selection but Olight is miles ahead of Zebralight in terms of driver efficiency. The Olight H2R with 4000K XHP50.2 70 CRI has an efficiency of 135lm/w where as the Zebralight H600fc MKIV w/ 4000K XHP50.2 90CRI only makes 89lm/w. The difference in efficiency between the two emitters is 20% max, so Olight is obviously much more efficient. Also the more recent Olight Perun with the XHP50.2 can do “*500 lumens for 4 HOURS!! Olight is king of driver efficiency.
The thing ZL drivers are really good at is the ultra low moonlight modes that can last an eternity, which is great if you ever get trapped in a cave.
