Nice collection. I got a bunch of Olights during their BF sale. I’m surprised you didn’t get the M2R Pro Warrior. That is their most beautiful light to date, especially the camo version. The beam from that optic is one of a kind despite the beam being a bit green.

I think Perun you got there has the best driver efficiency of any headlamp I’ve ever seen. The 500 lumen mode can “sustain” a whopping 4 hours. Even Zebralight’s best xhp50.2 is rated for 579 lumens for 3.1 hours but Zebralights always test much less than their specs and Olight test higher than spec. Though the Perun uses a CW emitter and not HI CRI. I didn’t buy the Perun because I don’t like CW headlamps.
