Regarding the programmability of using dual flood and a spot ZL headlamps:
H600mkii on 3.5-11 lumens/1-2 week duration with H602 on 65 lumens/30 hour works really well for me within 20-30 feet, very comfortable working, seeing tools and moving around, while still not too bright for arms length.
Likewise H600mkii on 65 lumens/30 hours with H602 on 330 lumens/4 hours duration looks really balanced to my eye for longer range.
So there's still a little more flood power available and a whole lot more wide spot power on tap.
