Quick note on runtimes for the little single 18650 battery HO1R headlamp on white beam. Jock (Perazzi) this is for you - and others:
Turbo mode - 1000 lumens = 100 minutes
High mode - 430 lumens = 5 hours
Medium mode - 160 lumens = 13 hours 40 minutes
Low mode - 5 lumens = 73 hours
For normal camp/walking mode you'd be using medium (160Lumens) - so alot of hours on one batt. (Many of the wee headlamps these days like Led Lenser only run to say 220 lumens tops - plenty for camper.)
With this HO1R make sure you screw on end caps firmly for contact. Set to make contact in last bit of twist - which means you can loosen batt cap to stop lights coming on easily when in pack.
And remember when charging with usb plugin, red light means charging, blue means charged. When batt low, the front red lights will start blinking.
