My only real gripe with my current black diamond headlamp is the power switch. It does not disconnect the batteries from the light. That is, if the batteries are left in then over the course of weeks and months the batteries slowly drain. Sucks. I have been looking at the e+ light and I see the switch is an actual mechanical rotary switch. Can any users comment on the battery life of the unit in the off position? Is the battery still slowly drained like the (still mechanical sort of) more typical push button switch?
thanks, Matt
