This product doesn't list any estimated battery use time (i.e. 30hrs at full brightness). I really like the specs on this lamp, but that info is pretty vital. BD doesn't have it on their specs either. Any way to determine this?
I did some digging and I found that there isn't an overall estimated battery time due to the dimming function on the Black Diamond Sprinter Headlamp. They do list what the battery life for the maximum and minimum light settings and they are 6 hours and 42 hours respectively.
Awesome! Thanks Wally!
