I have two left. Had to change out the batteries for newer ones but they still work great. Only light I have ever used that I shined from a campground at Independence, CA lighting up the highest peak in the nearby Sierra Nevada mountain range in November and the only other person up there shined their headlight back. I believe they used a Petzl Myo XP by the limited burn time they had on turbo and the bluish tint. That had to be a good 10 miles away, at least. Don't use in summer. You get all the mosquitoes within miles rushing in on your location. If they had this light with a lithium polymer battery to lower the weigh and increase charge cycles, this light would be more amazing. Best used now for off-roading with church group at Ocotillo Wells. Keeps people out of trouble when they see what is and isn't safe to ride down at night and good for working on damaged vehicles when you have others zooming by.
