Might be a decent buy at only $12. This site claims it has a Q3 bulb and produces 120 lumens. I'm not sure about that battery box at the back of the head though, sounds rather uncomfortable.
its a quality headlamp super reliable had a few years plenty ruff work and still strong , but its hungry on AAA's and it cost me $100 au and that was with $20 discount ,yeah twas worth it forsure .. this looks ok for $12 ..AA's good for casual use I would think
