So i was hesitant to buy this. It was worth it. Battery seems to last longer than my 1200lumen headlamp. It’s super bright. Easy to work simple on/off button, +/- brightness level, push and hold + for focus brightness, it’s bright! I highly recommend this
This headlamp is plenty bright and has both spot and flood with a ramping mode. Seems durable and well built and should have decent battery for an 18650 lamp.
