Black Diamond Iota Lightweight Backpacking Headlamp Review 150 Lumen

I have been using this headlamp for a couple months at home every night walking the dog and finally got it out on a backpacking trip.  First off, it is the lightest rechargeable at 1.9oz/56g.  That is the big selling point.  Easy one button use is awesome, with touch dim is the second biggest feature.  It doesn''t have a red light, but that isn't a deal breaker for me.  I found it useful for around camp, and plenty of light for night hiking.  Very comfortable, and fulfilled the headlamp job very well.  Wish you could replace the battery, but looking at all my lamps and cost, taking into the life of a rechargeble battery, in the end it is a good deal.
