BD's smallest.

Having a light as tiny as Black Diamond's Iota Headlamp can come in handy on any outdoor adventure. It's clearly an essential for hiking, backpacking, and camping—especially when you have to leave the tent in the middle of the night for an impromptu bathroom break—but it's also small enough to fit in the fullest backpacks for climbing, skiing, and mountaineering. You might not be planning to play past daylight, but mistakes happen and sometimes you reach the car in total darkness wondering what happened. At the very least, the Iota makes an excellent spare or backup; at the very most, the Iota can brighten the way on most adventures that extend past daytime.

Love Rechargeable Tech

  • Familiarity: I've used it several times

Running, walking my dog in the morning, sitting around camp - this headlamp is good for most average conditions you can out it through, and much like the rest of the reviewers, I'm a HUGE fan of the fact I can simply recharge the battery when it dies. Simple, smart and does the trick!

Re-chargeable Brightness

  • Familiarity: I've used it several times

This is a great little headlamp that packs alot of light. Than you are able to even adjust the amount of light which is awesome. It is also rechargeable, so no need to worry about batteries. (It is mico-usb, cable included) The strap is secure and snug, without being uncomfortably tight, and is easy to adjust. I would easily recommend this to anyone looking for a reliable and versatile headlamp.

Light weight and rechargeable

  • Familiarity: I've put it through the wringer

This may be one of the best lights to use while running! Its lightweight and bright enough to light the road and it's rechargeable so you won't have to keep replacing batteries.

"it works"

  • Familiarity: I've used it several times

I bought my husband a second head lamp because he's always stealing mine. I asked him what he thought, he said "it works." It doesn't have the red light that I require (as a photographer) but it does have different brightness levels. What I really liked about it is that it's bright and very little and compact. Considering that he uses his mostly at work I think it's great.

No Nonsense, Bright Light

  • Familiarity: I gave it as a gift but have feedback to share

I gave this to my girlfriend and this is what she had to say: "This headlamp is great if you're looking for a no nonsense, bright light. It doesn't have a lock or a blinking light but it will do that trick in the dark. It's also light weight and I love the bright blue color, makes it easy to find around the camp site! If you're looking for a fancy headlamp, this is not the headlamp for you. If you're looking for something in the cheaper price range that will light your way, however, this is it!"
