Iota Headlamp Brightness Memory

Iota Rechargeable Headlamp is rated 4.4 out of 5 by 18.
Rated 5 out of 5 by from Don't throw away any more batteries! Just charge this powerful headlamp via USB cord and have light for hours (or more on low). Really cool with the button configurations and the tap button ability. Very light and compact so should be taken on every bc outing. Also the strap is soft, comfy, and easy to adjust.

Rated 5 out of 5 by from Big Time Brightness, Small Time Portability Super-impressed with the brightness-to-size ratio of this smart little headlamp. Diffused beam casts more than enough light for night jogs or campsite adventures. Rechargeable feature makes it easy to top up the battery on the go with a travel charger. Plus, the small and lightweight design is great for the minimalist inclined.

Rated 5 out of 5 by from Big light at the end of a small tunnel..... Couldn't get over how bright the Iota is for its size, its super useful to be able to have a rechargeable lamp on those days when the battery draw is empty at home. Perfect for night trail runs and for a "emergency" headlamp on days when you think you won't be out late but always ends up that you do....

Rated 5 out of 5 by from Simply great! Awesome, lightweight, easy to use headlamp. I like the ReVolt for my more serious adventures, but I have one of these in each of my cars for unexpected illumination needs. They are small, compact, and are easy to keep charged with a micro USB cable in your car.

Rated 4 out of 5 by from Nature friendly Headlamp This lamp is really very smart. I like using it. However, I found a few drawbacks: - it can't shine while charging - the entrance for a charger is covered of course but not so much for protecting it after falling to paddle or to a river. I hope it will be fixed in the future. Make covering for charger hermetic increase water resistance and make much better.

Rated 5 out of 5 by from Great for around camp This is great for around camp or alpine starts but not great for finishing in the dark. The battery gives you about 2 hours of light strong enough to navigate off trail with then drops off to an intensity level more applicable for reading or following a trail. Small, light, rechargable, and inexpensive.

Rated 5 out of 5 by from Great little torch I have a couple of these. One in the BC pack, one in the truck, and one in the house. Stoked to not deal with batteries and have a great amount of light.

Rated 5 out of 5 by from Awesome headlamp for what it was intended for. I bought my Iota while I was in Zermatt when digging through my pack thinking I left my Revolt back in Chamonix. I just wanted a basic light and when the guy in the climbing shop showed me this one I knew it would get me through my time there. It is small, has a good battery life and just doesn't have all the other bells and whistles that my Icon and Revolt have, which I most of the time feel that I don't need those features. I just want a basic headlamp. This Iota is that animal. No batteries to mess around with and just a great little headlamp. As soon as I got to my spot I was poaching for a nights sleep in the woods above the Gornerschlucht Gorge. Yeah, there was my Revolt in the top lid of my pack. I still don't regret the purchase.
