Iota Headlamp Brightness Memory

Iota Rechargeable Headlamp is rated 4.3 out of 5 by 23.
Rated 5 out of 5 by from Simple on/off, no extras I had one of these headlamps that lasted nearly 3 years. It broke. I chose to replace it because I like the on/off and not needing to cycle through other settings, and It's rechargeable which is a real plus. I use it nearly daily for a reading light as well as outdoor use.

Rated 5 out of 5 by from Great headlamp I purchased the Iota in 2017 to take as ultralight headlamp on a 21 day backpack on the JMT. I used it to summit Mt. Whitney on that trip and many days/nights. I have been very impressed with the battery life and the quality of the light. I recently used this headlamp to summit Mt. Baker. I love the size and ability to recharge.

Rated 4 out of 5 by from Small and pack-able This is not the brightest head lamp I own from BD, but it is the smallest, most pack-able, and it's rechargeable. If your looking for a good head lamp to keep in your pack for that just in case moment this is the one for you. It has plenty of light for dust and down trail runs.

Rated 1 out of 5 by from Great headlamp with a critical weakness I used this lightly around the house for a few months and on one three day camping trip. It worked great. Perfect, really. Then I brought it a a 5 day hike along the Pacific coast. Just those days in moist weather caused the two screws to rust and the plastic to crack that holds the lamp on the head-strap. The lamp cracked right off. I can't remember the lamp ever taking any hard hits or drops that would justify the crack.

Rated 5 out of 5 by from Buy It! Could not be more pleased with the performance of the Iota Headlamp. Has helped me see when performing home projects where the lighting sucks. Helps out during the pre-dawn dog walks.

Rated 5 out of 5 by from small and powerful This headlamp is always in my kit. The overall lamp is very small and easy to pack. The light is very bright and lasts a long time. I can forgot about this headlamp in my pack for over a month, and the charge is still full when I need it.
