Great product

"This is a high quality product, I would rebuy!"

G. L. (5/5)

Gotta have it!

"This light has been my first headlamp purchase and I usually use magnetic tail lights for work but working on a jobs item were there is no lighting or power, this light is a must. I worked several weeks with no lighting inside a commercial building and I loved using it everyday. First off, I love the flood light as it illuminates a wide area which is perfect for small space manuvering or casual maneuvering. The 5,000MAH battery would last me average 8-10 hours of use on/ off but mainly on throughout my work and being a long time Fenix enthusiasts, having spare batteries let's you keep working. The light is also easily adjustable to center your light beam on your work area as well as simple and quick controls for your desired light. If I could use this everyday I would but thats why I also have EDC lights. Highly recommend this headlamp!"

HR70 headlamp repair

"I sent in my 2+ year old HR70 headlamp for free repair. Instead of repairing, they sent me a new one. Very happy!"

Couldn't live with JUST one

"I absolutely Love this headlamp. It took a little longer getting used to the weight of it and the much brighter red light vs the older version HM60. I originally bought one for work, but ended buying another for home. Fantastic headlamp! And then found out Fenix offers a veteran discount? Yes please!"

The Best Headlamp Ever

"This is my second headlamp and this one doesn't disappoint either. The first just wore out over a 10 year period of use and so far my new one is just as great as the first. It can virtually light up a full football field a head of me. The new headband seems to be of better construction not to say the first one wasn't of quality but this just feels better. The weight of it is still light enough to carry and wear without being a distraction and I love the new hidden battery recharge plug in that is hidden from the elements. The overall whole package of the light and brightness of it is just amazing."

Martin H. (5/5)

Worth it!

"I've been a fan of Fenix headlamps for a few years now. Headlamps get heavy use in our home and Fenix headlamps have held up well. Popular enough for our family that we ended up all unknowingly buying each other Fenix headlamps for Christmas!"

H M 70R Headlamp

"Awesome light for around the house and hunting afield. Long lasting battery and easy to control buttons after a few trips out."

Headlamp

"I purchased two of the HM70R rechargeable headlamps as gifts and they absolutely love them"

Laura S. (5/5)

Affordable MTN bike helmet light.

"Absolutely love it as a bicycling headlamp. Good for serious mtn rides or costume parades. I 3m taped it to a bmx helmet. Great run time and light modes. Sometimes its a little bothersome to go from spot modes to red/white flood modes, but it is wonderful for city rides and MTN bike trips even in rain. the red walking light is awesome for touring/gravel/camping and it can be aimed back for a red flasher if not needed at the time for a forward light. Run time is very good with many trips on 1 battery and a convenient spare in carry case. They also offer a top button version. Ill probably buy it too. I often use this w bike helmet for putting up shop tools at dark or doing chicken coop duties."
