Handyman's Helper

I can't give you an honest opinion about this light. I bought it and a second one to replace two much older headband lights which I purchased sometime around 2017-2018 (stopped holding a charge longer than a half hour). I use the headband lights for all sorts of things that require the use of both hands. I've been buying lights and battery packs from BioLite for 7 years now, maybe longer. Never had an issue with manufacturing defects.

Disappointed

This is my second BioLite headlamp. Have a previous version that has worked great for ~2 years now. I use it mostly for hunting/hiking purposes—wanted a second one for around the house. While it is still handy being a compact profile & plenty bright—this version seems to have an issue holding a charge. Have noticed now that each time I fully recharge it—even if only “idle” for a few days—it’s never at full charge the next time I pull it out. Not sure why, but it loses charge even while sitting idle/in storage. Have to say I’m disappointed considering how well the original version has performed.

Decent light, short battery

Battery life is pretty short but the light is good when it's charged up!

The only headlamp you'll ever need

Bright, reliable, and so light it doesn't bounce when I'm trail running. I could wear it all day and wouldn't notice. I love this headlamp! Biolite for life.

Comfortable and super bright. The battery life is ok, I was hoping it would be a bit longer, but loving it!

Good, but...

I am a little disappointed with the short battery life, only about two and a half to three hours. I do like how it switches to a dimmer setting to extend the time, I just wish this third, super-dim setting was an option I could choose so I could get five or six hours out of the charge.

Almost a great product..

No issues with the lamp itself, but the strap is very frustrating to adjust and really negates the purposefulness of the entire product. I’d recommend either upgrading to their other headlamp or purchasing elsewhere.

Battery life is an oxymoron with this device

I bought this in November 2023 as Christmas present. We use headlamps during the spring, summer and fall camping seasons. After a full charge The battery lasts for maybe 15 minutes before it becomes to dim to see. Heck a clear night with a full moon shined more light. I have a competing brand and for the amount we use it mine will last an entire week one one charge (it also charges in half the time of the billet despite a USB 2 and a micro USB connection.One trip from the campsite to the facilities pretty well drains the biolote rendering it useless
