BioLite HeadLamp 800 Pro Review (2026)

Name: BioLite HeadLamp 800 Pro
Brand: BioLite
Price: 80.00 USD
Availability: InStock
Rating: 9.4 (1 reviews)

The thing that got me on the BioLite HeadLamp 800 Pro is the moisture sensor. It sounds like a gimmick — a sensor that detects rain and automatically switches to a low-angle flood beam so you do not blind yourself with reflected light in fog or rain. But I have been caught in fog on the AT at night and the normal spot beam turns into a wall of white. The BioLite sensor actually works, and once you have used it in real fog you will not want a headlamp without it. At $80 with 700 lumens, a USB-C rechargeable battery, and 2.9oz, it checks everything else too.

Field Notes

Used this on two AT section hikes in Virginia, early morning trail runs in the Blue Ridge, and as the default headlamp for car camping. The moisture sensor earned its place on a night hike near Roan Highlands in October where we hit fog on the ridge — the automatic switch to flood kept visibility usable where a normal headlamp would have been nearly useless.

700 lumens with a moisture sensor that solves a real problem

Who This Is For

The BioLite HeadLamp 800 Pro ranks #1 of 4 in this category and is one of the strongest options in this category. It is well-suited for hikers and campers who want BioLite makes outdoor energy products with a genuine social mission. The HeadLamp 800 Pro delivers 700 lumens with a moisture sensor that automatically switches beam angle in rain or fog to prevent blinding reflection, and it performs best when used for the purpose it was designed around.

I review gear the way most people actually use it — weekend trips in the mid-Atlantic, day hikes on the AT, car camping in the Smokies and down at the Outer Banks. Not expedition use, not extreme conditions. Normal outdoor life for normal people, and occasionally with kids along who provide their own kind of honest product feedback.

Common Questions

What does the moisture sensor actually do?

It detects water droplets and automatically switches from spot beam to a low-angle flood beam that lights the ground without creating a white wall in fog. In real fog, this is a significant usability improvement.

Is 700 lumens enough for night trail running?

For familiar trails at moderate pace, yes. For technical trails at speed or unfamiliar terrain, I would want 1000-plus.

Does BioLite have a warranty?

2 years from purchase. BioLite customer service has been responsive in my experience.
