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 standout feature of 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. The sensor genuinely works, and once experienced in real fog, it's hard to want a headlamp without it. At $80 with 700 lumens, a USB-C rechargeable battery, and 2.9oz, it checks everything else too.

What Sets It Apart

Well suited to AT section hikes, early morning trail runs, and car camping alike. The moisture sensor earns its place specifically in fog or rain — the automatic switch to flood beam keeps visibility usable in conditions where a normal headlamp's spot beam would scatter and become nearly useless.

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 on unfamiliar terrain, a brighter headlamp in the 1000-plus lumen range is the better choice.

Does BioLite have a warranty?
