Garmin Varia UT800 Smart Headlight

The Varia UT800 is a high-intensity smart cycling headlight built for urban streets and trails alike. Visible in daylight from over 1 mile (1.6 km) away, it blasts 800 lumens and intelligently adapts to your speed, ride profile, and ambient light — so you always have the right amount of light without draining your battery.

Smart Adaptive Lighting

Pair the UT800 with compatible Garmin Edge® cycling computers to unlock full smart control. The light automatically adjusts beam intensity based on your speed and ride profile — more lumens when you're pushing hard, conserved power at slower speeds. It also responds to ambient light conditions and remaining battery capacity to maximise your ride time up to 4 hours.
