Automatic Light Intensity

The faster you go the brighter Varia UT 800 will be, watch out for those hazards at higher speeds. When connected with a compatible Edge cycling computer, GPS speed is used to automatically adjust the intensity of the headlight’s beam. At 800 lumens the Varia UT 800 is certainly bright enough at higher speeds for obstacles that may be in your path. Additionally, at lower speeds, the intensity of the light is lowered to conserve battery life. Day or night, road or trail - it’s time to step up to a smarter bike light.

See the Light The smart capabilities of the Varia UT800 allow you to pair it to compatible Edge computers with light sensors. Once paired, Varia UT800 automatically adjusts its beam intensity based on speed and ride profile so you get more light when you’re riding faster while conserving battery power at slower speeds. It also automatically adjusts to ambient light conditions and battery capacity to extend your ride, and it only takes a simple touch of your Edge computer or a dedicated remote to turn your lights on or off, control brightness and more.

Versatile Visibility Varia makes it easy to tailor your light output to the conditions. Varia UT800 features 5 light modes, including high (800 lumens), medium (400 lumens), low (200 lumens), night flash (100 to 300 lumens) and day flash (more than 700 lumens). At full power, it’s visible in daylight from more than 1 mile (1.6 km) away.

Ready to Ride The Varia UT800 smart headlight features a low-profile, lightweight design that attaches to your handlebar with out-front mount or to your helmet with a helmet or friction mount2, and it weighs less than 140 grams.
