With a consistent 800 lumens, you can ride safely. Additionally, the light intensity automatically adjusts based on your speed to extend battery life. When the sun sets while you're out on the trail, your ride doesn't have to end just yet. If your speed changes, the Varia UT800 will adjust accordingly. When paired with compatible Edge bike computers, the brightness is adjusted to ensure you have the right light for safe riding.

Thanks to its smart features, the Varia UT800 can be paired with compatible Edge computers that have light sensors. Once paired, the Varia UT800 helmet light automatically adjusts the light intensity based on speed and ride profile, providing more light when you ride faster while conserving battery at lower speeds. It also automatically adapts to ambient light and battery capacity, allowing you to stay out longer. You can turn the light on or off, control brightness, and more with a button press on the Edge computer or a dedicated remote.

With the Varia, adjusting the light intensity to match conditions is easy. The Varia UT800 helmet light offers five light modes: Power (800 lumens), Standard (400 lumens), Eco (200 lumens), Night Flash mode (100 to 300 lumens), and Day Flash mode (over 700 lumens). At full intensity, the light is visible during the day from up to 1.6 kilometers away.

The helmet light is compact and lightweight. It can be mounted on the helmet using the designated bracket and weighs less than 140 grams. Cyclists must comply with local laws regarding the placement of lighting while riding on the road. The Varia UT800 does not comply with the regulations of the StVZO.
