Sirius 11 Headlight

What Our Gearhead® Experts Are Saying:

"I’ve compared the Sirius 11 against other premium commuter and all-road lights, and the weight-to-output ratio really stands out. It’s noticeably lighter than similar-output competitors, yet just as tough. The side visibility and fast USB-C charging give it a real edge for daily use."

In the crowded category of high-output bike lights, the Sirius 11 Headlight separates itself by delivering real-world performance in a lighter, more refined package. Exposure focuses on efficiency—pairing a powerful Cree LED with precise optics to maximize usable light rather than just raw numbers.

Compared to bulkier competitors, the Sirius 11 offers a focused 8° beam for distance vision while adding 270° side illumination that many trail-focused lights overlook. This makes it especially effective for commuters and mixed-terrain riders who need to be seen as much as they need to see. USB-C PD charging further boosts usability, cutting charge times and allowing convenient power-bank recharging on longer trips.

Durability rounds out the competitive picture. An IK09 impact rating, IP67 waterproofing, and a CNC-machined aluminum body put the Sirius 11 on par with the toughest lights in its class—without the weight penalty. For riders looking for a lightweight, high-output headlight that excels in both visibility and reliability, the Sirius 11 holds its own against top-tier alternatives.
