Exposure Lights Sirius 11 front lighting

Designed and manufactured in the UK by Exposure Lights, the Sirius 11 strikes the perfect balance between performance, weight and battery life for daily commutes, road rides or city travel. With 1,300 lumens delivered by a Cree XHP35.2 LED and an 8° collimated beam, it offers exceptional long-range illumination whilst ensuring 270° lateral visibility thanks to its specialised lens. Its CNC-machined 6063 aluminium body, hard-anodised in gunmetal grey, weighs just 90 grams and is highly resistant to impact (IK09) and water (IP67).

Next-generation battery technology combined with intelligent thermal management provides a runtime of up to 130 hours, depending on the selected mode. Nine modes allow for precise adjustment of brightness and runtime to suit your needs. Ultra-fast USB-C charging (approximately 2 hours), powerbank compatibility, DayBright mode for daytime visibility of over 1 km, and a simple single-button interface make this a reliable, durable light, ready for all conditions.
