Exposure Lights - Sirius mk11

Introducing the Sirius 11, the ultimate companion for your daily rides and the perfect fusion of output, weight, and endurance. Every element of the 11 has been meticulously engineered to deliver unmatched performance for riders who demand the very best.

Powered by next-generation battery technology and an upgraded PCB design, the 11 pushes performance boundaries even further. The light now delivers a powerful 1300 lumens of output and an impressive 130-hour maximum runtime, so you can ride for weeks without needing to recharge. When it’s time to power up, USB-C fast charging gets you back on the road in just over two hours, compatible with most modern power banks for ultimate convenience on the go.

Various programs in the lights can easily be selected to offer a choice of run times and modes so you can find the right one for your ride, be it an all-night adventure or an intense blast.

Patented circuitry within the light will reduce power to the LEDs, if they go beyond the optimum temperature, keeping the light as efficient as possible to maximise output and battery capacity. Once the light has cooled, the power is automatically restored.
