The Exposure Sirius 11 is a compact 1300 lumen front light for road, commuting and gravel riding. Its 8° collimated spot lens concentrates light for long throw, and a Day Bright pulse pattern keeps the rider visible in daylight from over a kilometre away. Nine programs let riders balance output against runtime, with up to 130 hours available.
The 90 g body is CNC machined from 6063 aluminum and hard anodized in gunmetal grey, with a stainless steel function button. It carries IP67 and IK09 ratings and uses Intelligent Thermal Management to protect the LED. USB-C charging takes just over two hours, and a single press while off shows battery level in a traffic-light format.
