This high-powered bike light features three high output LEDs for up to 1600 lumens of output. It has seven modes and our Tri-Focus Optics optimizes light output - this creates a brighter centre spot in a large wide-angle pattern. Its rugged machined aluminium construction features cooling fins and cut-outs for side visibility. The Super Drive 1600XXL is both Smart Wireless and Remote Switch compatible for additional ease of use. An Auto Day/Night Sensor automatically adjusts lumen output. The light is micro-USB rechargeable and it can run for up to a massive 148 hours on a full charge. A versatile strap secures it to a variety of handlebar sizes.
