Bright, rechargeable and self contained—Planet Bike's Blaze 180 is a commuter's dream. It features a high-powered Cree LED that puts out 180 lumens of light. The Blaze powers up with a self-contained lithium polymer battery that delivers 2 hours of light on the highest setting. There's also a low 100-lumen mode and an attention-getting flash mode (4 and 25 hours of run time respectively). The Blaze charges up in 3 hours with the included cable and weighs in at 89 grams. Plus, Planet Bike's included QuickCam bar mount makes for quick and easy on/off without tools.
