From evening commutes to nighttime trail rides—Planet Bike's Blaze 650 XLR blasts the high output you need to see and be seen. It features a high-powered Cree LED that puts out a whopping 650 lumens of light. The Blaze powers up with a self-contained lithium ion battery that delivers 2.5 hours of light on the highest setting. There's also a medium 350-lumen mode, a low 25-lumen mode, and an attention-getting flash mode (6, 10.5, and 40 hours of run time respectively). The Blaze charges up in 6.5 hours with the included USB cable and weighs in at 128 grams. Plus, Planet Bike's included QuickCam bar mount makes for quick and easy on/off without tools.
