Planet Bike blasts the night away with the Blaze 500 XLR. It features a high-powered Cree LED that puts out a whopping 500 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 low 250-lumen mode and an attention-getting flash mode (4.5 and 25 hours of run time respectively). The Blaze charges up in 5.5 hours with the included cable and weighs in at 128 grams. Plus, Planet Bike's included QuickCam bar mount makes for quick and easy on/off without tools.
