The Bell lumina light series is our brightest option - perfect for the rider who wants to "see and be seen" in low light conditions. Lumina lights utilize advanced lens designs and reflector optics, along with brighter, flat LED technology to light up the road ahead of you while their diffused beam pattern makes you more visible to traffic and other riders. Our standard lumina 300 compact headlight easily installs without tools and uses 3 AAA batteries. The lumina 300 is small but powerful, and provides a strong, focused beam to see the road. And because all Bell lights are tested and rated to industry-recognized fl-1 standards, you can rest assured they perform as advertised. Headlight specifications: brightness: 50 lumens; run time: 22 hours (steady)/83 hours (flash) beam distance: 82 feet.
