Significantly lighter than its older sibling, the Pro 3600, the NiteRider Pro 2200 Enduro packs a ton of light into a dual beam design for serious MTB riders who want excellent night visibility on the trail. 6 Cree LEDs achieve up to 2200 lumens of blazing light with runtimes topping out at 36 hours. Borofloat lens and new triple reflector illuminate everything directly in front of you, in addition to the surrounding area. Six light settings provide 2-6 hours of steady runtime, plus there's Race, Walk and Flash modes for safety. Li-Ion battery is 2/3 the size of the battery in the Pro 3600 and recharges on the bike, thanks to the QR battery system. 8 Step Fuel gauge indicates when power is low and 6 Hour Smart Charger with QR battery system recharges the Li-Ion battery on the bike. Mount it to your helmet or handlebars and get ready to hit the trail!
