The NiteRider® Lumina™ 750 Boost is the perfect light for mountain bikers, road riders, adventure riders and urban commuters. Featuring a proven design/ride tested handlebar strap mount that is sure to remain rock solid whether on the trail or pavement. Double clicking the power button activates Boost Mode, giving you the option to operate your light at 750 lumens maximum light output! This self-contained light makes use of the IntelliCharge™ function, which charges the battery twice as fast as the normal charge rate when connected to a higher amp AC adapter. With our custom engineered optics, the Lumina™ 750 Boost projects a beam pattern that provides a generous spot and wide flood beam pattern of 750 lumens!
