Princeton Tec calibrates each collimator to the type of LED and application of each light. With proprietary optimized collimator / lens systems, Princeton Tec continues to advance LED technology.Specifications:Power: 130 LumensLamp: 1 Maxbright LEDBurn Time: 121 HoursBatteries: 3 AAA Alkaline or LithiumWeight: 105 GramsIdeal Uses:Road BikeMountain BikeWARNING: This product can expose you to chemicals including BISPHENOL A (BPA) which is known to the State of California to cause birth defects or other reproductive harm.
