Overview: By CREE Q2 LED, to achieve fully comparable with the brightness of xenon halogen lamp, LED life of up to 10, 0000 hours, brightness up to 160 lumens Compared with the traditional LED, enhanced CREE LED can work in a more powerful current, & thus 1W, 3W high power LED that can be used in the headlamp 3W LED is so brightness that can easily achieve more than 10 hours of continuous illumination, which is brine xenon can not match Beam 3W CREE Q2 LED, plus a red beam LED; use three AAA batteries (Considering the transport regulation rules the batteries may not be included), it can works more than 10 hours
