Product Features Dual Headlights designed specifically for sudden weather defective and harsh environments such as trail runs. The white light uses CREE XP-L2 V6 LED (5700K) for up to 1,100 lumens and a maximum illumination distance of 80 meters. Combined with orange peel reflectors for a uniform and soft light source and 100° illumination angle Warm light uses CREE XP-L V6 LED (3000K) up to 920 lumens and a maximum illumination distance of 117 meters. Crystal coating combined with Precision Digital Optical Technology (PDOT) provides long distances in rain, snow and fog. High efficiency constant current circuit ensures 18 hours of stable output. Equipped with 4 brightness levels and 2 special modes in either light source. Both LEDs can notify battery voltage (±0.1V) High performance temperature control function (ATR) built in (Patent No. ZL201510534543.6).
