1100 lumens. You can see up to 155 meters away. One button can control all functions such as ON/OFF, lighting mode, brightness and lock. Choose from two lighting modes: reactive lighting or standard lighting. REACTIVE LIGHTING mode provides longer burn time, better visual comfort and fewer manual operations. This allows the light sensor to automatically adjust brightness and beam pattern to optimize usage. Minimum burn time is 7 hours. Mixed beams meet the needs of high-performance lighting during outdoor activities: close or far viewing. Continuous red illumination maintains night vision and improves reading comfort. The red light is visible and strobes to let you know your location, especially in an emergency, without blinding those around you. Reflective headband keeps you visible at night. Only 100g. The ergonomic adjustable headband has a split construction for an ideal fit.
