Casting 1100 lumens at a weight of only 100 g, SWIFT RL is the ultimate multi-sport headlamp for all your outdoor activities. Using REACTIVE LIGHTING® technology, a sensor analyzes the ambient light and automatically adjusts brightness to your needs. The headband is reflective to remain visible at night. Its split construction gives you excellent stability during dynamic and intense activities such as mountaineering, trail running, and skiing. SWIFT RL is intuitive to use, with a single button that easily controls all functions: ON/OFF, lighting modes, brightness, and locking. If necessary, you can also use the continuous or strobe red lighting. It is rechargeable, with a five-level gauge that allows you to monitor the battery charge level.
