Designed for technical rescue and worksites, the DUO RL rechargeable headlamp provides 2800-lumen brightness. With its REACTIVE LIGHTING® technology, a sensor analyzes the ambient light and automatically adjusts brightness to user requirements. Manual operation is minimized and burn time is optimized, so the user can remain focused on the activity. The aluminum lamp body provides excellent impact resistance. The DUO RL is waterproof and ideal for use in wet environments.
