The Quad Industrial Headlamp is UL Rated for class I and II Division 2 and is the lightest in Princeton Tec’s line of regulated-LED headlamps. Four Ultrabright LED s power through the darkest conditions and the LEDs are forever safe inside a tough waterproof housing that will survive severe impacts and water submersion up to 1 meter. The wide beam of the 4 operation mode switch make it a perfect light source for almost any job. Weight conscious users will love the Quad’s sophisticated circuitry that allows the use of lithium AAA batteries. They reduce the Quad’s weight to 82 grams, perform in extremely cold temperatures, and significantly increase regulated burn times.
