* Ultralight at 2.1 oz * 4 Ultrabright LEDs * Waterproof to 1 Meter * 3 Light Levels * Batteries Included At a mere 2.1 ounces, the Princeton Tec Quad is the lightest in Princeton Tec's line of regulated-LED headlamps. Four Ultrabright LEDs power through the darkest conditions. The LEDs are protected inside a tough waterproof housing that will survive severe impacts and water submersions up to one meter. The wide beam of the Quad is perfect for tasks around camp and is bright enough for technical scrambles and brisk runs on dark trails. 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 2.9 ounces, perform in extremely cold temperatures, and significantly increase regulated burn times on all modes. Equipped with regulated LEDs that maintain constant brightness and a battery power meter. An adjusting pivoting head shines light where you need it, and the durable ultralight strap provides plenty of adjustment for the perfect fit. Self-contained battery system eliminates external wires. Recongnizing that different amount of light are needed for different conditions and situations, the Quad is equipped with 3 brightness levels and a blinking emergency/signaling mode. 3 AAA Batteries are included.
