Powered by 4 regulated Ultrabright LEDs* the QUAD delivers constant brightness on all modes in an ultralight waterproof housing**.

At a mere 96 grams, the Quad is the lightest in Princeton Tec's line of regulated-LED headlamps. Four Ultrabright LEDs power through the darkest conditions. The LEDs are safe forever 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 82 grams, 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, this light just may be smarter than you are.  3 AAA alkaline batteries included.  Lifetime warranty.

*Ultrabright LED - The highest quality LED available from Nichia, the Ultrabright LED is bright and efficient. The smooth, white, wide-beam light emitted by Ultrabright LEDs is ideal for close- to mid-range tasks. Ultrabright LEDs are usually grouped together to offer a more powerful light source. Advances currently underway will continue to improve the efficiency and brightness of Ultrabright LEDs.

**Waterproof Rating Level 2 - Princeton Tec's intermediate rating, Level 2, is assigned to lights that offer a degree of water protection equivalent to IPX7 in the International Electrotechnical Commission (IEC) standards. Lights rated at Level 2 provide waterproof integrity down to 1 meter for up to 30 minutes.
