The Quad is the lightest of the PT regulated-LED headlamps. 4 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 1 meter.

The sophisticated circuitry allows the use of lithium AAA batteries which reduce the weight to 82 grams, perform well in extremely cold temperatures and significantly increase burn times.
