Compact, feather light and full of features, the Princeton-Tec Quad headlamp is a great LED backcountry companion. The Quad has 3 power settings (high, medium and low) and an emergency blinking mode. Each power setting provides true current regulation, ensuring that the Quad will remain at constant brightness as long as the batteries have sufficient voltage.
The large, single switch design makes the Quad easy to operate. The lamp rotates 90 degrees to provide convenient illumination regardless of the situation.
On high, the Quad's wide, 4 LED bulbs throw a beam up to 78.7 ft. The medium and low settings cast beams up to 59 ft. and 39 ft., respectively. With Alkaline batteries, run time on the high setting is 50 hours (1 hour at constant brightness). The low setting provides a run time of 150 hours (24 hours at constant brightness).
The Quad is powered by three Alkaline AAA batteries (included). With these batteries, the Quad weighs a mere 3.4 oz. If you are looking to cut every possible ounce or want to increase burn time, the sophisticated circuitry of the Quad allows you to use more lightweight, high-performance lithium batteries in place of the standard Alkaline batteries.
The plastic housing of the Quad is waterproof to 1 meter and is extremely resistant to wear and tear.
The Princeton Tec Quad is available in your choice of colors.
