* Ultralight at 1.5 oz * 50 to 160 Hour Burn Time * 15 Lumen Brightness * 3 Light Levels + Flash * Water Resistant The innovative Princeton Tec Fuel Headlamp is designed to meet the widest range of applications while remaining small, lightweight and robust. With all of the touch points of the Fuel being considered, the design fulfills technology's promise of actually making our lives easier. What could be better than a headlamp that weighs only 2.7 ounces with 15 lumens of brightness and 160 hours of burn time? A light that also has an asymmetrical single arm bracket that makes directing the light effortless and reliable; a large, easy to find push button switch and a virtually bulletproof, easy access battery door that protects the 3 AAAs and its electronics. 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. Recognizing that different amount of light are needed for different conditions and situations, the Fuel is equipped with 3 brightness levels and a blinking emergency/signaling mode. 3 AAA Batteries are included.
