When applied well, technology should be simple. Such is the case with the innovative Princeton Tec Fuel headlamp - designed to meet the widest range of applications while remaining small, lightweight and robust. With all of the touch points of the product being considered, the Fuel's smart design fulfills technology's promise of actually making our lives easier. What could be better than a light that weighs only 78g with 43 lumens of brightness and 146 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 3AAAs and its electronics. Yea.. that's pretty much it. Simple. Perfect. Fuel.
