The ReFuel is a reintroduction to the classic Princeton Tec Fuel headlamp featuring a significant lumen upgrade thanks to new surface mounted LEDs. Other upgrades? A painstakingly reengineered battery door featuring sturdier components with a larger lip for easier access, as well as the ability to fine tune your light output with the new dimming feature. The ReFuel is extremely simple to use and takes advantage of a clever asymmetrical single arm bracket. This design makes directing the light effortless and reliable once on your head. The large, easy to find button controls on/off and with a press and hold, dims the light to your preferred output. Refreshed and Reengineered, the ReFuel is ready to reconnect you to the great outdoors.All Princeton Tec products have been designed, manufactured, and assembled in their New Jersey workshops for over 40 years.POWER: 200 LumensLAMP: 4 White Ultrabright LEDsBURN TIME: 75.5 hours (flood low), 3 hours (flood high)MAX BEAM DISTANCE: 21 metersBATTERIES: 3 AAA Alkaline (included)WEIGHT: 2.8oz / 78gWATER RESISTANT: IPX4 (splashing water)WARRANTY: 5 YEAR
