Featuring 550 lumens of light in a waterproof design, the Princeton Tec Vizz Headlamp shines brighter and farther. With multiple light settings and durable construction, the Vizz is an ideal choice for adventures on and off the grid. Featuring regulated LEDs, which use a sophisticated regulating circuit that maintains initial brightness as long as the batteries have sufficient voltage. One MaxBright LED creates a powerful spot beam for longthrow illumination (up to 85 meters). Light settings include spot high and low, white floodlight and red night vision, as well as dimming capabilities. IPX7 rating provides waterproof integrity when submerged down to one meter for up to 30 minutes. The impact-resistant, waterproof housing fits comfortably on your head using an adjustable elastic headband. Powered by three AAA alkaline batteries (included). Lock the Vizz when not in use to conserve battery life. Battery power meter provides continuous feedback on the condition of the batteries.
