Petzl Nao 2 Headlamp
The Petzl Nao 2 Headlamp with REACTIVE lighting takes headlamp technology to a higher level with Petzl's brightest headlamp ever at 575 lumens. The Nao headlamp has rechargeable batteries and software that lets you tailor the Nao's brightness, burn times, and distance settings for specific conditions, plus create different “activity profiles.” Peer into the darkness to check on your buddy (or maybe scan the trail to the outhouse) and Petzl's Nao headlamp shines a bright, focused beam. Look down to fiddle with your gloves or glance at your map, and the Nao's sensors instantly adjust both the intensity and type of light shining from its LEDs. The Nao could make manually adjusting your headlamp between tasks a thing of the past, and those sensors even increase burn time by dimming the light when you don't need it. Petzl calls the technology “reactive lighting.” We call it the most high-tech headlamp we’ve ever seen.
Located right above the Nao 2's two LEDs is a sensor capable of measuring ambient light, and smart enough to adjust the beam strength and pattern according to the light conditions, specially aiming to give you the optimal amount of light without using up more battery power than necessary. For instance, if you happen to look right ahead on a dark, moonless night, the Nao 2 is capable of shining your path with a high-power, long-distance beam. Should the situation change and you feel lost, pulling out the trekking map from your pocket to go over it, it will cast a wide, low-power beam. This means you get to enjoy the right amount and type of light you need, without having to fiddle around with certain kinds of adjustments to achieve such an effect.
Petzl's REACTIVE Lighting technology will replace the current headlamps with "declining" mode and "constant" mode. The declining mode type maximizes a headlamp’s burn time through the gradual lowering the amount of light output, and as light output decreases over time, declining-mode devices will deliver the least amount of light in the darkest conditions. With constant mode, a constant light output sounds great, but it is drains your batteries. Reactive Lighting merges both strategies in a single solution, offering the right amount of light as and when you need it.
The Petzl Nao 2 Headlamp is featured in Outside Magazine's Essential Gear Guide. Says Outside Magazine: "Who says you have to take off your gloves to adjust your headlamp? Sensors in the Nao 2 automatically adjust the amount of light to what you’re looking at."
