How Petzl Reactive Lighting Works
The self-adjusting light
The integrated light sensor is oriented in the same direction as the eyes; it measures and analyzes reflected light in order to instantly and automatically adjust the headlamp's beam pattern (wide and/or focused) and light output to the user's needs. This means the user gets an ideal amount of light without the need for constant manual adjustment. The self-adjustment also saves power when it's not needed resulting in longer battery life.
|For proximity lighting
When looking at an object at close range, for example when reading a map, tying a knot or setting up a tent, the beam is very wide and less powerful. Lighting adjusts automatically to the distance of the object.
When walking, running, etc., the beam is wide and has medium strength in order to illuminate obstacles in the path.
|For distance vision
When raising the head to see into the distance, looking for a trail marker or an anchor on a climb, for example, the light output increases and becomes more focused.
Other benefits of self-adjusting Reactive Lighting
You can focus on the activity and allow the NAO to make sure you have the light you need what you're looking at - no straining to see into the darkness or squinting because you're dazzled. You always have the right amount of light without needing to adjust the lamp.
Longer battery life because the light is reduced to only what you need, less power is wasted and battery life is extended.
|The lighting adjusts automatically to the changing need for light output and beam size. The average power consumption drops and so extends the battery life between recharging cycles.||With lighting set at constant, high light output is maintained for the life of the battery charge. This is useful if the application demands full power or a constant high level of light. At the end of the battery power, lighting drops significantly.|
