With 430 lumens, the Duo Z2 offers high brightness. It is waterproof in freshwater up to 1 meter for about 30 minutes, battery-operated, and extremely robust. This makes it ideal for demanding outdoor sports (caving, orienteering, biking, etc.). To avoid blinding others, the Duo Z2 is equipped with Petzl's patented Face2Face glare protection feature, making group movement more comfortable. Depending on the need, users have access to five lighting modes. These range from a wide beam with low brightness and long duration to a boost mode for temporary access to the maximum brightness of 430 lumens. The lamp features a large, ergonomic switch that can be easily operated even with gloves. An electronic lock prevents accidental activation during transport and when the lamp is not in use. The battery housing worn at the back of the head creates a balanced weight distribution. When the battery is nearly depleted after a long trip, the Duo Z automatically switches to reserve mode.

In the Constant Lighting headlamps, the brightness remains consistent throughout the specified lighting duration. This brightness is below the maximum value when the lamp is turned on. After the lighting duration expires, the lamp automatically switches to reserve mode with reduced brightness.
