Tactikka Plus 2 headlamp Petzl

• Lighting performance according to ANSI protocol (American National Standard Institute):



Petzl follows the ANSI/PLATO FL 1 protocol to measure and communicate on the lighting power and the autonomy of its headlamps. This approach allows you to easily compare the performance of the various models of headlamps from Petzl and other manufacturers who adopt this protocol, using the same benchmark.

• Lighting power (in lumens)

This measurement is carried out between 30 seconds and 2 minutes after lighting the lamp. It indicates the maximum power emitted, with new cells or batteries, when the lamp is started.

• Lighting distance (in meters)

This is the maximum distance between the lamp and the place where only 0.25 lux of illumination remains. The measurement is carried out on ignition with new cells or batteries. The lighting distance depends directly on the lighting power, but above all on the shape of the beam.

• Autonomy (in hours)

It corresponds to the duration during which the lighting is optimal, from the ignition of the lamp until reaching 10% of the maximum power. Below this power, we switch to the "lighting reserve" phase.

• The lighting reserve (in hours)

The lighting reserve guarantees minimum operating or safety lighting.
