Beam quality
Beam quality
Aside from the various beam patterns, it is important to check their uniformity. Whatever the pattern, the beam of a Petzl headlamp is always uniform and therefore comfortable.
The quality of the beam is dependent on that of the LEDs and of the optics' design. The latter is complex and requires the knowledge of an optical engineer. Petzl chose long ago to integrate these skills into its research and development teams and equipped their lamps with the highest-quality components.
