Brightness: the shape of the beam directly affects lighting distance

Lighting distance depends directly on brightness, but mainly on the shape of the beam. In fact, given the same brightness, lighting distance will vary depending on the shape of the beam.

Petzl indicates the different lighting modes available for each headlamp. These modes correspond to specific conditions of use: close-range work, moving around, seeing at a distance.

Optimized lighting performance: REACTIVE LIGHTING®

Brightness varies according to the user s need. Intelligent lighting optimizes battery life, offering longer burn time.

Prioritizing guaranteed brightness over time: CONSTANT LIGHTING Brightness stays constant as the batteries drain. When the batteries are almost drained, the headlamp switches automatically to reserve lighting, providing reduced brightness with longer burn time.

Example of REACTIVE LIGHTING®

Example of CONSTANT LIGHTING

Example of STANDARD LIGHTINGPrioritizing burn time: STANDARD LIGHTING Brightness decreases gradually as the batteries are drained. It is the most common technology.

Brightness and burn time are two inextricably linked parameters of any headlamp, regardless of its lighting technology. For a given quantity of energy, increasing the brightness automatically decreases burn time, and vice versa.

Prioritizing brightness over burn time

A question of balanceChoosing a Petzl headlamp means selecting a work tool designed to withstand the most severe conditions of use while providing maximum reliability:

Brightness and Burn TimePetzl Quality

Petzl headlamps provide maximum visual comfort for the user: lighting is uniform and has no bright point in the center, no spotting, no dark areas. Each batch of LEDs is tested and selected according to proper color homogeneity, low energy consumption, and high luminous flux. Each Petzl headlamp is individually inspected before leaving the factory. These operations include a test to measure lighting performance and beam homogeneity with the help of a digital camera.

Petzl has chosen to present information in its product instructions about the risks to the eyes associated with LED lighting. For this, the company uses the IEC 62778 and EN 62471: 2008 standards, Photobiological safety of lamps and devices using lamps. This standard classifies lamps according to risk groups.

The risk groups are as follows: - Risk group 0: no risk - Risk group 1: low risk. The product presents no risk related to exposure limits under normal usage conditions - Risk group 2: moderate risk. The reflex to look away from the lamp suffices to reduce the risk

Each model must pass particularly stringent tests: - For shock resistance, fall resistance, and crushing (including at low temperatures) - For functional reliability (mechanical endurance) - Individual inspection and test at the end of the assembly line (final quality check) - For water resistance

Consideration of photobiological risk

Testing from design to manufacturing

Presence of visual defects: lack of precision, discomfort, fatigue

Presence of a central bright spot: blinding

Perfectly uniform beam: user comfort
