Brightness or burn time: a question of balance
For a given quantity of energy, increasing the brightness automatically decreases battery life, and vice versa.
Example: to obtain 100 lumens of brightness for 50 hours, the equivalent of 75 AAA batteries would be required.
Petzl's solution: 3 lighting technologies
The ideal compromise between power and burn time
the headlamp supplies energy "directly" to the light source
• The headlamp has a very long burn time
• The headlamp lights very intensely for the first minutes, and then decreases gradually over time
• The rated brightness is the maximum light output, measured when the lamp is first turned on
Comfortable lighting that does not decrease over time
The headlamp has an integrated electronic regulation system.
• Constant brightness Brightness remains constant over a predetermined time.
• BOOST mode: allows occasional access to maximum brightness.
• Reserve lighting When the constant lighting phase ends, reserve lighting offers a weaker light output over several dozen hours, allowing the activity to be completed.
Powerful, self-adjusting lighting
A light sensor adapts the beam pattern and brightness of the headlamp instantly and automatically to the need.
• Optimized control of brightness and burn time
• Adapted, comfortable lighting:
- proximity lighting
- lighting for movement
- lighting for distance vision
• Manual operation is minimized
• Works with rechargeable battery
• Personalize your headlamp: OS by Petzl software
