You can use REACTIVE LIGHTING or STANDARD LIGHTING mode, depending on your activity or usage.
Warnings
- Carefully read the Instructions for Use used in this technical advice before consulting the advice itself. You must have already read and understood the information in the Instructions for Use to be able to understand this supplementary information.
- Mastering these techniques requires specific training. Work with a professional to confirm your ability to perform these techniques safely and independently before attempting them unsupervised.
- We provide examples of techniques related to your activity. There may be others that we do not describe here.
How to check which mode is active on your lamp:
1. Find the light sensor on the lamp (this information is found in the Instructions for Use or the product sheet for the lamp, at petzl.com).
2. In a dark area, point the lamp’s beam at the ground.
3. With the DUO RL, NAO RL and SWIFT RL lamps before 2026, you can use your finger to cover the sensor. With the SWIFT RL lamp after 2026, you should use a dark, opaque material to cover the sensor (e.g. headlamp headband).
4. If the lamp gets brighter, it is in REACTIVE LIGHTING mode. If the brightness level doesn’t change, it is in STANDARD LIGHTING mode.
To change modes, see the Instructions for Use for the lamp.
