Maintenance
Cleaning
To clean the CL20R, wipe it with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these may damage the finish or internal components.
Water and Dust Resistance
The CL20R is rated IP54 for water and dust resistance, meaning it is protected against dust ingress and splashing water from any direction. While durable, avoid submerging the light in water.

Troubleshooting
- Light not turning on: Ensure the battery is charged. If operating via USB-C, confirm the cable is securely connected and the power source is active.
- Short battery life: Battery life can vary based on brightness mode. High brightness consumes more power. Ensure the light is fully charged before use.
- Light not charging: Check the USB-C cable and power adapter. Ensure the light is turned off for optimal charging.
- Light output reduced when plugged in: This is normal behavior for continuous operation. The light operates at a reduced level to prevent overcharging and allow for continuous use.
