6. Maintenance and Safety
6.1 General Maintenance
- If you do not use the headlight for a long time, please charge it every three months to maintain battery health.
- Keep the light clean. Wipe with a soft, damp cloth as needed.
6.2 Safety Precautions
- Do not shine the light directly into eyes, as it can cause temporary vision impairment.

7. Troubleshooting
7.1 Intelligent Temperature Control
The headlight is equipped with a temperature measuring element. If the internal temperature exceeds 70°C, it will automatically downshift to a lower brightness mode to prevent overheating. If the lamp bead temperature exceeds 100°C, the light will automatically cut off power and shut down to protect the components.
7.2 Low Voltage Protection
When the battery power drops below 15%, the light will automatically limit adjustable modes to 400 lumens or 200 lumens to conserve power. If the battery voltage becomes too low, the light will automatically cut off power to protect the battery from deep discharge.
