- Heat Dissipation: The aluminum alloy housing is designed for efficient heat dissipation. Ensure the light is not covered or obstructed to allow proper airflow and prevent overheating.
- Cable Inspection: Periodically check the power cord and plug for any signs of damage. If damage is found, discontinue use and contact customer support.
