2. Important Safety Information
Always follow these safety precautions to reduce the risk of fire, electric shock, or injury.
- Power Off: Always turn off the power supply at the switch and disconnect from the mains before installing, removing, or cleaning the bulb.
- Indoor Use Only: This product is designed for indoor use in dry environments. Do not use in wet locations or outdoors unless specifically rated for such use.
