Safety Information
Always follow basic safety precautions when using electrical products to reduce the risk of fire, electric shock, and personal injury.
- WARNING: Turn off power at the circuit breaker or fuse box before installation, removal, or inspection.
- Do not use with dimmers unless specifically rated for CFL dimming. This lamp is not designed for use with dimmers.
- Do not use in totally enclosed fixtures as this may shorten lamp life.
- Avoid touching the glass portion of the lamp directly with bare hands. Use a clean cloth or gloves.
- If the lamp breaks, ventilate the room for 15 minutes. Carefully collect all broken pieces using stiff paper or cardboard and place them in a sealed plastic bag. Do not use a vacuum cleaner. Dispose of the bag according to local regulations for fluorescent lamps.
