Introduction
This manual provides essential information for the safe and effective use of your Sylvania CFL 2700K 100W Equivalent Soft White Light Bulbs, Model X21534. These compact fluorescent lamps (CFLs) are designed to provide energy-efficient illumination with a soft white light output, equivalent to a traditional 100-watt incandescent bulb while consuming only 23 watts.

Safety Information
- Power Off: Always turn off the power to the fixture and allow the bulb to cool before installing, removing, or cleaning.
- Handle with Care: Avoid touching the glass spiral portion of the bulb directly. Handle by the base to prevent damage and ensure a secure connection.
- Proper Disposal: CFLs contain a small amount of mercury. Dispose of bulbs according to local, state, and federal regulations. Do not dispose of in regular household trash.
- Non-Dimmable: These bulbs are not compatible with dimmer switches. Use with a dimmer switch may damage the bulb or the dimmer.
- Fixture Compatibility: Suitable for indoor use. For outdoor applications, use only in enclosed fixtures to protect the bulb from direct exposure to weather elements.
- Ventilation: Ensure adequate ventilation around the bulb to prevent overheating, especially in enclosed fixtures.
Setup and Installation
- Verify Power is Off: Before beginning installation, ensure the power supply to the light fixture is completely turned off at the circuit breaker or wall switch.
- Remove Old Bulb: If replacing an existing bulb, allow it to cool completely before carefully unscrewing it counter-clockwise from the socket.
- Inspect Fixture: Check the light fixture for any damage or loose wiring. Ensure the socket is clean and dry.
- Install New Bulb: Gently screw the Sylvania CFL bulb clockwise into the E26 medium base socket until it is finger-tight. Do not overtighten.
- Restore Power: Once the bulb is securely installed, restore power to the fixture at the circuit breaker or wall switch.

Operating Instructions
After installation, simply turn on the light switch to activate the Sylvania CFL bulb. These bulbs provide instant illumination, though they may take a few moments to reach full brightness, especially in colder environments. This is normal for CFL technology.

Maintenance
- Cleaning: To clean the bulb, ensure the power is off and the bulb is cool. Wipe gently with a soft, dry cloth. Do not use liquid cleaners or abrasive materials.
- Replacement: These bulbs have an average life of 10,000 hours. Replace bulbs when they begin to flicker persistently or fail to illuminate.
- Disposal: Follow the safety guidelines for proper disposal of CFL bulbs due to their mercury content. Contact your local waste management facility for specific instructions on recycling or disposal.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Bulb does not light | No power to fixture, loose connection, faulty bulb | Check circuit breaker/switch. Tighten bulb. Replace bulb if necessary. |
| Bulb flickers | Loose connection, incompatible dimmer (these bulbs are non-dimmable), end of life | Tighten bulb. Ensure no dimmer is used. Replace bulb if flickering persists. |
| Bulb takes long to reach full brightness | Normal operation for CFLs, especially in cold temperatures | Allow a few minutes for the bulb to warm up. This is expected behavior. |
