Product Overview
The Satco S9920 is a 2.5 Watt Dimmable LED C11 Light Bulb designed to provide warm white illumination equivalent to a 25-watt incandescent bulb. Featuring a candelabra (E12) base, this energy-efficient LED bulb is suitable for various fixtures requiring a smaller base type. Its clear finish and filament-style LEDs offer a traditional aesthetic while providing modern energy savings.

Setup and Installation
Follow these steps for safe and proper installation of your Satco S9920 LED light bulb:
- Safety First: Before installing or replacing any light bulb, ensure the power to the fixture is turned OFF at the circuit breaker or wall switch.
- Allow Cooling: If replacing an old bulb, allow it to cool completely before handling to prevent burns.
- Unscrew Old Bulb: Carefully unscrew the old bulb by turning it counter-clockwise. Dispose of old bulbs according to local regulations.
- Insert New Bulb: Gently screw the Satco S9920 LED bulb into the candelabra (E12) socket by turning it clockwise until it is snug. Do not overtighten.
- Restore Power: Once the bulb is securely installed, restore power to the fixture.
- Test: Turn on the light switch to confirm the bulb is functioning correctly.
Important: This bulb is designed for indoor use in dry locations unless specified otherwise by the fixture. Ensure the fixture's wattage rating is compatible with the bulb's 2.5W consumption.
Operating Instructions
The Satco S9920 LED bulb operates like a standard light bulb once installed. It is dimmable, allowing for adjustable light output when used with compatible dimmer switches.
- Standard Operation: Simply use your existing wall switch to turn the light on or off.
- Dimming Functionality: If connected to a compatible dimmer switch, adjust the dimmer control to achieve the desired brightness level. For optimal performance and to avoid flickering or buzzing, use LED-compatible dimmer switches. Consult your dimmer switch manufacturer's instructions for specific compatibility.
This bulb is designed for 120 Volts AC power supply.
Maintenance
LED bulbs generally require minimal maintenance. Follow these guidelines to ensure longevity and optimal performance:
- Cleaning: Before cleaning, ensure the power to the fixture is off and the bulb has cooled. Wipe the bulb with a soft, dry, lint-free cloth. Do not use liquid cleaners or abrasive materials, as they may damage the bulb's surface or internal components.
- Handling: Handle the bulb by its base, not the glass envelope, to avoid transferring oils from your skin, which can affect performance or appearance over time.
- Storage: If storing unused bulbs, keep them in their original packaging in a cool, dry place to protect them from damage.
