Setup and Installation
This compact fluorescent lamp is designed for indoor use with compatible fixtures. Ensure the power to the fixture is turned off at the circuit breaker before installation to prevent electrical shock.
- Power Off: Locate the circuit breaker controlling the light fixture and switch it to the OFF position. Verify power is off by attempting to turn on the light switch.
- Remove Old Lamp (if applicable): If replacing an existing lamp, allow it to cool completely before handling. Gently twist and pull the old lamp from its base. Dispose of old fluorescent lamps according to local regulations, as they contain small amounts of mercury.
- Insert New Lamp: Align the 4 pins of the Sylvania 20668 lamp with the corresponding slots in the fixture's base. Gently push the lamp into the base until it is securely seated. Do not force the lamp, as this may damage the pins or the fixture.
- Restore Power: Once the lamp is securely installed, return to the circuit breaker and switch the power back ON.
- Test: Turn on the light switch to confirm proper operation.
Important: This lamp requires an electronic or dimming ballast for proper operation. Using it with an incompatible ballast may result in flickering, reduced lifespan, or failure.
Operating Instructions
The Sylvania 20668 compact fluorescent lamp operates like a standard light bulb once installed. It is controlled by the light switch connected to its fixture.
- Turning On/Off: Use the wall switch to turn the light on or off.
- Warm-up Time: Compact fluorescent lamps may require a short warm-up period (typically a few seconds) to reach full brightness, especially in colder environments.
- Dimming: If connected to a compatible dimming ballast and dimmer switch, the light output can be adjusted. Ensure the dimmer is specifically designed for CFLs or electronic ballasts.
Maintenance
Compact fluorescent lamps generally require minimal maintenance. Follow these guidelines to ensure optimal performance and longevity:
- Cleaning: Ensure the lamp is cool and the power is off before cleaning. Wipe the lamp gently with a soft, dry cloth. Do not use liquid cleaners or abrasive materials.
- Replacement: Replace the lamp when it reaches the end of its rated lifespan, or if it begins to flicker excessively, fails to illuminate, or shows signs of damage.
- Disposal: Due to the small amount of mercury contained in fluorescent lamps, proper disposal is crucial. Do not dispose of these lamps in regular household trash. Contact your local waste management facility or recycling center for information on proper disposal and recycling programs in your area.
