- Ensure the bulb is properly installed in a compatible fixture.
- Turn on the light switch connected to the fixture. The bulb will illuminate.
- To turn off the light, simply flip the switch to the off position.

Maintenance
Feit Electric CFL bulbs require minimal maintenance:
- Cleaning: Ensure the power is off and the bulb is cool before cleaning. Wipe the bulb with a soft, dry cloth. Do not use liquid cleaners or abrasive materials.
- Replacement: When the bulb reaches the end of its lifespan (approximately 8,000 hours), it will cease to function. Replace it following the "Setup and Installation" steps.
- Disposal: Due to the small amount of mercury contained in CFL bulbs, they should not be disposed of in regular household trash. Consult your local waste management authority for proper recycling or disposal procedures.
Troubleshooting
If your Feit Electric CFL bulb is not functioning as expected, consider the following:
- Bulb does not light up:
- Ensure the power switch is in the "ON" position.
- Check if the bulb is securely screwed into the socket.
- Verify that the circuit breaker for the fixture has not tripped.
- Test the bulb in another working fixture to confirm if the bulb or the fixture is faulty.
- Confirm the fixture is not connected to a dimmer switch, as this bulb is non-dimmable.
- Bulb flickers:
- Ensure the bulb is fully screwed into the socket.
- Flickering can occur if the bulb is used with a dimmer switch or in an incompatible fixture.
- Flickering may also indicate the bulb is nearing the end of its lifespan.
