2. Safety Information
Please read and understand all safety instructions before installing or operating this product. Failure to follow these instructions may result in electric shock, fire, or other hazards.
- Risk of Electric Shock: Always turn off power to the fixture at the circuit breaker or fuse box before installation, removal, or inspection.
- Non-Dimmable: This bulb is non-dimmable. Do not use with dimmer switches, as this can damage the bulb and void the warranty.
- Indoor Use Only: This bulb is designed for indoor use in dry locations. Do not expose to water or excessive moisture.
- Proper Fixture: Ensure the fixture is rated for the bulb's wattage and voltage (120V).
- Handle with Care: CFL bulbs contain a small amount of mercury. Handle with care and avoid breaking the glass. In case of breakage, follow proper cleanup procedures.
- Operating Temperature: Do not use in enclosed fixtures that restrict airflow, as this can shorten bulb life.
3. Installation
Follow these steps to safely install your Feit Electric CFL bulb:
- Turn Off Power: Locate the light fixture's power source and turn off the electricity at the circuit breaker or fuse box.
- Allow Cooling: If replacing an old bulb, allow it to cool completely before handling.
- Unscrew Old Bulb: Carefully unscrew the old bulb counter-clockwise from the socket.
- Screw In New Bulb: Gently screw the Feit Electric CFL bulb clockwise into the standard medium base (E26) socket until it is snug. Do not overtighten. Handle the bulb by its plastic base, not the glass spiral.
- Restore Power: Turn the electricity back on at the circuit breaker or fuse box.
4. Operation
Once installed, the Feit Electric ESL23TM/D/4 bulb operates like any standard light bulb. Simply use the wall switch or fixture switch to turn the light on or off.

- Frequent Switching: While durable, frequent on/off cycling can slightly reduce the lifespan of CFL bulbs.
5. Maintenance
These bulbs require minimal maintenance. For cleaning, ensure the power is off and the bulb is cool.
- Cleaning: Gently wipe the bulb with a soft, dry cloth. Do not use liquid cleaners or abrasive materials.
