Introduction
Welcome to the instruction manual for your Feit Electric PL18AB/H/CCT/LED 4-pin Color Selectable PL Lamp. This manual provides essential information for the safe and efficient installation, operation, and maintenance of your new LED lamp. Please read these instructions thoroughly before installation and retain them for future reference.
This LED lamp is designed to upgrade existing fluorescent fixtures to energy-efficient LED technology. Featuring a 4-pin base, it serves as a horizontal replacement for traditional downlight fluorescents, offering selectable color temperatures of 2700K (Soft White), 3500K (Neutral White), and 4000K (Cool White).
Safety Information
WARNING: Risk of Electric Shock. Always disconnect power at the circuit breaker or fuse box before attempting any installation, maintenance, or removal of the lamp. Failure to do so may result in serious injury or death.
- This lamp is not intended for use with dimmers.
- Do not use this lamp in emergency exit fixtures or emergency lighting applications.
- Ensure the fixture is compatible with the lamp's voltage (120-277V) and wattage.
- If rewiring is required for ballast bypass, it must be performed by a qualified electrician in accordance with all applicable electrical codes.
- Do not modify or disassemble the lamp. There are no user-serviceable parts inside.
IMPORTANT NOTE REGARDING BALLAST COMPATIBILITY: The product offers flexible installation options, including direct plug-and-play with an existing ballast or direct wire operation after bypassing the ballast. However, user feedback has indicated potential issues when used with certain ballasts, including a risk of ballast failure. While the manufacturer states dual-mode capability, it is strongly recommended to consult a qualified electrician for installation, especially if choosing the rewiring option to bypass the ballast, or if you are unsure about the compatibility of your existing ballast.

Setup and Installation
Always ensure power is disconnected at the circuit breaker before beginning any installation. This lamp offers two installation methods:
Method 1: Plug-and-Play (with Existing Ballast)
- Disconnect Power: Turn off power to the fixture at the circuit breaker.
- Remove Old Lamp: Carefully remove the existing fluorescent lamp from the fixture.
- Check Ballast Compatibility: Ensure your existing ballast is compatible with LED PL lamps. Refer to the ballast manufacturer's specifications if unsure.
- Install LED Lamp: Insert the Feit Electric PL18AB/H/CCT/LED lamp into the fixture's 4-pin socket, ensuring it is securely seated.
- Restore Power: Turn power back on at the circuit breaker.
Method 2: Direct Wire (Ballast Bypass)
WARNING: This method requires electrical wiring knowledge. If you are not comfortable with electrical work, consult a qualified electrician. Improper wiring can lead to electric shock, fire, or damage to the lamp and fixture.
- Disconnect Power: Turn off power to the fixture at the circuit breaker.
- Remove Old Lamp and Ballast: Carefully remove the existing fluorescent lamp. Then, locate and remove the existing ballast from the fixture.
- Rewire Fixture: Bypass the ballast by directly connecting the fixture's lamp holder to the main power supply (120-277V). Ensure proper polarity (line and neutral) is maintained according to electrical codes. All unused wires should be capped.
- Install LED Lamp: Insert the Feit Electric PL18AB/H/CCT/LED lamp into the rewired fixture's 4-pin socket, ensuring it is securely seated.
- Restore Power: Turn power back on at the circuit breaker.
Operating Instructions
The Feit Electric PL18AB/H/CCT/LED lamp features an integrated switch for selecting your preferred color temperature.
- Locate the Switch: The color selection switch is located on the base of the lamp.
- Select Color Temperature: Before or after installation (if the switch is accessible), slide the switch to choose one of the three available color temperatures:
- 2700K: Soft White (warm, inviting light)
- 3500K: Neutral White (balanced, natural light)
- 4000K: Cool White (bright, crisp light)
- Power On: Once the lamp is installed and the desired color temperature is selected, restore power to the fixture. The lamp will illuminate at the chosen setting.
Note: This lamp is non-dimmable. Do not attempt to use it with dimmer switches.
Maintenance
Your Feit Electric LED lamp requires minimal maintenance.
- Cleaning: Ensure power is disconnected before cleaning. Clean the lamp with a soft, dry cloth. Do not use liquid cleaners, abrasive materials, or solvents, as these may damage the lamp's finish or internal components.
- No User-Serviceable Parts: The lamp contains no user-serviceable parts. Do not attempt to open or repair the lamp yourself.
Troubleshooting
If you encounter issues with your Feit Electric PL18AB/H/CCT/LED lamp, please refer to the following troubleshooting steps:
- Lamp Does Not Illuminate:
- Verify that power is supplied to the fixture. Check the circuit breaker.
- Ensure the lamp is correctly and securely seated in the 4-pin socket.
- If using the plug-and-play method, confirm the existing ballast is functional and compatible. A failing ballast may prevent the lamp from lighting.
- If using the direct wire method, verify all wiring connections are secure and correct.
- Check the position of the color selection switch on the lamp.
- Lamp Flickers:
- For plug-and-play installations, flickering may indicate an incompatible or failing ballast. Consider bypassing the ballast (professional installation recommended) or replacing the ballast.
- For direct wire installations, check for loose wiring connections or improper voltage.
- Incorrect Color Temperature:
- Ensure the color selection switch on the lamp is set to your desired position.
If these steps do not resolve the issue, please contact customer support or consult a qualified electrician.
