4. Setup and Installation
Proper installation is crucial for the performance and longevity of your E-Simpo G23 LED bulb. Please pay close attention to the ballast type in your existing fixture.
Ballast Compatibility:
- This LED bulb is compatible with inductance ballasts (magnetic ballasts) and can be used as a direct plug-and-play replacement.
- This LED bulb is NOT compatible with electronic ballasts. If your fixture has an electronic ballast, it MUST be bypassed before installing the LED bulb. Failure to bypass an electronic ballast will cause the bulb to flicker, smell, or burn out.
Installation Steps:
- Turn off Power: Before any installation, ensure the power to the fixture is completely off at the circuit breaker.
- Remove Old Bulb: Carefully remove the existing CFL PL-S bulb from the fixture.
- Identify Ballast Type: Determine if your fixture uses an inductance (magnetic) or electronic ballast. This may require opening the fixture.
- Installation for Inductance Ballast: If your fixture has an inductance ballast, simply insert the E-Simpo G23 LED bulb into the G23 socket. Ensure it is firmly seated.
- Installation for Electronic Ballast (Bypass Required):
- Locate the electronic ballast within the fixture.
- Disconnect the wires leading to and from the electronic ballast.
- Connect the two AC input wires (typically Line and Neutral) directly to the G23 lamp holder. This effectively removes the ballast from the circuit.
- Secure all connections with appropriate electrical connectors (e.g., wire nuts).
- Insert the E-Simpo G23 LED bulb into the G23 socket.
- Restore Power: Once the bulb is securely installed and wiring is complete (if ballast bypass was necessary), restore power at the circuit breaker.
- Test: Turn on the light switch to confirm the bulb is functioning correctly.

Warning: Bypassing an electronic ballast involves working with electrical wiring. If you are not comfortable performing this task, please seek assistance from a qualified electrician.
5. Operating Instructions
Operating the E-Simpo G23 LED bulb is straightforward:
- Ensure the bulb is correctly installed as per Section 4.

This bulb is non-dimmable. Do not use with dimmer switches.
6. Maintenance
The E-Simpo G23 LED bulb requires minimal maintenance:
- Cleaning: Ensure the power is off before cleaning. Gently wipe the bulb with a soft, dry cloth. Do not use liquid cleaners or abrasive materials.

- Disposal: Dispose of old LED bulbs according to local regulations for electronic waste.
7. Troubleshooting
If you encounter issues with your E-Simpo G23 LED bulb, refer to the following troubleshooting guide:
| Problem | Possible Cause | Solution |
|---|---|---|
| Bulb does not light up | No power to the fixture Bulb not seated correctly Electronic ballast not bypassed | Check circuit breaker and wall switch Re-insert bulb firmly into the socket Bypass the electronic ballast as per Section 4 |
| Bulb flickers or hums | Incompatible electronic ballast still in circuit Loose connection | Bypass the electronic ballast as per Section 4 Check all wiring connections for tightness |
| Bulb emits smoke or burning smell | Electronic ballast not bypassed (severe) Incorrect voltage | Immediately turn off power at the circuit breaker. Do not use the bulb. Consult a qualified electrician. Ensure fixture voltage matches bulb specifications. |
