Installation Instructions
Important: Installation of these LED bulbs requires modification to the existing fixture. It is recommended that installation be performed by a qualified electrician.
- Disconnect Power: Before beginning any work, ensure the power supply to the fixture is completely turned off at the circuit breaker or fuse box. Verify with a voltage tester.
- Remove Existing Fluorescent Bulbs: Carefully remove the old fluorescent T5 bulbs from the fixture.
- Bypass/Remove Ballast: The existing fluorescent ballast must be removed or bypassed. These LED bulbs operate directly on 120V line voltage and do not require a ballast. This may involve disassembling the fixture.
- Check Lampholders: These LED bulbs require shunted lampholders. Only one pin on each end of the LED lamp is connected to the internal circuitry. If your existing lampholders are not shunted, you may need to rewire the fixture to ensure proper connection to the correct pins. Consult the fixture's wiring diagram or a qualified electrician.
- Physical Fit: Note that the diameter of this LED bulb may be slightly larger than a standard T5 fluorescent bulb, approaching the size of a T8. Ensure there is sufficient clearance within your fixture for the bulb to fit without obstruction.
- Install LED Bulbs: Once the fixture is correctly wired for direct 120V input and has shunted lampholders, carefully insert the Satco S11902 LED bulbs into the lampholders.
- Restore Power: Once all bulbs are securely installed and wiring is complete, restore power to the fixture at the circuit breaker.
- Test Operation: Turn on the light switch to verify proper operation.
Note: The last 1.5 inches of the bulb, typically under the label, house the AC-DC converter and do not emit light. This means the effective illuminated length is approximately 7.5 inches. This is a design characteristic and not a defect.
Operating Instructions
Once installed, the Satco S11902 LED bulbs operate like any standard light bulb. Simply use the wall switch or fixture control to turn the light on or off. The product specifications mention "App" and "Push Button" control methods with "Infrared" connectivity; however, for a standard bulb, these typically refer to the capabilities of the fixture or a smart home system it integrates with, not the bulb itself. The bulb itself is controlled by applying or removing 120V power.
Maintenance
- Cleaning: Ensure power is off before cleaning. Wipe the bulb with a soft, dry cloth. Do not use liquid cleaners or abrasive materials.
- Replacement: These LED bulbs have a long lifespan. When replacement is necessary, follow the installation instructions in reverse order to safely remove the old bulb and install a new one.
- Disposal: Dispose of old LED bulbs according to local regulations for electronic waste.
Troubleshooting
