5. Installation Instructions (Ballast Bypass, Dual-End Powered)
These JESLED 8FT LED tubes require a ballast bypass installation. This means the existing ballast in your fluorescent fixture must be removed or bypassed, and the fixture rewired to directly supply line voltage to the lamp holders (tombstones).
Tools Required:
- Wire cutters/strippers
- Screwdriver
- Wire nuts
- Electrical tape
- Voltage tester
Installation Steps:
- Turn Off Power: Locate the circuit breaker controlling the fixture and turn off the power. Verify with a voltage tester that the power is off before proceeding.
- Remove Existing Fluorescent Tubes: Carefully remove the old fluorescent tubes from the fixture.
- Access the Ballast: Open the fixture to expose the wiring and the ballast.
- Bypass/Remove Ballast:
Cut off all wires connected to the ballast. You will typically have a live (black) and neutral (white) wire going into the ballast, and multiple wires (often yellow, red, blue) going from the ballast to the lamp holders (tombstones).
Figure 5.1: Ballast bypass wiring diagram. Connect the live wire to one end of the LED tube and the neutral wire to the other end.
Connect the live (hot) wire from the main power supply to the wires leading to one end of the fixture's lamp holders. Connect the neutral wire from the main power supply to the wires leading to the other end of the fixture's lamp holders. Use wire nuts to secure all connections and electrical tape for added insulation.
- Install LED Tubes: Insert the JESLED 8FT LED tubes into the modified fixture. Ensure the single pins are securely seated in the lamp holders.
- Apply Warning Label: Affix the provided warning label to the fixture to indicate that it has been modified for LED lamps and no longer uses a ballast. This prevents accidental installation of fluorescent lamps in the future.
- Restore Power: Close the fixture and turn the power back on at the circuit breaker.

6. Operating Instructions
JESLED 8FT LED Bulbs are designed for simple operation once correctly installed:
- Instant On: These LED tubes provide instant illumination with no flickering or warm-up time.
- Non-Dimmable: These specific models are non-dimmable. Do not attempt to use them with standard dimmer switches, as this may damage the bulbs or the dimmer.
- Optimal Performance: For best performance, ensure the bulbs are used within their specified voltage range (120-277 Volts).

7. Maintenance
JESLED LED bulbs require minimal maintenance due to their long lifespan and durable construction.
- Cleaning: Ensure power is off before cleaning. Gently wipe the tubes with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
- Inspection: Periodically inspect the tubes and wiring for any signs of damage or loose connections. Address any issues promptly.
- Lifespan: With an average lifespan of 50,000 hours, these bulbs are designed to last over 5 years with typical use, significantly reducing the frequency of replacements.
8. Troubleshooting
If you encounter issues with your JESLED LED bulbs, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| LED tube does not light up | No power to the fixture; incorrect wiring; loose connection; faulty tube. | Check circuit breaker. Verify wiring connections (live to one end, neutral to other). Ensure tubes are securely seated. Test with a known working tube. |
| Flickering or inconsistent light | Loose connection; incompatible dimmer (if used); EMI. | Check all wiring connections. Ensure no dimmer is used, as these bulbs are non-dimmable. Relocate away from sources of strong electromagnetic interference. |
| Radio or garage door opener interference | Electromagnetic Interference (EMI) from the LED driver. | Install the LED tubes away from sensitive electronic devices. Ensure proper grounding of the fixture. |
| Tube sags in the middle | Lack of central support for 8FT tubes. | Install additional support clips in the middle of the 8FT tube to prevent sagging. |
