Installation Guide & Important Notes
Warning: Unlike traditional fluorescent tubes, this LED tube light requires a direct connection to the mains supply. Failure to modify the existing fixture correctly may damage the product.
Retrofit Steps (Replacing Old Fluorescent Tubes):
- Power Off: Ensure the main power supply to the light fixture is completely switched off.
- Remove Old Tube: Carefully remove the existing T8 or T12 fluorescent tube.
- Bypass Ballast: This is a critical step. The magnetic or electronic ballast and starter (if present) must be completely removed or bypassed from the circuit.
- Direct Wiring: Connect the mains power (AC 165-260V) directly to the lamp holder pins on both ends of the fixture.
- Install LED Tube: Insert the new Qili T8 LED tube into the G13 lamp holders and rotate it 90 degrees to secure it.
- Power On: Restore the power and test the light.
Note: Some regions (like the US) may require wiring to a single end (single-ended power). Always check local electrical codes.
