Usage and Installation Guide
Installation Steps:
Power Off: Ensure the main power supply to the existing light fixture is switched off at the circuit breaker.
Remove Old Tube: Carefully remove the traditional fluorescent tube by twisting it gently and pulling it out of the sockets.
Bypass Ballast: This is a critical step. For most LED tube installations, you must remove or bypass the old electromagnetic ballast and starter. Connect the AC power directly to the lamp holders at both ends of the fixture. (Note: Some regional standards, like the US, may require wiring to the same end) .
Install LED Tube: Insert the new T4 LED tube into the sockets, ensuring the pins are aligned correctly. Gently push and twist to secure it in place.
Power On: Restore the power and test the light.
Precautions:
Waterproofing: While the IP33 rating offers basic protection against moisture, it is not suitable for direct exposure to water. In humid environments, additional protective measures are recommended .
Heat Dissipation: Ensure the fixture allows for adequate ventilation to prevent overheating, which can affect the LED's lifespan.
Voltage Compatibility: Although the light supports a wide voltage range (85-265V), prolonged operation at the extremes can affect efficiency and lifespan .
