Troubleshooting

Bulb flickers when turned on

Pros and Cons

Pros

  • High lumen output for low energy consumption
  • Instant illumination without delay
  • Long 25,000-hour operational lifespan
  • Ideal color temperature for task lighting

Cons

  • Energy efficiency rated as Class E
  • Not intended for dimmable light circuits

Setup, Compatibility & Care

Installation is simple due to the standard G9 base; ensure the power is switched off before handling the bulb to prevent electrical shock. Push the two pins of the G9 base into the fixture socket until secure. Always check that the fixture rating matches the 4.2W power draw of the LED. To maximize lifespan, avoid touching the bulb with bare hands if possible, as natural skin oils can leave residues on the surface. If the bulb surface becomes dusty, clean it gently with a dry, lint-free cloth while the bulb is cold. Ensure the fixture is not on a dimmer switch, as this product is designed for standard on/off operation.
