Troubleshooting
Bulb does not turn on
Ensure the power supply is switched on. Check that the bulb is securely screwed into the B22d socket. Verify the light fixture is receiving power by testing with another known working bulb. Ensure the bulb is not being used with a dimmer switch.
Flickering or intermittent light
This is often caused by incompatibility with dimmer switches. Ensure the bulb is used in a standard, non-dimmable fixture. Check the bulb seating in the socket; a loose connection can cause flickering. If the issue persists, the bulb may be faulty.
Reduced brightness or premature failure
Ensure the bulb is operating within the specified voltage range (220-240V). Check for any physical damage to the bulb. If used in an enclosed outdoor luminaire, ensure adequate ventilation to prevent overheating, although LED bulbs produce less heat than incandescents.

Setup, Compatibility & Care
Setup: Ensure the light fixture is switched off before attempting to replace an existing bulb. Unscrew the old bulb and screw in the new OSRAM LED Filament lamp firmly into the B22d bayonet socket. Once installed, switch the power back on.
Compatibility: This bulb uses a B22d bayonet fitting and operates on a standard 220-240V AC power supply with a frequency of 50-60 Hz. It is compatible with most light fixtures designed for B22d bulbs. Crucially, this bulb is not dimmable and should not be used with dimmer switches, as this can cause malfunction or damage.
Care: To maintain optimal performance, clean the bulb periodically with a dry or slightly damp soft cloth. Avoid using abrasive cleaners or solvents. Ensure the bulb is cool before cleaning. For indoor use, cleaning is straightforward. If used outdoors in a suitable luminaire, ensure the luminaire itself is maintained according to its specifications.
