Full details

Its key benefit is providing a comfortable 2700 K warm white light while consuming only 4.8 W, offering significant energy savings over traditional incandescent bulbs. A minor caveat is its 'F' energy efficiency class rating, which is standard for many LED bulbs but might be a consideration for those prioritizing the highest efficiency categories. This dimmable bulb features a clear finish and a standard E27 socket, making it a versatile replacement for many existing fixtures. It delivers 470 lumens of light and has an average lifespan of 1500 hours.

FAQs
What is the colour temperature of this bulb?
The bulb has a warm white colour temperature of 2700 K, which provides a cozy and inviting light.
Can I use this bulb in any light fixture?
This bulb is designed for fixtures using an E27 screw base and a 240 V power supply. Always ensure the fixture is suitable for the bulb's dimensions and type.
Is this bulb suitable for outdoor use?
The product information does not specify suitability for outdoor use. It is generally recommended for indoor applications unless the fixture provides adequate protection against the elements.
How do I know if my dimmer switch is compatible?
Check your dimmer switch's specifications for compatibility with LED bulbs and the specific wattage range. Look for dimmers explicitly marked as 'LED compatible'.
What does the 'F' energy efficiency class mean?
The 'F' rating indicates the bulb's position on the European energy efficiency scale (A++ to E). While not the highest rating, it still signifies energy savings compared to older, less efficient lighting technologies.
How long will this bulb typically last?
The bulb has an average rated lifespan of 1500 hours.
Can I replace a 60W incandescent bulb with this 4.8W LED bulb?
Yes, this 4.8W LED bulb provides approximately 470 lumens, which is equivalent in brightness to a 40W incandescent bulb. For replacing a 60W incandescent, you might need a higher lumen LED option, but for general warm ambiance, this bulb is often suitable.
Troubleshooting
Bulb does not turn on
Ensure the bulb is screwed in tightly into the E27 socket. Check that the power supply is on and the circuit breaker is not tripped. Verify the light fixture is functioning correctly with another compatible bulb. If the bulb is dimmable, ensure it is used with a compatible dimmer switch and not a standard on/off switch if the dimmer requires load.
Bulb flickers when dimmed
This may indicate incompatibility with the dimmer switch. Ensure the dimmer switch is rated for LED bulbs and is compatible with the specific wattage and type of this Osram bulb. Try testing the bulb with a different compatible LED dimmer switch.
Light output is lower than expected
Check the lumen output rating (470 lumens) to ensure it meets your lighting needs. Verify that the bulb is clean and free from dust or debris. Ensure the fixture itself is not obscuring the light output.

Setup, Compatibility & Care
Setup: This bulb features a standard E27 screw base. Ensure the power to the light fixture is switched off before removing the old bulb and screwing in the new Osram LED bulb. Once installed, switch the power back on.
Compatibility: The bulb requires a 240 V power supply and is compatible with fixtures designed for E27 screw-in bulbs. It is dimmable, but you must use a compatible dimmer switch. Using a non-dimmable switch will not affect the bulb's function, but you will not be able to adjust its brightness. Using an incompatible dimmer switch may cause flickering or premature failure.
Care: To maintain optimal performance, periodically clean the bulb and fixture. Ensure the power is off before cleaning. Use a dry or slightly damp soft cloth. Avoid using abrasive cleaners or solvents, as these can damage the bulb's finish or internal components.
