FAQs

What is the lifespan of these bulbs?

These Osram LED Star Flat bulbs have a lifespan of up to 25,000 hours.

Can I use these bulbs outdoors?

Yes, but only when installed in a suitable outdoor lighting fixture with a minimum IP rating of IP65 to protect against moisture and dust.

What is the color temperature of these bulbs?

The specific color temperature is not provided in the product description, but the CRI of 80 indicates pleasant interior lighting.

Are these bulbs dimmable?

The product description does not specify if these bulbs are dimmable. It is recommended to check the packaging or product specifications for dimming capabilities.

What does CRI 80 mean?

CRI stands for Colour Rendering Index. A CRI of 80 means the lamp provides good color rendering, accurately reflecting the colors of objects under its light.

What is the energy efficiency class?

These bulbs have an energy efficiency class of G, according to the EU energy labeling system.

How do I clean these bulbs?

Turn off the power and let the bulb cool down. Clean gently with a dry or slightly damp cloth. Avoid using cleaning agents.

Troubleshooting

Bulb does not light up

Check that the bulb is correctly screwed into the E27 socket. Ensure the power supply is on and the circuit breaker is not tripped. Try the bulb in a different working lamp to test functionality.

Flickering light

Ensure the bulb is securely seated in the socket. If flickering persists, the socket or wiring may be faulty, or the bulb may be nearing the end of its lifespan. Consider replacing the bulb.

Poor performance in outdoor fixture

Verify that the outdoor fixture has an IP rating of at least IP65. Ensure the fixture is properly sealed and free from water or debris ingress. The bulb itself is not waterproof.
