Product Information
Full details
This Osram LED bulb is designed for users seeking efficient and glare-free lighting in visible fixture applications. Its key benefit is the silver mirrored head, which directs light downwards and prevents direct glare, while providing a warm, inviting 2700K light. A caveat is that this bulb is not dimmable. It offers a 6.5W output, equivalent to a 50W incandescent, with a 650 lm luminous flux and an estimated lifespan of 15,000 hours.

FAQs
Is this bulb dimmable?
No, this Osram LED bulb is not dimmable. It is designed for use with standard on/off switches only. Using it with a dimmer may cause flickering or damage to the bulb.
What is the benefit of the mirrored head?
The silver mirrored head reflects light downwards, preventing it from scattering upwards and reducing direct glare. This makes it ideal for fixtures where the bulb is visible, creating a more comfortable and focused lighting effect.
How does this bulb compare to a 50W incandescent bulb?
This 6.5W LED bulb provides a similar light output (650 lumens) to a traditional 50W incandescent bulb, but uses significantly less energy and has a much longer lifespan.
What is the color temperature of this bulb?
The color temperature is 2700 Kelvin (K), which is considered warm white. This provides a cozy and inviting light, similar to that of traditional incandescent bulbs.
What is the lifespan of this LED bulb?
The estimated lifespan of this bulb is up to 15,000 hours, with a rating of 100,000 on/off cycles. This is considerably longer than standard incandescent bulbs.
Can I use this bulb in an enclosed light fixture?
While LED bulbs produce less heat than incandescent bulbs, it's generally recommended to use them in fixtures that allow for some air circulation. Check the specifications of your fixture for compatibility and optimal performance.
What does 'Energy efficiency class F' mean?
Energy efficiency classes range from A (most efficient) to G (least efficient). Class F indicates that while it is more efficient than older technologies like incandescent, there are more energy-efficient LED options available on the market.
Troubleshooting
Bulb does not light up.
Ensure the bulb is screwed in securely to the E27 socket. Check that the power supply to the fixture is active. Verify the bulb is not faulty by testing it in another compatible fixture. Ensure the fixture's switch is turned on.
Bulb flickers.
This can sometimes occur if the bulb is used with a dimmer switch, as this model is not dimmable. Ensure it is connected to a standard on/off switch. Check for loose connections in the fixture or wiring. Try the bulb in a different fixture to rule out fixture-related issues.
Poor light output.
Confirm the bulb is the correct wattage and type for your needs. Ensure the fixture is clean and not obstructing light. If the bulb is new, check that the protective film (if any) has been removed from the mirrored head.
