Product information

Description

The Osram STAR LED bulb is a high-quality, energy-efficient lighting solution designed to replace traditional halogen lamps. With a power consumption of only 4.3W, this bulb delivers a luminous flux of 350 lm, providing reliable and consistent illumination. It features a standard E27 base, making it compatible with a wide range of existing fixtures, while its warm white color temperature of 2700K creates a comfortable and inviting atmosphere in any space.

Advantages

This LED bulb offers significant energy savings compared to conventional lighting, helping to reduce electricity costs without compromising on light quality. Its compact design allows for easy installation in various luminaires, serving as a direct replacement for halogen reflectors. The bulb provides instant 100% light output upon switching on, eliminating any warm-up time. With a long operational lifespan of up to 15,000 hours, it minimizes the need for frequent replacements, ensuring long-term performance and reliability for both residential and commercial applications.

Suitable for

  • Display cabinets and shop windows
  • Museums and art galleries
  • Hospitality environments
  • Residential interiors
  • Downlighting for walkways, doors, and stairs

This bulb may not be suitable for applications requiring high-intensity general room lighting due to its focused 36-degree beam angle. It is also not intended for use in exposed outdoor environments unless installed within a fully protected, suitable luminaire.

Key specifications

  • Base type: E27
  • Power consumption: 4.3W
  • Luminous flux: 350 lm
  • Color temperature: 2700K (Warm White)
  • Beam angle: 36 degrees
  • Lifespan: 15,000 hours
  • Color Rendering Index (CRI): 80
  • Voltage: 220-240V

To use the Osram STAR LED bulb, simply ensure that your existing light fixture is compatible with an E27 base. Turn off the power supply to the fixture before removing the old bulb. Carefully screw the LED bulb into the socket until it is secure. Once installed, restore the power and switch on the light to enjoy immediate, flicker-free illumination.

What to consider before purchase

  • Check that your fixture supports the E27 base type.
  • Verify if the 36-degree beam angle meets your specific lighting needs.
  • Ensure the bulb is used in a suitable environment, especially for outdoor applications.
For optimal performance and longevity, ensure the bulb is used in well-ventilated fixtures and avoid exposure to moisture unless the luminaire is specifically rated for outdoor use.

Technical details

International Protection (IP) code: The IP code classifies and rates the degree of protection provided against the intrusion (including body parts such as hands and fingers), dust, accidental contact, and water by mechanical casings and electrical enclosures. It is published by the International Electrotechnical Commission (IEC). The digits (characteristic numerals) indicate conformity with the conditions summarized in the tables below. Where there is no protection rating with regard to one of the criteria, the digit is replaced with the letter X. an electrical socket rated IP22 is protected against insertion of fingers and will not be damaged or become unsafe during a specified test in which it is exposed to vertically or nearly vertically dripping water. Another example is the Sony Xperia Z Ultra, one of the first cellular phones to be IP-rated; it is rated at IP58 and marketed as "dust resistant" and can be "immersed in 1.5 meter of freshwater for up to 30 minutes".
