Product information

Description

The Osram STAR LED bulb with a GU4 base is a highly efficient lighting solution designed to replace traditional 35W halogen lamps while consuming only 4W of power. This compact LED provides a luminous flux of 345 lumens, delivering a warm white light at a color temperature of 2700K. With a focused 36-degree beam angle, it is engineered to provide precise illumination for various indoor settings, ensuring both energy savings and consistent light quality over a long operational lifespan.

Advantages

This LED bulb offers significant energy efficiency, reducing electricity consumption compared to conventional halogen alternatives. Its robust design ensures a long service life of up to 15,000 hours, which minimizes the frequency of replacements and maintenance efforts. The GU4 base allows for straightforward installation in compatible fixtures, while the warm white light output creates a comfortable and inviting atmosphere in any space. Furthermore, the focused beam angle makes it an excellent choice for highlighting specific objects or architectural features without excessive light spill.

Suitable for

  • Accent lighting in display cabinets and shop windows
  • Illumination in museums and art galleries
  • General lighting in exhibition rooms
  • Residential interior lighting
  • Downlighting for walkways, doors, and stairs
  • Outdoor use when installed in suitable, weather-protected luminaires

When it may not be suitable

This bulb is not suitable for use in dimmable circuits, as it is designed for standard on-off operation. Additionally, it may not be appropriate for general ambient room lighting due to its narrow 36-degree beam angle, which is specifically intended for directional spot lighting rather than wide-area illumination.

Key specifications

  • Power consumption: 4W
  • Equivalent power: 35W
  • Base type: GU4
  • Luminous flux: 345 lm
  • Color temperature: 2700K (Warm White)
  • Beam angle: 36°
  • Lifespan: 15,000 hours
  • Color Rendering Index (CRI): 80
  • Power factor: 0.5

How to use

To install the bulb, ensure the power supply to the fixture is switched off. Carefully align the two pins of the GU4 base with the socket and push the bulb in gently, then twist slightly if the socket design requires it to lock into place. Once securely seated, restore power to the fixture. Avoid touching the bulb surface with bare hands if possible, and ensure the fixture is compatible with the 12V requirements of this GU4 lamp type.

What to consider before purchase

  • Verify that your existing fixture is compatible with a GU4 base.
  • Ensure the fixture is not connected to a dimmer switch.
  • Check that the 36-degree beam angle meets your specific lighting requirements.
  • Confirm that the fixture provides the correct voltage for this lamp.

Usage recommendations

For optimal performance and longevity, ensure the bulb is used in a well-ventilated fixture to prevent heat buildup. When using this product in outdoor environments, always house it within a luminaire that provides adequate protection against moisture and environmental elements.
