Description

The Osram ST CLAS A 19 W E27 Warm white 2700 K LED bulb by Ledvance delivers 19 W power and warm white light at 2700 K with a luminous flux of 2452 lm. Designed for standard E27 fittings, the lamp offers a beam angle of 150° and a Color Rendering Index (CRI) of 80, with a rated lifetime of approximately 15,000 hours. It is suitable for domestic and general illumination and may be used outdoors only in appropriate luminaires.

Advantages

This LED bulb provides efficient lighting with a high luminous flux for its wattage, a warm colour temperature that suits living spaces, and a long service life of up to 15,000 hours. The standard E27 cap ensures compatibility with common fixtures, while the 150° beam angle offers wide light distribution. The CRI of 80 delivers acceptable colour rendering for everyday applications.

Suitable for

  • Domestic rooms (living rooms, bedrooms, kitchens)
  • General indoor illumination in homes and small commercial spaces
  • Outdoor use when installed in appropriate weather-protected luminaires

How to use

Ensure the light fixture accepts an E27 lamp and is switched off before installation. Screw the bulb into the socket until secure, then switch the power on. Use the bulb in dry indoor locations or place it in a suitable outdoor luminaire that provides protection from weather and moisture if used outdoors.

Usage recommendations

For optimal performance, replace bulbs with the same fitting and similar luminous flux; avoid installing dimmable bulbs on non-dimmable circuits. When used outdoors, select luminaires rated for exterior use to protect the lamp from direct exposure to water and extreme conditions.
