Clear Glass Filament Design
The transparent glass construction displays the decorative LED filaments, reproducing the appearance of a traditional incandescent lamp. Unlike opaque LED bulbs, the visible filament design makes this golf ball lamp particularly attractive in exposed fittings, wall lights and decorative pendants.
The Knightsbridge GBD4AESC 4W LED Golf Ball Bulb measures just 45mm in diameter and 76mm in height, making it suitable for compact luminaires where a standard GLS bulb may be too large.
2700K Very Warm White Lighting
Producing 490 lumens at 2700K, this LED filament lamp provides a comfortable, welcoming light for living rooms, bedrooms, dining areas and hospitality interiors.
The wide 330° beam angle allows light to spread around the fitting, making it especially useful in decorative fixtures where broad illumination is required.
Dimmable LED Performance
The Knightsbridge GBD4AESC 4W LED Golf Ball Bulb supports adjustable brightness when connected to a suitable LED dimmer. This allows lighting levels to be changed for everyday use or reduced to create a softer evening atmosphere.
The manufacturer advises compatibility with most trailing-edge LED dimmers. Always check the dimmer’s operating range and minimum load requirements before installation.
Energy-Efficient 40W Lamp Replacement
Consuming only 4W, this LED golf ball lamp uses approximately 90% less electricity than a traditional 40W incandescent bulb while providing comparable light output.
Its 15,000-hour rated lifespan helps reduce replacement frequency, offering a practical solution for frequently used fittings and installations containing multiple lamps.

- Decorative wall lights and ceiling fittings
- Table lamps and bedside lights

The E27 Edison Screw cap allows straightforward installation into compatible ES lamp holders. Check the available space within the fitting against the lamp’s dimensions of 45mm diameter and 76mm height.
