4W Dimmable LED Golf Ball Filament Bulb E14 2700K - Clear Glass

The Knightsbridge 4W LED golf ball bulb uses exposed filament technology inside a clear glass envelope to replicate the appearance of a traditional 40W incandescent bulb while drawing just 4W from 230V mains. The E14 small Edison screw base fits chandelier-style fittings, wall lights and table lamps where the bulb is visible. The 2700K warm white output delivers 490lm through a 310-degree beam angle, providing ambient light rather than focused task light.

Designed for decorative fittings where the bulb itself is part of the aesthetic, the clear glass shell shows four LED filament strips arranged in a traditional tungsten-style layout. The 45mm diameter and 78mm overall height fit standard candelabra fittings, chandelier arms and compact table lamp shades without overhang. The bulb is dimmable when paired with compatible trailing edge dimmers, allowing output to be reduced for evening ambience or increased for functional light.

The filament construction gives this bulb a higher efficacy of 132.2lm/W compared to older LED designs, meaning it produces more light per watt consumed. The L70B50 rating of 15,000 hours indicates the bulb will retain at least 70% of its initial brightness after 15,000 hours of use under typical operating conditions. The warm 2700K colour temperature matches the glow of traditional incandescent bulbs, sitting at the warmer end of the white spectrum and pairing well with brass, copper and timber finishes.

Product Specification Sheet

Is this bulb dimmable?

Yes, the bulb is dimmable when paired with compatible trailing edge dimmers. Dimmer compatibility varies by manufacturer and model, so verify your dimmer supports LED filament bulbs before installation. Leading edge dimmers designed for older incandescent bulbs may cause flickering or reduced dimming range.

What fitting does it replace?

This 4W LED bulb replaces a traditional 40W incandescent golf ball bulb in any E14 (small Edison screw) fitting. The 490lm output provides comparable brightness to a 40W tungsten bulb while consuming 90% less energy.

Where is this bulb typically used?

The E14 golf ball format suits chandelier arms, decorative wall lights, bedside table lamps and any fitting where the bulb is visible and smaller than a standard A60 shape. The clear glass and exposed filament design works best in fittings where the bulb itself contributes to the aesthetic rather than being hidden inside a shade.

What does the 2700K colour temperature mean?

2700K sits at the warm end of the white light spectrum, producing a soft yellow-white glow similar to traditional incandescent bulbs. This colour temperature suits living rooms, bedrooms and dining areas where a warm, relaxed atmosphere is preferred over the cooler daylight tones of 4000K or 5000K bulbs.
