E14 Golf Ball 4.5W Filament LED Bulb - Opal Warm White

This E14 golf ball LED bulb pairs a compact G45 shape with visible LED filaments behind clear glass, giving the vintage look of an old wire-filament lamp from a modern light source. It draws just 4.5 W yet stands in for a 40 W incandescent, returning 470 lumens of 2700K warm white through a wide 320 degree beam. The cap is E14 Small Edison Screw, known across the US as the candelabra fitting, so it threads straight into smaller pendants, wall lights and chandeliers that take the slimmer screw base.

The warm 2700K tone and Ra 80 colour rendering suit the rooms where a soft, relaxed light matters more than raw brightness, such as living rooms, bedrooms, dining areas and hallway fittings. Because the filaments are on show, this bulb works best in clear-shaded or open fittings where the glass is part of the look rather than hidden behind a dense diffuser. The 320 degree spread throws light almost all the way around the bulb rather than in a single direction, so a cluster of them in a multi-arm fitting fills a space evenly with a gentle glow.

The bulb measures 45 mm across and 80 mm long, weighs 16 g and runs on 220 to 240 V AC mains with no transformer needed. It is rated IP20 for dry indoor use only and carries a 15,000 hour lifespan at an efficiency of 104 lm/W. This version is non-dimmable, so it should be paired with a standard on/off switch rather than a dimmer. The opal-white finish detailing keeps the lamp tidy when off. It sits within our wider E14 filament range alongside candle and globe shapes.

Product Specification Sheet

Range Datasheet

Which fitting does this bulb need?

It uses an E14 Small Edison Screw (SES) cap, the slimmer screw fitting found on smaller pendants, wall lights and chandeliers. In the US this is the candelabra base. Check that your fitting takes E14 rather than the larger E27 before ordering.

What old bulb wattage does it replace?

The LED draws only 4.5 W but produces 470 lumens, which matches the light output of an old 40 W incandescent golf ball bulb. You get the same brightness for a fraction of the energy use, and the bulb itself never draws anything like 40 W.

Is this bulb dimmable?

No, this is a non-dimmable bulb and should be used with a standard on/off switch. Fitting it to a dimmer circuit can cause flickering or buzzing and may shorten its life, so pair it with regular switching.

What does warm white at 2700K look like?

2700K is a soft, warm tone close to traditional incandescent light, ideal for relaxed living and sleeping spaces rather than task areas. Combined with the visible filaments and clear glass, it gives a cosy vintage glow with Ra 80 colour rendering.
