E27 Golf Ball 4.5W Filament LED Bulb - Warm White

This E27 LED bulb takes the small round golf ball (G45) shape, measuring just 45 mm across and 78 mm tall. It draws 4.5 W and gives out 470 lumens of 2700K warm white light, a soft, mellow tone that suits living spaces. The cap is an E27 Edison Screw, known as ES in the UK and the same screw fitting US buyers call a medium base. Inside the clear glass sit visible LED filaments, giving the bulb the vintage look of an old incandescent while running on modern LED efficiency at 104 lm/W. The beam spreads across 320 degrees, so light radiates almost all the way around the bulb rather than throwing in one direction.

At 4.5 W this bulb replaces a 40 W old incandescent golf ball, so it slots straight into existing E27 fittings without losing brightness. The warm 2700K tone and 80 CRI colour rendering make it a good fit for pendants, wall lights, table lamps and small fittings in bedrooms, living rooms and hallways. Because the filaments are on show through clear glass, it works best in open or exposed fittings where the lamp itself is part of the look, rather than hidden behind a heavy shade. It is rated IP20 for dry indoor use only, so keep it clear of bathrooms, porches and any outdoor or damp location.

The bulb runs on 220 to 240 V AC mains and weighs only 16 g, with a clear transparent glass envelope over the filament array. It is a non-dimmable lamp, so pair it with a standard on/off switch rather than a dimmer circuit. Rated for 15,000 hours, it should give years of service in everyday use before needing replacement. This is part of a wider range of E27 filament bulbs in matching shapes and outputs, so a whole room can be fitted with the same warm look.

Product Specification Sheet

Range Datasheet

Which fitting does this bulb need?

It has an E27 cap, also called Edison Screw or ES, which is the larger screw-in fitting. It twists straight into any standard E27 lampholder, so it suits most pendants, table lamps and wall lights that take a screw bulb.

What old bulb wattage does it replace?

It draws just 4.5 W but gives 470 lumens, which matches the output of an old 40 W incandescent golf ball. The LED itself only uses 4.5 W, so you get the same brightness for a fraction of the running cost.

Is this bulb dimmable?

No, this is a non-dimmable bulb. Use it on a standard on/off switch rather than a dimmer, as fitting it to a dimmer circuit can cause flicker or shorten its life.

What does the warm white colour look like?

At 2700K it gives a soft, warm white close to the glow of a traditional bulb, ideal for relaxed living spaces. With visible LED filaments behind clear glass it also has a vintage look, and its 80 CRI rendering shows colours naturally.
