E27 Golf Ball 4.5W Filament Opal LED Bulb - Warm White

This E27 golf ball LED bulb pairs a compact G45 shape with a visible filament arrangement behind clear glass, for the vintage look of an old incandescent lamp without the running cost. It draws just 4.5 W yet gives 470 lumens of 2700K warm white light across a wide 320 degree beam, so the glow spreads evenly rather than pointing in one direction. The cap is a standard E27 Edison Screw, known in the US as the medium screw base, and the small round form is what American buyers call a golf-ball or G45 bulb.

Being a warm, low-output lamp on a wide spread, it suits decorative and ambient duties rather than task work: pendants and cluster fittings over a dining table, multi-arm chandeliers, bedside and table lamps, wall brackets and hallway fittings where the filament is on show. The 2700K tone reads soft and homely, flattering to warm interiors and skin tones, while the Ra 80 colour rendering keeps everyday colours looking natural. It is rated IP20 for dry indoor use only, so keep it indoors and clear of bathrooms, porches and any damp or exposed position.

The bulb measures just Ø45 by 78 mm and weighs 18 g, so it slips neatly into small shades and exposed-lamp fittings. At 4.5 W it stands in for a 40 W old-style bulb, cutting the energy used while matching the brightness, and it runs on 220 to 240 V mains with no transformer needed. The light source is a G45 filament with a clear-glass envelope and a white finish, rated for 15,000 hours of use. Please note this bulb is non-dimmable, so pair it with a standard on/off switch rather than a dimmer circuit.

Product Specification Sheet

Range Datasheet

What fitting does this bulb need?

It has an E27 Edison Screw cap, the larger of the two common screw fittings, known as ES in the UK and the medium screw base in the US. It simply screws into any matching E27 holder, so there is no transformer or driver to add.

What old-style bulb wattage does it replace?

The LED itself draws only 4.5 W but gives 470 lumens, which is equivalent to a 40 W traditional incandescent bulb. You get the same familiar brightness for a fraction of the energy used.

Is this bulb dimmable?

No, this is a non-dimmable bulb. It should be used with a standard on/off switch and will not work correctly on a dimmer circuit, so check your switching before fitting.

What does the warm white colour look like?

At 2700K it gives a soft, warm glow close to a traditional filament lamp, ideal for relaxed living areas, bedrooms and decorative fittings. The Ra 80 colour rendering keeps furnishings and decor looking natural under the light.
