E27 Golf Ball 3.8W Filament LED Bulb - Cool White

This golf ball LED bulb fits a standard E27 Edison Screw (ES) holder and gives the small, rounded G45 shape that suits compact fittings and decorative lamps. It draws just 3.8W while producing 806 lumens, replacing a 60W old bulb at a fraction of the running cost. The light is a crisp 4000K cool white spread across a wide 320 degree beam angle, so the output reaches well beyond a single direction. US buyers will recognise the G45 form as the household golf ball or small round bulb, here on the screw-fit cap.

Because of its compact size and even spread, this bulb works well in pendants, wall brackets, table lamps and multi-bulb fittings where a full-size GLS bulb would look bulky. The 320 degree beam keeps the light soft and surrounding rather than tightly directional, making it a good fit for general background light in living rooms, hallways and bedrooms. With a rated 4000K cool white tone it leans towards a clean, neutral light rather than a warm yellow, which suits kitchens and work corners. It is an indoor bulb only and should be kept out of bathrooms, porches and any damp or outdoor location.

The bulb uses visible LED filaments behind clear transparent glass, giving the vintage filament look while running at modern LED efficiency of 212 lm/W. It is rated for 50,000 hours and runs on 220 to 240V AC mains through the E27 cap, with a colour rendering of Ra 80 for natural-looking tones. This is a non-dimmable bulb, so it is best paired with a standard on/off switch rather than a dimmer circuit. The same filament range is offered in other shapes and caps if you need a matching look across different fittings.

Product Specification Sheet

Range Datasheet

Which fitting does this bulb need?

It has an E27 cap, also known as Edison Screw or ES, which is the larger screw-in fitting found on many pendants, lamps and ceiling fittings. Simply screw it into any E27 holder. If your fitting uses the smaller E14 screw or a bayonet cap, this bulb will not fit.

What old bulb wattage does it replace?

The bulb draws only 3.8W itself but gives 806 lumens, which is equivalent to a 60W traditional incandescent bulb. You get the same brightness for a fraction of the energy use, with a rated life of 50,000 hours.

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 flicker or buzzing and may shorten its life.

What does the filament design look like when lit?

It uses visible LED filaments inside clear transparent glass, giving the vintage filament appearance that suits exposed fittings and decorative lamps. The light is a 4000K cool white with Ra 80 colour rendering, so tones look clean and natural.
