E27 Golf Ball 4.5W Filament LED Bulb - Cool White

This E27 golf ball LED bulb takes the small round G45 shape, with visible LED filaments behind clear glass for a vintage look. It fits the E27 Edison Screw cap, known as ES in the UK, while shoppers in the US will recognise the medium screw base on this style of LED bulb. The bulb draws just 4.5W and gives 470 lumens at 4000K cool white, a crisp neutral tone with Ra 80 colour rendering. With a wide 320 degree beam angle, light spreads evenly around the bulb rather than throwing in one direction, so the exposed filaments stay on show from most angles.

At 4.5W it replaces a 40W old incandescent bulb, so the brightness suits everyday fittings where the bulb is part of the look. The small G45 form and clear glass make it a good match for pendant clusters, exposed-flex fittings, wall brackets and decorative shades where a larger GLS bulb would look bulky. The cool white 4000K tone reads cleaner than warm white, which works well in kitchens, home offices and hallways where a brighter, more neutral light is wanted. This is a dry indoor bulb only, rated IP20, so keep it clear of bathrooms, porches and any outdoor or damp position.

The bulb measures 45 mm across and 78 mm long, weighs 18 g and runs on 220 to 240V AC mains through its E27 cap, so no separate driver or transformer is needed. The filament LED design carries a clear transparent glass envelope that suits open fittings, with a rated life of 15,000 hours and an efficiency of 104 lm/W. It is non-dimmable, so pair it with a standard on or off switch rather than a dimmer circuit. We stock this golf ball in the wider E27 filament range alongside other caps and shapes if you need to match it across a fitting.

Product Specification Sheet

Range Datasheet

Which fitting does this bulb need?

It has an E27 cap, the larger Edison Screw fitting also called ES in the UK. It screws into any standard E27 lampholder. Check your fitting takes E27 rather than the smaller E14 SES before ordering.

What old bulb wattage does it replace?

The LED itself draws only 4.5W but gives 470 lumens, which is equivalent to a 40W old incandescent golf ball bulb. You get the same useful brightness for a fraction of the energy. Over a 15,000 hour rated life that adds up to a clear saving.

Is this bulb dimmable?

No, this is a non-dimmable bulb, so it should be used on a standard on or off switch. Fitting it to a dimmer circuit can cause flicker or buzzing and may shorten its life. If you need dimming, choose a bulb listed as dimmable instead.

Can I use it outdoors or in a bathroom?

No. This bulb is rated IP20 for dry indoor use only, so keep it clear of bathrooms, porches and any outdoor or damp location. Use it in enclosed indoor fittings such as pendants, wall brackets and shades.
