E27 GLS LED Bulb 7.8W 75W-eq 1055lm 180° A60 - Cool White

This E27 GLS LED bulb is a classic A60 household bulb with the familiar rounded shape, fitting any standard E27 Edison Screw (ES) holder. It draws just 7.8 watts while producing 1055 lumens, which is the kind of brightness you would previously have got from a 75 watt old-style bulb, so the saving in running power is substantial against the same light output. The tone is 4000K cool white, a clean, neutral light that keeps colours looking true, and the wide 180 degree beam spreads light broadly rather than narrowly. A high CRI of Ra 90 means whites stay white and colours read accurately under it.

Because it throws light across a wide 180 degree spread, this bulb suits open fittings, pendants, table and floor lamps where light needs to fill a space rather than point in one direction. The cool white tone works well in kitchens, home offices, utility areas and workshops where a crisp, alert light helps with tasks and detail. Light output is broad and even rather than directional, so it is a good general-purpose replacement bulb wherever an old 75 watt incandescent once sat. As an IP20 bulb it is for dry indoor use only, so keep it clear of bathrooms, porches and any outdoor or damp position.

The bulb measures Ø60 by 109 mm and weighs only 34 grams, matching the dimensions of a standard A60 lamp so it sits neatly in most shades and fittings. It runs on 220 to 240V AC mains through its E27 cap, with an efficiency of 135 lm/W and a rated lifespan of 25,000 hours. This is a non-dimmable bulb, so pair it with a standard on/off switch rather than a dimmer circuit. The finish is white with an opal-style diffused look that softens glare. We stock matching E27 bulbs in other wattages and tones across the range if you need to fill several fittings at once.

Product Specification Sheet

Range Datasheet

Which fitting does this bulb need?

It has an E27 Edison Screw (ES) cap, the larger of the two common screw fittings. It screws into any standard E27 holder, including pendants, table lamps and ceiling fittings that take a full-size screw bulb.

What old bulb wattage does it replace?

The LED itself draws only 7.8 watts but gives 1055 lumens, which matches the brightness of a 75 watt old-style incandescent bulb. You get the same light for a fraction of the power, which is where the energy saving comes from.

Is this bulb dimmable?

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

What does cool white look like and where does it suit?

At 4000K it gives a clean, neutral cool white light, brighter and crisper than warm white but not as blue as full daylight. With its Ra 90 colour rendering it suits kitchens, home offices and utility spaces where you want clear, accurate light for tasks.
