Description
This E27 LED bulb takes the classic A60 GLS shape, the rounded household form most fittings expect. It screws into a standard E27 Edison Screw (ES) holder, which US buyers will know as the medium screw base. Drawing just 3.4W, it puts out 470 lumens at 6500K, a crisp daylight tone, and stands in for an old 40W bulb while using a fraction of the power. The 180 degree beam spreads light broadly rather than directing it, so it fills a space evenly.
The bright 6500K daylight output and Ra90 colour rendering make this bulb well suited to kitchens, home offices, utility rooms and workshops where clear, accurate light helps with close work. The wide 180 degree spread means a single bulb lights a fitting without harsh shadows, and it works equally well in pendants, table lamps and open shades. As an IP20 bulb it is for dry indoor use only, so keep it clear of bathrooms, porches and any outdoor or damp location. Its 470 lumen output gives general task and ambient light rather than a focused spot.
The bulb measures Ø60 by 107 mm and weighs 28 g, sitting comfortably in standard A60 fittings. At 138 lm/W it is efficient, with a rated lifespan of 25,000 hours that cuts how often you climb a ladder to change it. It is non-dimmable, so pair it with a standard on/off circuit rather than a dimmer switch. The finish is a plain white diffused body that softens the light. This bulb sits within our wider E27 GLS range, with other wattages and colour tones available alongside it.

Frequently Asked
Which fitting does this bulb need?
It has an E27 Edison Screw (ES) cap, the standard large screw base. US buyers will know this as the medium screw base. It fits any A60 GLS holder of that size.
What old bulb wattage does it replace?
It replaces a 40W old-style bulb while drawing only 3.4W itself. The 470 lumen output and 138 lm/W efficiency deliver the same usable brightness for far less energy.
Is this a warm or cool bulb?
It runs at 6500K, a crisp daylight tone that reads bright and clean rather than warm. With Ra90 colour rendering it shows colours accurately, which suits kitchens, offices and task areas.
Is this bulb dimmable?
No, this is a non-dimmable bulb. Use it on a standard on/off circuit; fitting it to a dimmer switch can cause flicker or buzzing and may shorten its rated 25,000 hour life.
