E27 GLS LED Bulb 3.4W 40W-eq 180° 470lm A60 - Warm White

This E27 GLS LED bulb takes the familiar A60 shape, the classic rounded household form that drops into almost any standard fitting. The cap is an E27 Edison Screw (ES), known in the US as a medium-base bulb, so it suits existing lamps and pendants without an adaptor. It draws 3.4W yet gives out 470 lumens at 2700K warm white, a soft, settled tone that suits living spaces. With a 180 degree beam angle the light spreads broadly rather than as a narrow spot, lifting a room evenly from a single point. As an LED it replaces a 40W old-style bulb while using a fraction of the power.

Use it anywhere a general-purpose household bulb is needed indoors, in table and floor lamps, pendants, wall fittings and ceiling roses across living rooms, bedrooms and hallways. The wide 180 degree spread and warm 2700K tone make it best for ambient and accent light rather than tight task work, casting a comfortable glow across a seating or reading corner. With a colour rendering of Ra 90 it shows skin tones, fabrics and timber accurately, so furnishings keep their true colour. Being a dry indoor bulb it is for interior use only and should be kept clear of bathrooms, porches and any damp or exposed location.

The bulb measures Ø60 by 107 mm and weighs just 28 g, a compact unit that sits neatly in shaded and open fittings alike. It runs on 220 to 240V AC mains through the E27 screw cap, with no separate driver or transformer needed. Efficiency is rated at 138 lm/W and the bulb is non-dimmable, so pair it with a standard on/off switch rather than a dimmer. Rated for 25,000 hours, it holds its warm white output over a long service life, with a plain white finish on the diffuser.

Product Specification Sheet

Range Datasheet

Which fitting does this bulb need?

It has an E27 Edison Screw (ES) cap, the larger screw fitting found on many lamps, pendants and ceiling roses. In the US this is the standard medium screw base. Simply twist it into any matching E27 holder, no adaptor required.

What old bulb wattage does it replace?

The LED itself draws only 3.4W but gives out 470 lumens, so it replaces a 40W old-style incandescent bulb. You get a similar level of warm light for a small fraction of the running cost. Rated efficiency is 138 lm/W.

Is this bulb dimmable?

No, this is a non-dimmable bulb, so it should be used with a standard on/off switch rather than a dimmer circuit. Pairing it with a dimmer can cause flicker or buzzing. If you need adjustable brightness, choose a bulb marked dimmable.

What colour of light does it give?

It produces a warm white tone at 2700K, the soft, cosy colour suited to living rooms and bedrooms. With a colour rendering of Ra 90 it shows colours accurately, keeping fabrics and timber looking natural. The 180 degree beam spreads the light broadly for even ambient cover.
