E27 GLS LED Bulb 11W 100W-eq 1521lm 180° - Warm White

This E27 GLS LED bulb takes the classic rounded A60 household shape, the everyday form most table lamps, pendants and ceiling fittings are built around. It draws just 11W yet puts out 1521 lumens, enough to stand in for an old 100W bulb without the heat or running cost. The light is a warm white 2700K, the soft yellow-toned glow most people associate with living spaces, and it spreads across a wide 180 degree beam so the output reaches across a room rather than firing in one direction. The E27 cap is the standard Edison Screw fitting, known in the United States as a medium screw base, so it threads straight into the fittings you already own.

The wide 180 degree spread and high 1521 lumen output make this a general-purpose bulb for living rooms, bedrooms, landings and hallways, working equally well behind a shade or in an open pendant where its even fill lights the whole space rather than throwing a tight pool. The 2700K tone keeps relaxed areas feeling warm in the evening, while the strong lumen figure means a single bulb can carry a smaller room or pair up in a multi-lamp fitting for a larger one. As an IP20 bulb it is for dry indoor use only, so keep it clear of bathrooms, porches and any outdoor or damp location.

Built on the standard A60 envelope measuring 60mm across and 120mm long, the bulb weighs only 40g and runs on 220 to 240V AC mains through its E27 base. Colour rendering is rated Ra90, a high figure that keeps skin tones, fabrics and decor looking true under the light. It is rated for 25,000 hours of life at an efficiency of 138 lumens per watt. This bulb is non-dimmable, so it is best paired with a standard non-dimming switch. The finish is a plain white diffused body that suits any fitting.

Product Specification Sheet

Range Datasheet

What fitting does this bulb need?

It has an E27 cap, the standard Edison Screw base often abbreviated to ES. It threads straight into any E27 holder, the most common screw fitting on table lamps, pendants and ceiling fittings in the UK.

What old bulb wattage does it replace?

At 1521 lumens it replaces a 100W traditional incandescent bulb while drawing only 11W itself. You get the same brightness for a fraction of the running cost, with a rated life of 25,000 hours.

Is the light warm or cool?

It is a warm white 2700K, the soft yellow-toned glow suited to living rooms, bedrooms and other relaxing spaces. Its Ra90 colour rendering also keeps colours in the room looking natural and true.

Can this bulb be dimmed?

No, this is a non-dimmable bulb, so it should be used with a standard on/off switch rather than a dimmer. Pairing a non-dimmable bulb with a dimmer can cause flicker or buzzing and may shorten its life.
