E27 GLS LED Bulb 11W 100W-eq 1521lm A60 180° - Cool White

This E27 GLS LED bulb is a classic A60 household lamp, the familiar rounded shape that fits the most common screw-fitting lights. The cap is E27 Edison Screw, known as ES, so it twists straight into standard pendants, lamps and ceiling fittings. It draws just 11W while giving 1521 lumens, a replacement for an old 100W incandescent bulb at a fraction of the running cost. The light is 4000K cool white, a crisp neutral tone, and the 180 degree beam spreads light broadly rather than directing it, much like a traditional bulb. In US terms this is an A19-style household LED.

This bulb suits everyday fixtures around the home where a bright, even light is wanted: living room and hallway pendants, bedside and table lamps, landing fittings and enclosed shades. The wide 180 degree spread and 1521 lumen output make it well suited to open shades and central room fittings, lifting overall brightness without harsh shadows. The cool white 4000K tone reads as clean and practical, working well in kitchens, home offices and utility spaces where clarity matters more than a warm cosy feel. It is rated IP20 for dry indoor use only, so keep it to interior fittings rather than porches, bathrooms or anywhere damp.

The bulb measures 60mm in diameter and 120mm long, weighing 40g, with a white finish to the body. It runs on 220 to 240V AC mains, delivering 138 lm/W efficiency and an Ra 90 colour rendering figure for accurate, true-looking colours. Rated for 25,000 hours, it is built to last far longer than the halogen or incandescent lamps it replaces. Please note this bulb is non-dimmable, so it should be used with standard on/off switching rather than a dimmer circuit.

Product Specification Sheet

Range Datasheet

Which fitting do I need for this bulb?

It has an E27 Edison Screw cap, often called ES, which is the larger screw fitting found on most standard pendants and lamps. You simply twist it into the holder. The A60 shape is the classic rounded household form, so it fits enclosed and open shades alike.

What old bulb wattage does this replace?

At 11W it gives 1521 lumens, which matches the brightness of an old 100W incandescent bulb. The LED itself only draws 11W, so you get the same light for far less energy. Over its 25,000 hour life that adds up to a meaningful saving.

Is this a warm or cool light?

It is 4000K cool white, a crisp neutral tone that sits between warm white and daylight. This suits kitchens, offices and utility areas where clear, practical light is wanted. With Ra 90 colour rendering, colours look natural and accurate under it.

Can this bulb be dimmed?

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