Eveready 13.8W LED GLS Bulb E27 3000K Warm White - 1521lm Non-Dimmable (2 Pack)

The Eveready 13.8W LED GLS bulb produces 1521 lumens from a standard E27 Edison screw fitting, delivering the light output of a 100W incandescent bulb while consuming 86% less energy. The warm white 3000K colour temperature provides a yellow-toned light suited to living rooms, bedrooms, dining areas and hallways where ambient lighting is needed rather than cool task light.

Designed as a direct retrofit for traditional 100W incandescent GLS bulbs, the Eveready LED fits standard table lamps, ceiling pendants, and wall lights with E27 lamp holders. The 200-degree beam angle provides wide light distribution across a room rather than a focused spotlight effect. The bulb is rated for 15,000 hours of operation, which translates to approximately 10 years of use at an average 4 hours per day, reducing the frequency of replacement compared to halogen or incandescent alternatives.

The GLS (General Lighting Service) shape measures 60mm in diameter and 119mm in height, matching the profile of traditional incandescent bulbs so the LED sits within existing lampshades and fittings without protruding. The frosted white finish diffuses the LED chip array inside, giving an even glow rather than visible point sources when the bulb is on. Each bulb weighs 70g, making the 2-pack suitable for lighter ceiling pendants and adjustable desk lamps without overloading the fitting.

This is a non-dimmable bulb and should not be paired with dimmer switches — doing so can cause flicker, reduced lifespan, or failure. The Energy Rating E classification reflects current UK energy labelling standards introduced in 2021, where the scale was rescaled and most LED bulbs now fall between D and G rather than the previous A++ to E scale.

Can this bulb be used with a dimmer switch?

No. This bulb is non-dimmable and must not be used with dimmer switches. Pairing with a dimmer can cause flicker, humming, reduced lifespan or complete failure of the bulb.

What incandescent wattage does this replace?

The 1521-lumen output is equivalent to a 100W traditional incandescent bulb, while consuming only 13.8W of power. This makes it suitable for rooms where you previously used 100W incandescent or 20W halogen bulbs.

How long does the bulb last?

The bulb is rated for 15,000 hours of operation. At 4 hours of use per day, this equates to approximately 10 years before replacement is needed.

Will it fit my existing lamp or fitting?

The bulb has a standard E27 (Edison screw) base that fits most UK and European table lamps, ceiling pendants and wall lights. The 60mm diameter and 119mm height match traditional GLS bulb dimensions, so it will sit within most existing lampshades without protruding.
