Description

The Energizer 12.6W E27 LED GLS bulb delivers 1521 lumens of 6500K daylight white light in a standard A60 globe shape. The E27 Edison screw base fits most UK domestic light fittings designed for traditional incandescent bulbs, while the 12.6W consumption replaces 100W incandescent equivalents with an 87% reduction in energy use. The bulb operates on 230V mains and is non-dimmable.

Designed for spaces requiring bright, cool-toned light — home offices, kitchens, garages, workshops, utility rooms — the 6500K colour temperature mimics natural daylight rather than the warmer tones typically used in living rooms or bedrooms. The 240-degree beam angle distributes light widely across the room without creating a narrow spotlight effect. At 122mm tall and 60mm diameter, the bulb fits inside most ceiling pendants, table lamp shades and wall-mounted fixtures without protruding beyond standard shade rims.

Energizer rates this bulb for a 15-year lifespan based on average domestic usage of 2.7 hours per day, which translates to approximately 15,000 hours of continuous operation before failure. The GLS (General Lighting Service) shape maintains the familiar rounded profile of traditional incandescent bulbs, so it works visually in exposed-bulb fixtures where the bulb itself forms part of the aesthetic. The frosted glass diffuser softens the LED array inside and prevents visible diode hotspots when the bulb is viewed directly.

Frequently Asked

Is this bulb dimmable?

No. This Energizer GLS bulb is non-dimmable and will not function correctly with dimmer switches. Installing it on a dimmed circuit may cause flickering or premature failure. Use a standard on/off switch only.

What colour is the light — warm or cool?

This bulb produces 6500K daylight white, which is a cool, bright tone similar to natural midday light. It is not warm white. For warmer, more relaxing tones in living rooms or bedrooms, look for bulbs rated 2700K-3000K instead.

How bright is 1521 lumens?

1521 lumens is equivalent to a traditional 100W incandescent bulb. This makes it suitable for larger rooms, kitchens, workshops or any space where high brightness is needed.

Will it fit in a standard lampshade?

Yes. The bulb measures 60mm in diameter and 122mm tall, which is the standard GLS/A60 size used in most UK lampshades, ceiling pendants and table lamps designed for traditional bulbs.
