Energizer 24.9W LED GLS Bulb E27 6500K Daylight - 3452lm Non-Dimmable

The Energizer 24.9W LED GLS bulb delivers 3452 lumens at 6500K daylight colour temperature through a standard E27 Edison screw base. The bulb replaces 200W incandescent equivalents while consuming 24.9W, providing bright, cool-toned light suited to task-focused environments where clarity and visibility matter.

Designed for kitchens, garages, workshops, utility rooms and office spaces, the 6500K daylight output produces a crisp, blue-white light that supports detailed work and reduces eye strain during prolonged tasks. The GLS (General Lighting Service) shape fits standard lampholders and shades designed for traditional bulbs, and the 60mm diameter matches the footprint of most domestic and commercial light fittings. The bulb is non-dimmable and operates on standard 230V UK mains.

The Energizer LED carries a 15-year rated lifespan based on average domestic use patterns, reducing replacement frequency compared to shorter-life alternatives. The bulb measures 128mm in height and 60mm in diameter, making it compatible with most enclosed and open fittings that accommodate standard GLS bulbs. The daylight colour temperature differs noticeably from warm white (2700K-3000K) bulbs — it produces a cooler, more clinical light that some users prefer for functional spaces and others find too stark for living areas.

Is this bulb dimmable?

No. The Energizer 24.9W LED GLS is non-dimmable and will flicker or fail if used with a dimmer switch. For dimmable options, search for bulbs marked as dimmable-compatible in the same wattage and base type.

What does 6500K daylight mean in practice?

6500K produces a cool, blue-white light similar to midday sunlight or overcast daylight. It appears noticeably cooler and more clinical than the warm yellows of 2700K-3000K bulbs commonly used in living rooms and bedrooms. Most users choose 6500K for garages, workshops and task lighting rather than ambient home lighting.

What's the actual energy consumption compared to a 200W incandescent?

This bulb consumes 24.9W to produce the same 3452 lumens output as a traditional 200W incandescent. Over a year of typical use (3 hours per day), that's approximately 27kWh versus 219kWh — saving around 192kWh annually per bulb.

Will it fit in enclosed fittings?

The 128mm height and 60mm diameter match standard GLS bulb dimensions, so it fits most enclosed pendant shades, ceiling flush fittings and table lamp bases designed for traditional bulbs. Check your fitting's internal clearance if using a particularly tight or shallow shade.
