Eveready 13.8W E27 LED GLS Bulb 1521lm Daylight 6500K Non-Dimmable

The Eveready 13.8W E27 LED GLS bulb produces 1521 lumens at a daylight 6500K colour temperature, drawing 13.8W to replace a 100W incandescent bulb. The E27 Edison screw base fits standard UK lamp holders in ceiling pendants, table lamps and wall lights, while the GLS (General Lighting Service) shape matches the profile of traditional filament bulbs.

The 6500K daylight output suits task lighting in home offices, workshops, garages and utility rooms where crisp white light aids concentration and colour accuracy. The 200-degree beam angle distributes light broadly across a room rather than focusing it into a narrow spot, making the bulb suitable for general overhead lighting in kitchens, hallways and bathrooms. The non-dimmable design means the bulb operates at full brightness on standard switched circuits.

Rated at 10,000 hours of operation, the bulb is designed to last approximately 10 years under average domestic use (around 3 hours per day). The frosted polycarbonate diffuser spreads light evenly without visible LED chips or hotspots. At 60mm diameter and 119mm height, the bulb fits within the shade depth of most table lamps and pendant fittings designed for standard GLS bulbs.

The Energy Rating E classification reflects the shift in EU energy labelling introduced in 2021, where LEDs that previously held A+ or A ratings were recalibrated onto a stricter A-G scale. An E-rated LED still delivers approximately 87% energy savings compared to the 100W incandescent it replaces, reducing running costs while maintaining equivalent light output.

Is this bulb dimmable?

No. The bulb is non-dimmable and will flicker or fail if used with a dimmer switch. For dimmable E27 GLS LEDs, search the Niori catalogue for bulbs specifically marked as dimmable.

What does 6500K daylight mean?

6500K is a cool white colour temperature that mimics natural daylight at midday. It renders colours more accurately than warm white (2700K-3000K) and is often chosen for task lighting in workspaces, garages and areas where visual clarity matters. It can feel too clinical for living rooms or bedrooms where warmer tones are preferred.

Will this bulb fit my existing lamp?

If your lamp or fitting currently uses a standard screw-in bulb with an E27 base (the common Edison screw), this bulb will fit. At 60mm diameter and 119mm height, it matches the size of a traditional 100W incandescent GLS bulb, so it should fit within most shades and diffusers designed for that shape.

How long will the bulb last?

The bulb is rated at 10,000 hours. Under average domestic use of around 3 hours per day, this translates to approximately 10 years of operation before the LED output degrades below 70% of its original brightness.
