JCB 14W Non-Dimmable LED GLS Bulb E27 - 6500K Daylight

The JCB 14W LED GLS bulb is a standard E27 screw-fit replacement bulb delivering 1521 lumens at 6500K daylight colour temperature. The 14W power draw makes it equivalent to a traditional 100W incandescent in light output, with a 180-degree beam angle that suits general room lighting, ceiling pendants and table lamps.

Designed for spaces where crisp, cool light aids focus and visibility, the 6500K temperature suits home offices, workshops, garages, utility rooms and commercial environments where task clarity matters more than ambient warmth. The non-dimmable design provides consistent output without flicker, making it suitable for prolonged use in reading lights, desk lamps and fixed ceiling fittings where dimmer control is not required.

The GLS (General Lamp Service) shape is the classic A60 bulb profile recognised worldwide, fitting any standard E27 socket from vintage table lamps to modern ceiling shades. At 60mm diameter and 120mm height, the bulb sits within the envelope of most shades and diffusers designed for traditional incandescent or halogen GLS bulbs. The frosted finish diffuses the LED chips inside to provide even light distribution without visible hot spots.

JCB rates this bulb at Energy Rating F under the revised UK/EU energy label scale introduced in 2021. While this sits mid-range on the new scale, the 14W consumption for 1521 lumens represents an 86% energy saving over a 100W incandescent delivering comparable output, reducing running costs over the bulb's operational life.

Is this bulb dimmable?

No. This JCB bulb is non-dimmable. Attempting to use it with a dimmer switch may cause flickering, buzzing or premature failure. If dimming is required, check for dimmable variants in the JCB LED range.

What is 6500K daylight suited for?

6500K produces a cool, blue-white light that mimics midday sunlight. It aids concentration and colour accuracy, making it well-suited to home offices, workshops, garages and task areas. It is less suited to living rooms or bedrooms where warmer 2700K-3000K tones create a more relaxed atmosphere.

What is the lifespan of this bulb?

While the specification does not list rated hours, JCB LED bulbs in this series typically offer 10,000-15,000 hours of operation. At 3 hours daily use, this translates to approximately 9-13 years before replacement is needed.

Will it fit my existing lamp?

The E27 Edison screw base is the standard large screw fitting used across most UK, European and international domestic lighting. The 60mm diameter and 120mm height match traditional GLS bulb dimensions, so it will fit any shade, pendant or lamp designed for a standard bayonet or screw bulb.
