Description

The JCB 4.9W LED GLS bulb is a B22 bayonet cap fitting that produces 470 lumens of 6500K daylight white light, positioned as a direct replacement for traditional 40W incandescent GLS bulbs. The 60mm diameter and 110mm height match the dimensions of a standard GLS (General Lighting Service) bulb, allowing it to fit existing ceiling pendants, table lamps and wall lights without modification.

Designed for task lighting, home offices, kitchens and utility spaces where bright, cool-toned light supports concentration and visibility, the 6500K colour temperature sits at the daylight end of the spectrum. This makes the bulb suitable for work benches, garage lighting, laundry rooms and commercial environments where colour rendering and clarity matter more than warmth. The non-dimmable design maintains consistent output on standard on/off switching without flicker.

The bulb consumes 4.9W to produce 470 lumens, giving an efficacy of approximately 96 lumens per watt and an 88% reduction in energy use compared to the 40W incandescent it replaces. The F energy rating reflects the regulatory classification under current EU/UK energy labelling rules. JCB rates the bulb for 10,000 hours of operational life and backs it with a 3-year manufacturer warranty.

Frequently Asked

Is this bulb dimmable?

No. This is a non-dimmable LED bulb designed for on/off switching only. Attempting to use it with a dimmer switch may cause flicker, reduced lifespan or failure to light.

What colour is the light?

The bulb produces 6500K daylight white light, which appears cool, bright and slightly blue-toned compared to warm white or neutral white LEDs. This colour temperature suits task lighting and commercial environments more than living rooms or bedrooms where warmer tones are typically preferred.

What is the B22 fitting?

B22 is the UK bayonet cap fitting with two locating pins on a 22mm diameter base. It pushes into the socket and twists to lock, and is the standard bulb fitting in most UK homes built before the 2000s.

How long does it last?

JCB rates this bulb for 10,000 hours of operation, which translates to approximately 10 years of use at 3 hours per day. The bulb carries a 3-year manufacturer warranty.
