Description
The JCB 8.5W LED GLS bulb is a direct replacement for traditional 60W incandescent bulbs, delivering 806 lumens from an 8.5W LED filament behind a frosted glass envelope. The B22 bayonet cap fits standard UK light fittings including ceiling pendants, table lamps, bedside lights and wall sconces without requiring adapters or special sockets.
The 3000K warm white colour temperature produces a soft yellow-toned light comparable to traditional incandescent bulbs, making it suitable for living rooms, bedrooms, dining rooms and hallways where a warmer ambient tone is preferred over cooler daylight whites. The 180-degree beam angle provides omnidirectional light distribution, filling shades and diffusers evenly without creating shadowed zones.
This is a non-dimmable bulb and must not be used with dimmer switches or dimming circuits — attempting to dim it may cause flickering or premature failure. The GLS (General Lighting Service) shape is the classic pear-shaped bulb profile measuring 60mm diameter by 110mm height, fitting inside most lamp shades and pendant fittings designed for standard bulbs. The bulb carries an Energy Rating of F under the current UK energy labelling scale.
JCB markets this bulb under the "Built to Last" claim with a stated lifespan of up to 10 years based on average household usage patterns. The bulb operates on 220-240V mains voltage and switches on instantly to full brightness without warm-up delay.

Frequently Asked
Can this bulb be used with a dimmer switch?
No. This is a non-dimmable LED bulb and must not be connected to dimmer circuits or dimmer switches. Using it with a dimmer may cause flickering, buzzing or premature failure.
What wattage incandescent bulb does this replace?
The 8.5W LED output of 806 lumens is equivalent to a traditional 60W incandescent bulb, providing comparable brightness while using approximately 86% less energy.
What is the colour of the light?
The bulb emits 3000K warm white light, which appears as a soft yellow-toned glow similar to traditional incandescent bulbs. This is warmer than daylight whites (4000K+) and cooler than very warm vintage-style bulbs (2200K-2700K).
Will it fit my existing lamp?
The B22 bayonet cap is the standard UK bulb fitting. If your existing lamp or ceiling fitting accepts a traditional bayonet bulb, this will fit directly. The GLS shape (60mm diameter, 110mm height) is the classic pear-shaped bulb profile and fits most standard lamp shades and pendant fittings.
