Description

The Energizer 5W LED GLS filament bulb uses a B22 bayonet cap fitting and delivers 550 lumens of 2700K warm white light through visible filament strips inside a clear glass envelope. The bulb draws 5W on 230V mains, replacing traditional 40W incandescent bulbs with equivalent light output at an eighth of the power consumption.

Designed for table lamps, ceiling pendants, wall sconces and any fitting that accepts a standard B22 bayonet bulb, the GLS shape sits 109mm tall with a 60mm diameter globe. The visible filament design gives the bulb a vintage aesthetic when lit or unlit, pairing well with open-shade fittings, industrial pendants and decorative fixtures where the bulb is visible. The 320-degree beam angle provides wide, omnidirectional light distribution suitable for general ambient lighting rather than directed task lighting.

The bulb is dimmable when paired with compatible LED dimmer switches, allowing light levels to be adjusted from full brightness down to a low glow depending on the time of day or room use. Energy Rating E indicates moderate efficiency within the current EU labelling scale, balancing the warm colour temperature and filament design with power consumption. The clear glass envelope and exposed filament strips create a warm amber glow at 2700K that softens as the bulb dims.

Frequently Asked

Is this bulb dimmable?

Yes. The bulb is rated as dimmable and works with compatible LED dimmer switches. Dimmer compatibility varies by manufacturer — test with your existing dimmer or contact us for recommendations if you're unsure.

What's the difference between B22 and E27?

B22 is a bayonet cap with two pins that twist and lock into the fitting. E27 is an Edison screw base that threads in. This bulb uses B22, the standard bayonet fitting common in UK residential lighting.

How bright is 550 lumens?

550 lumens is equivalent to a traditional 40W incandescent bulb, providing enough light for bedside lamps, hallway fittings, or accent lighting in living rooms. It's ambient rather than task lighting.

What does 2700K mean?

2700K is the colour temperature measured in Kelvin. It produces a warm white light with a slight amber tone, similar to traditional incandescent bulbs. Higher numbers (4000K, 6000K) give cooler, bluer light.
