Energizer 7W Dimmable LED GLS Filament Bulb B22 2700K Warm White

The Energizer 7W LED GLS filament bulb pairs a traditional glass globe shape with visible LED filament strips that mimic the look of tungsten wire, delivering 806 lumens of warm white 2700K light from a B22 bayonet cap fitting. The bulb draws 7W on mains power, providing an equivalent output to a 60W incandescent while running cooler and lasting longer.

Designed for table lamps, pendant fittings, wall lights and ceiling fixtures across living rooms, bedrooms and dining rooms, the bulb's dimmable function works with most trailing-edge and leading-edge dimmer switches installed in UK homes. Dimming range varies by dimmer model, but most achieve smooth transitions from 10-100% brightness without flicker or hum. The B22 bayonet cap fits standard UK lamp holders with a quarter-turn twist-lock action.

The 60mm diameter globe and 109mm overall height suit most shaded table lamps and exposed-bulb pendant fittings where the bulb remains visible. The clear glass envelope allows the filament strips to be seen when the bulb is on or off, giving a warmer visual appearance than opaque white LED bulbs. The 320-degree beam angle distributes light in all directions except directly behind the bayonet cap, making it suitable for general room lighting rather than focused task lighting.

Energizer rates this bulb at 15,000 hours lifespan under typical domestic use, equating to approximately 15 years at 3 hours per day. The energy rating of E reflects the efficiency of LED technology relative to older halogen and incandescent equivalents, consuming 88% less energy than a 60W tungsten bulb producing similar lumens.

Is this bulb compatible with dimmer switches?

Yes. The bulb is rated as dimmable and works with most trailing-edge and leading-edge dimmer switches. Dimming performance varies by dimmer model — some older rotary dimmers may cause low-level flicker or have a narrower dimming range. For best results, use a dimmer rated for LED loads.

What colour temperature is 2700K?

2700K is warm white, matching the colour temperature of traditional incandescent bulbs. It produces a yellowish-white light with a slight orange cast, creating a warm and relaxed atmosphere suitable for living rooms, bedrooms and dining areas.

How long does the bulb last?

Energizer rates this bulb at 15,000 hours lifespan, equivalent to approximately 15 years at 3 hours per day of use. Actual lifespan depends on usage patterns and whether the bulb is frequently switched on and off.

Will it fit my lamp holder?

The B22 bayonet cap fits standard UK lamp holders found in most table lamps, pendant fittings, wall lights and ceiling fixtures. It uses a quarter-turn twist-lock fitting. The 60mm diameter and 109mm height suit most shaded and exposed-bulb fixtures, but check your fitting's internal clearance if the shade sits close to the bulb.
