Energizer 4.2W Dimmable GLS LED Bulb B22 Cool White 4000K

Description

The Energizer 4.2W GLS LED bulb delivers 470 lumens of 4000K cool white light through a standard B22 bayonet cap fitting. Designed as a direct replacement for traditional 40W incandescent GLS bulbs, it draws just 4.2W while providing equivalent light output. The classic GLS shape gives 270-degree light distribution, making it suitable for table lamps, ceiling pendants and wall lights where general ambient illumination is needed.

Dimmable functionality allows brightness to be adjusted from full 470 lumens down to around 10% output, depending on the dimmer switch installed. This makes the bulb adaptable for kitchens and workspaces needing task lighting during the day, and living rooms or bedrooms where lower evening light levels are preferred. The 4000K colour temperature sits between warm white and daylight, giving neutral white light that renders colours accurately without the yellow cast of 2700K bulbs or the blue tint of 65
