Description

The Energizer 4.2W LED GLS is a B22 bayonet-fitting bulb delivering 470 lumens of 2700K warm white light. The bulb replaces a traditional 40W incandescent while consuming just 4.2W, and is fully dimmable when paired with compatible dimmer switches, allowing light levels to be adjusted from full brightness down to a low glow.

Designed for table lamps, ceiling pendants, wall lights and any fitting with a B22 bayonet socket, the GLS (General Lighting Service) shape is the classic bulb profile that fits most domestic lampholders. The 2700K colour temperature produces a warm, yellowish-white light that suits living rooms, bedrooms and dining areas where a cosy tone is preferred over cooler daylight-spectrum LEDs.

The bulb carries a 15-year lifespan rating based on average domestic usage patterns, reducing the frequency of replacements compared to halogen or incandescent bulbs. The frosted glass envelope diffuses the LED chip
