The Energizer LED GLS B22 470lm 4.2W 2700K (Warm White) Light Bulb – Pack of 4 is a smart and dependable choice for lighting across a range of domestic and light commercial settings. Combining traditional design with the efficiency and reliability of modern LED technology, this pack of four bulbs is perfect for anyone looking to refresh their lighting with long-lasting, consistent performance.
Each bulb in the pack emits 470 lumens of light while using only 4.2 watts of power, offering the brightness equivalent to a 40W incandescent bulb. The warm white light, rated at 2700K, produces a soft, welcoming glow that’s especially suited to living rooms, bedrooms, dining areas, hallways, and other spaces where comfort and relaxation are a priority. It adds a cosy, atmospheric quality that complements both modern and classic interiors.
The familiar GLS (General Lighting Service) bulb shape has been a standard in households for generations. It remains one of the most versatile formats for home lighting, fitting seamlessly into ceiling pendants, wall-mounted fixtures, bedside table lamps, and free-standing floor lamps. The B22 bayonet cap—widely used in the UK—ensures compatibility with a broad range of fittings. Installation is straightforward: simply push and twist the bulb into place, with no need for tools or technical adjustments.
These bulbs are designed to switch on at full brightness immediately—no flickering, warming up, or delays. This is particularly useful in areas where instant illumination is important, such as bathrooms, staircases, entrances, or kitchens. The frosted finish on the bulbs helps to disperse the light evenly, reducing glare and harsh shadows. This leads to a more balanced distribution of light and an overall softer effect that’s easier on the eyes.
The bulbs are non-dimmable, offering a fixed and steady level of brightness ideal for general lighting purposes. This consistency makes them suitable for everyday use throughout the home, in spaces where adjustable lighting is not required. Whether you’re reading, dining, or simply relaxing, these bulbs offer a comfortable and stable light source.
Constructed with long-term use in mind, each bulb is designed to perform reliably over an extended period, depending on the frequency of use. This long life expectancy helps to minimise the need for frequent replacements, making them a practical choice for high ceilings or awkward-to-reach fittings where regular changes would be inconvenient.
With a Colour Rendering Index (CRI) of 80 or higher, these bulbs ensure that colours appear natural and true to life. This is a particularly valuable feature in rooms where aesthetics matter, such as living spaces, studies, or areas used for hobbies and creative work.
As part of the Energizer lighting range, these bulbs reflect the brand’s commitment to delivering high-quality and dependable home lighting solutions. Rigorously tested for safety and performance, they provide users with confidence and peace of mind. Whether you're replacing older bulbs, upgrading fixtures, or fitting out a new space, the Energizer LED GLS B22 4.2W bulbs offer a practical blend of classic design and modern efficiency.
