B22 (BC) LED GLS Bulb 18W 2452lm Non-Dimmable - Warm White 2700K

This is a bayonet cap LED bulb in the classic GLS shape, drawing 18W and giving 2452 lumens of light. That output sits at the top end of what a household bulb produces: the pack rates it as a replacement for a 150W incandescent, so it is the one to reach for when a single central fitting has to light a whole room on its own. The cap is B22, the two pin bayonet type you push in and twist a quarter turn, and the shape is the familiar rounded pear outline of a GLS lamp, with a white body rather than clear glass.

Because of the output, it earns its place where the old 100W and 150W bulbs used to go: a large living room or open plan kitchen on a single pendant, a hallway or landing with one ceiling rose, a garage, a workshop or a loft where you want to see what you are doing. At 2700K the light is warm white, the yellow toned light people associate with traditional filament bulbs, so plenty of brightness arrives without the clinical feel a daylight lamp brings to a living space. It suits open pendants, standard lamps and uplighters that take a B22 cap.

There is no dimming here: the pack marks the bulb non dimmable, so put it on a plain on and off switch rather than a dimmer circuit, where a non dimmable LED can flicker or buzz. The energy label reads class D, and the pack prints a 15 year lifespan. Each box holds one bulb, and the listing has a minimum order of 12, sold in multiples of 12, which suits fitting out a whole house or keeping spares on the shelf. It sits alongside our wider range of LED bulbs in B15, GU10 and E27 fittings, including candle and golf shapes in warm white and cool white.

Will this fit my existing bayonet light fitting?

It takes a B22 bayonet cap, so check the old bulb has two small pins on the side of a metal cap rather than a screw thread. If it pushes in and twists a quarter turn to lock, this is the right cap.

How bright is 2452 lumens in practice?

It is at the bright end of household lamps. The pack rates it as a 150W replacement, so one bulb can carry a large living room, a hallway or a garage where a 60W equivalent would leave corners dim.

Can I use it on a dimmer switch?

No. The pack marks it non dimmable, so it should go on a plain on and off switch. Non dimmable LEDs fitted to a dimmer circuit can flicker, buzz or fail to strike at low settings.

What does 2700K warm white actually look like?

It is the soft yellow toned light of a traditional filament bulb, comfortable in living rooms and bedrooms. If you want the crisp blue white of a daylight lamp, you want a higher Kelvin figure instead.

Is an IP rating given for this bulb?

The manufacturer prints no IP rating on the pack, so treat it as an ordinary indoor lamp for dry domestic fittings and use a rated fitting where any protection from moisture is needed.

How many bulbs do I receive, and how many must I order?

One box contains a single bulb. The minimum order on this listing is 12 units, sold in multiples of 12, which works well for a full house change or a run of spares.
