Energizer LED GLS Bulb B22 (BC) 12.6W Opal Dimmable - Warm White 2700K

This is a 12.6W LED GLS bulb with a B22 bayonet cap, the classic pear-shaped household lamp on the fitting that twists and locks with two pins rather than screwing in. It gives 1521 lumens, which the pack sets against a 100W filament bulb, so it is one of the brighter LED replacements rather than a standard 60W stand-in. The light is 2700K warm white, the softer yellow end of the white range, and the lamp is dimmable. The bulb is opal rather than clear, so the light is diffused across the whole surface instead of showing as bright points.

Those 1521 lumens make this a lot of light for a single lamp, so it suits the places where one fitting does all the work: a kitchen pendant, a hallway, a landing, or a living room ceiling rose that has to cover the whole floor. B22 is the older British bayonet standard and is still fitted to many pendant sets and ceiling roses; if the cap on the bulb you are removing is smooth metal with two small pins on the side, this is the one you want. At 2700K the light reads warm against wood, cream paint and plaster, and the opal bulb keeps the source from glaring through a thin fabric shade.

Dimming is the reason to choose this version over a fixed-output lamp, and both the specification and the pack confirm it. Pair it with a dimmer rated for LED loads: a 12.6W lamp draws a small fraction of the current an older filament dimmer was built to see, which is what causes flicker at the bottom of the dial. The pack prints a 15 year lifespan and 15,000 hours, and an energy rating of E. Each box holds one bulb, and the minimum order is 12, sold in multiples of 12. It sits alongside our wider range of LED bulbs in other fittings, including B15 (SBC) candle and golf lamps and GU10 spotlights.

Will this fit my existing light fitting?

It takes a B22 bayonet holder. Look at the cap on the old bulb: if it is smooth metal with two small pins on the sides and it pushes in and turns a quarter to lock, this is the right fitting. A threaded screw cap is an E27 and will not take this lamp.

How bright is 1521 lumens in practice?

The pack rates it as a 100W replacement, so it is brighter than the usual 60W equivalent LED most people buy. That makes it a good choice where one central pendant has to light an entire kitchen, hall or living room on its own.

Can I use it with a dimmer switch?

Yes, both the specification and the pack confirm the lamp is dimmable. Use a dimmer designed for LED loads, because a 12.6W lamp draws far less current than the filament bulbs older dimmers were built around, and a mismatch shows up as flicker or a short dimming range.

What does 2700K warm white actually look like?

It is the warm, slightly yellow light people associate with old filament bulbs, rather than the crisp blue-white of a 4000K or 6500K lamp. It flatters wood, cream and warm paint colours and suits rooms meant to feel relaxed in the evening.

Is an IP rating given for this bulb?

No IP figure is printed on the retail pack or listed in the manufacturer's specification, so we do not quote one. Where a rating matters for a particular fitting, check the rating printed on the fitting itself.

How many bulbs do I receive?

Each box contains one bulb. The minimum order on this listing is 12 boxes, sold in multiples of 12, so a first order brings you twelve single-bulb boxes.
