B22 (BC) LED GLS Bulb 7.2W 1521lm Non-Dimmable - Warm White 2700K

This is a B22 bayonet cap LED bulb in the classic GLS shape, the rounded pear form that has been the standard household bulb for decades. It draws 7.2W and gives 1521lm, which is a bright output for a general purpose lamp, and the colour temperature is 2700K warm white. Inside the clear glass envelope sit slim filament strands rather than a diffused dome, so the light source stays on show and the bulb keeps the look of the incandescent it stands in for. The manufacturer rates it energy class A, and the label quotes 8kWh per 1000 hours.

Because the filament is the part you see, this suits fittings where the bulb is on show: an open pendant, a bare flex and ceiling rose, or a table lamp with a wide shade opening. Bayonet caps remain common in UK pendants, so it is often a straight swap for an older bulb. Check the old cap first: B22 has two pins on the side and pushes in with a quarter turn, while a screw cap is threaded and takes an E27 instead. At 1521lm it is bright enough to be the only light in a hallway, a landing or a good sized living room, and 2700K keeps that brightness soft rather than clinical.

This bulb is not dimmable, and the pack marks that with a crossed out dimmer icon, so pair it with a plain on and off switch rather than a rotary or trailing edge dimmer. The pack states a 100W replacement and a 50 year lifespan. Each box holds one bulb, and this listing carries a minimum order of 12, sold in multiples of 12, which suits relamping a whole house or keeping spares in the cupboard. We also stock LED bulbs in B15 candle and GU10 fittings.

How do I know if my light takes a B22 cap?

Look at the base of the old bulb. B22 has two small pins on the sides of a smooth metal cap and pushes in with a quarter turn, where a screw cap has a spiral thread and winds in.

Is 1521 lumens bright enough to replace an old 100W bulb?

The pack states a 100W replacement, and at 1521lm this is one of the brighter GLS lamps, so it works well as the single ceiling light in a hallway, landing or living room.

Can I use it on a dimmer switch?

No. The specification and the pack both mark it non dimmable, so it needs a plain on and off switch. On a dimmer circuit it may flicker, buzz or fail early.

What does 2700K warm white actually look like?

It is the soft yellow tone people associate with old filament bulbs, warmer than the 4000K cool white used in kitchens and utility spaces, and it flatters wood, brick and warm paint colours.

Does the manufacturer give an IP rating for this bulb?

No IP rating is stated in the specification or printed on the pack, so there is no figure for us to quote. Where a fitting's instructions call for a rated lamp, choose one that states a rating.

How many bulbs will I receive?

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