B22 (BC) LED GLS Bulb 7.3W 806lm Dimmable - Cool White 4000K

This is a standard GLS bulb, the classic pear shaped lamp that most UK ceiling pendants, table lamps and shades were built around. It takes a B22 bayonet cap, the push and twist fitting with two pins on the side of the metal base, so if the bulb you are replacing pushed in and turned a quarter turn rather than screwing in, this is the one you want. It draws 7.3W and gives 806 lumens, and the pack puts that at a 60W replacement. The opal outer softens the light source, so you read a bright even glow rather than individual diodes through a thin shade.

At 4000K the light is a cool white: cleaner and a little bluer than the warm yellow of an old filament bulb, without going as stark as a 6500K daylight lamp. It suits kitchens, utility rooms, home offices, garages, landings and hallways, anywhere you want to see clearly and keep colours honest on a worktop or a page. In a sitting room or a bedroom it will read as brisk rather than cosy, so if you want lamp light to feel warm late in the evening, a 2700K version is the better choice.

It is dimmable, which many cool white LED bulbs are not. Use a dimmer switch rated for LED loads and check its minimum load, because an older mains dimmer built for filament bulbs can buzz or flicker with a lamp drawing only a few watts. The pack states a 15 year lifespan and carries energy rating E. Each box holds one bulb and this listing is sold in multiples of twelve, which makes it a practical way to re-lamp a whole house or keep spares on a shelf. Alongside it we stock B15 (SBC) candle and golf bulbs and a GU10 spot.

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

A B22 holder accepts a metal base with two small pins on its sides that you push in and twist a quarter turn to lock. Screw threaded holders are E27 and will not take this bulb.

Is 806 lumens as bright as the old 60W bulb I am replacing?

Yes. The pack rates it as a 60W replacement, and 806 lumens is the figure the old 60W filament bulbs produced, so the room should look much as it did before.

Will it work properly on a dimmer switch?

It is a dimmable lamp, so it will dim on a switch designed for LED loads. Older dimmers made for filament bulbs often have a minimum load too high for a 7.3W lamp and may hum or flicker.

What does 4000K cool white actually look like?

It is a clean, slightly crisp white, brighter in feel than 2700K warm white but well short of a blue toned 6500K daylight lamp. It keeps whites looking white on worktops and paintwork.

Is an IP rating given for this bulb?

No IP rating is stated by the manufacturer for this lamp, so none is quoted. The specification above lists only the figures the pack and the manufacturer actually state.

How many bulbs do I receive?

Each box contains a single bulb. The listing has a minimum order of twelve and is sold in multiples of twelve, so an order arrives as twelve individually boxed bulbs.
