B22 (BC) LED Candle Bulb 4.2W 470lm Dimmable - Warm White 2700K

A candle bulb with a B22 bayonet cap, the push and twist fitting most UK shoppers know as BC. It draws 4.2W and gives 470lm, and the retail pack rates that as a 40W replacement, so it is a like for like swap for the old 40W candle bulbs in a chandelier or a shaded wall light. The finish is opal rather than clear, so the light leaves the lamp already softened instead of coming off a bright point. Colour temperature is 2700K, at the warm white end of the scale, and the lamp is dimmable. Energy rating is E.

Candle bulbs earn their keep wherever the lamp itself is part of what you see: multi arm chandeliers, wall brackets with small shades, and pendant clusters over a table. Because this one is opal, it works well where the bulb sits below eye level or peeks out from under a shade, since there is no filament coil to stare at. At 2700K the light reads yellow warm rather than white, which is what most people want in a living room, a bedroom or a hallway. 470lm from a single lamp is modest, which is why candle fittings usually carry three, five or six holders; count yours before you order.

Dimming depends on the dimmer as much as on the lamp: a switch built for filament loads may not hold 4.2W steady at the bottom of its travel, so check yours is rated for LED and that a multi lamp fitting clears its minimum load. The pack prints a 15 year lifespan, quoted as 15,000 hours. Each box holds one bulb, and the listing is sold in multiples of 12, so the smallest order is 12 boxes. If another cap or colour suits you better, we also list this 4.2W 470lm candle with a B15 (SBC) cap, a cool white 4000K version, and a brighter 7.3W 806lm candle.

How do I know my fitting takes a B22 cap?

Look at the old bulb. A B22 or BC cap has two small pins on a smooth metal base and pushes in with a quarter turn, rather than screwing in like an E27.

Will it dim properly on my existing dimmer switch?

The lamp is dimmable, but the switch decides how well it behaves. Use a dimmer rated for LED loads, and on a single lamp fitting check the dimmer's minimum load is 4.2W or lower.

Is 470lm bright enough to replace my old candle bulbs?

The pack rates 470lm as a 40W replacement, so it matches the common 40W candle bulb. Most chandeliers and wall lights take several lamps, which adds up quickly.

What does 2700K actually look like once it is on?

Warm and slightly yellow, close to the light an old filament bulb gave. It flatters wood, paint in warm tones and evening rooms rather than worktops and mirrors.

Does the manufacturer state an IP rating for this lamp?

No IP figure is printed on the pack or given in the specification, so we state none. Treat it as a lamp for ordinary indoor fittings in dry locations.

How many bulbs do I receive, and what is the smallest order?

One bulb per box. The listing is sold in multiples of 12 boxes, so the minimum order is 12 bulbs, which suits fitting out several multi lamp fixtures at once.
