B15 (SBC) LED Candle Bulb 4.9W 470lm - Warm White 3000K, 2 Pack

This is a candle bulb on the small bayonet cap, the B15 fitting UK trade sheets shorten to SBC. It is the 15mm bayonet with two side lugs, so it pushes in and turns a quarter rather than screwing: worth checking against your old bulb, because B22 looks similar but is the larger 22mm barrel and will not go in. The lamp draws 4.9W and gives 470 lumens, and the retail pack rates that as the equal of a 40W conventional candle. The body is plain opal white with a smooth taper to a rounded tip.

Candle lamps suit fittings that show the bulb: chandeliers, wall brackets, small pendants and shades that clip to the lamp rather than the holder. At 3,000K the light is a warm white, close to the yellowish tone of an older filament lamp, and it sits well with paint, wood and fabric in a sitting room, hall or bedroom. The 280 degree beam spreads light nearly all the way round the lamp instead of throwing it forward, which suits a multi-arm fitting where every bulb feeds one general glow. The opal finish diffuses the diodes, so a clear shade shows a lit surface rather than bright points.

The specification lists this lamp as non-dimmable, so give it a plain on/off switch; on a dimmer an LED not built for one can flicker, buzz or fail early. The pack prints a 10 year lamp life, and the energy label carries class F at 5kWh per 1,000 hours. It is rated IP20, for dry indoor fittings. One box holds two bulbs, which is useful when a pair of wall lights needs doing together, and the minimum order is 6 boxes, sold in multiples of 6. We list the same 4.9W B15 candle in cool white 4000K and daylight 6500K, and in a golf shape, if you are matching caps across a house.

How do I know whether my fitting takes a B15 cap?

Look at the bulb you are replacing. A B15 cap is a 15mm metal barrel with two small lugs on the side, and it pushes in then twists a quarter turn. The wider 22mm version is B22 and will not fit.

Can I use this bulb on a dimmer switch?

No. The specification lists it as non-dimmable, so wire it to an ordinary on/off switch. On a dimmer circuit an LED not designed for one can flicker, hum or fail well before its rated life.

How bright is 470 lumens in practice?

The pack rates it as the equal of a 40W conventional candle bulb. In a three or five arm chandelier the combined output is enough for a dining table or a decent sitting room.

What does warm white at 3,000K actually look like?

A soft yellow-toned white, warmer than daylight and close to old filament lighting. It suits evening rooms and keeps wood, cream paint and warm fabrics looking natural rather than washed out.

What supply voltage does it need?

It runs on standard UK mains at 220 to 240 volts, so no driver or transformer is required. It goes straight into an existing B15 lampholder with nothing else to add.

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

Each box holds two bulbs. The minimum order is 6 boxes, sold in multiples of 6, so the smallest purchase works out at 12 bulbs in total.
