B15 (SBC) LED Candle Bulb 4.2W 470lm Dimmable - Cool White 4000K

This candle bulb takes a B15 small bayonet cap, the narrower of the two push and twist bayonet fittings and the one commonly found on chandeliers, wall lights and smaller shades. It draws 4.2 watts and gives 470 lumens, and the retail pack sets that against a 40 watt replacement, so it is a straight swap for an old incandescent candle. The finish is opal rather than clear, so the light reads as one even sheet rather than a row of bright points, and nothing inside shows through when the lamp is lit.

Cool white at 4000K is cleaner and more neutral than the 2700K warm white most homes default to, and it suits rooms where you want to see clearly: a kitchen pendant, a hallway or landing fitting, wall lights over a worktop, a desk or dressing table lamp. It keeps chrome, nickel and white paint looking true rather than yellowed. Fit the same colour temperature across a whole circuit, because one 4000K bulb beside a 2700K one shows up straight away. We also list this candle in warm white 2700K, a brighter 7.3W 806lm candle, and B15 golf bulbs at the same 4.2W and 470lm.

The pack marks the bulb as dimmable. Pair it with a trailing edge dimmer rated for LED loads and check the dimmer's minimum wattage, since 4.2 watts is a very small load and an old filament dimmer will often flicker or drop out near the bottom of its travel. The pack also prints a 15 year lifespan and an energy class of E. Each box holds one bulb, and the listing is sold in multiples of twelve, which covers a full chandelier with spares left over. No IP rating or beam angle is stated by the manufacturer.

How do I know if my fitting is B15 and not B22?

Both are push and twist bayonet caps with two side pins, but B15 measures 15mm across the metal cap and B22 measures 22mm. Take the old bulb out and compare it before ordering.

Will it dim properly on my existing dimmer switch?

The pack marks the bulb as dimmable. It performs best on a trailing edge dimmer made for LED loads; older dimmers built for filament bulbs can flicker or cut out because 4.2 watts is a very small load for them.

Is 470 lumens as bright as the 40 watt candle I am replacing?

The pack states a 40 watt replacement, so it is intended as a like for like swap in light output. In an opal candle the light spreads evenly rather than concentrating into a filament point.

What does 4000K cool white actually look like?

It is a neutral white with no yellow cast, closer to daylight than to a traditional filament bulb. Warm white at 2700K looks noticeably more golden beside it, so keep one temperature per room.

Does the manufacturer state an IP rating?

No. Neither the specification nor the retail pack prints an IP rating, so we quote none. Treat it as a lamp for ordinary dry indoor light fittings and enclosures.

How many bulbs do I receive?

One bulb per box. The listing has a minimum order of twelve, sold in multiples of twelve, so the smallest purchase is twelve individual bulbs.
