B15 LED Filament Candle Bulb 4W 470lm - Warm White 2700K - Energizer

This is an LED candle bulb on a B15 cap, the small bayonet fitting usually written as SBC, with clear glass and slim filament strips running the length of the body. It draws 4W and gives 470 lumens at 2700K, a warm white, and the pack rates it as a 40W replacement. The filaments sit in line rather than behind a diffuser, so light spreads around the bulb instead of firing forward, and the lamp carries an energy rating of E.

Candle bulbs on a small bayonet cap turn up most often in chandeliers, candelabra-style ceiling lights, wall lights and mantel lamps, where several low-output bulbs share the work rather than one bright one. Clear glass and exposed filaments mean the bulb itself is part of the look, so it suits open shades, glass hurricanes and fittings that leave the lamp on show; behind a fabric shade the filament detail is wasted, though the light is the same. At 2700K the light is the yellow-toned warm white most people associate with older household bulbs, which sits comfortably in living rooms, dining rooms and hallways.

Check the dimming before you buy: this bulb is not dimmable, so it needs a plain on-off switch, and fitting it to a dimmer circuit risks flicker or an early failure. The pack prints a 15 year lifespan and 15,000 hours of use, which is reckoned on typical household hours rather than continuous running. Each box holds one bulb, and the minimum order is 12, sold in multiples of 12, which suits a whole chandelier or a set of wall lights at once. We also list B15 candle bulbs in dimmable versions at 470lm and 806lm, and in cool white 4000K.

What is a B15 cap and will my fitting take one?

B15 is the small bayonet cap: two pins on a 15mm base that pushes in and twists a quarter turn. Measure the old bulb rather than the fitting, because B22 looks similar but is noticeably wider.

Can I put this on a dimmer switch?

No. The specification states it is not dimmable, so it needs an ordinary on-off switch. On a dimmer circuit you risk flicker, buzzing or an early failure.

How bright is 470 lumens in practice?

470 lumens is the output the pack equates to an old 40W filament candle, which is enough for a multi-arm chandelier or a pair of wall lights working together.

What does 2700K warm white actually look like?

2700K is a yellow-toned warm white, close to old incandescent lighting. It flatters warm paint, wood and brass tones, and stays easy on the eye in the evening.

Does the manufacturer state an IP rating?

No IP rating is printed on the pack or listed in the specification, so none is quoted here. Treat it as a standard unrated lamp for ordinary indoor fittings.
