B22 LED Candle Bulb 4.2W 470lm Non-Dimmable - Warm White

This is a 4.2W LED candle bulb from Energizer, fitted with a B22 bayonet cap, the push and twist base that most British ceiling roses and lamp holders take. It gives 470lm, which the retail pack rates as a replacement for a 40W incandescent candle, and it runs at 2700K, the warm white that reads soft and yellow rather than blue. The candle body is frosted white along its full length, so the light leaves diffused rather than as a hard point, and it spreads across a 240 degree beam.

Candle lamps go where the bulb is part of what you see: chandeliers, wall brackets, multi arm pendants and lantern fittings that leave the shape in open view. Check the cap before you order, because B22 bayonet and the smaller E14 screw cap are not interchangeable, and count how many lamps the fitting actually takes. Warm white at 2700K suits living rooms, hallways and bedrooms, where the light is meant to feel like the tungsten it stands in for rather than like daylight. This lamp is not dimmable, so it wants a standard on and off circuit rather than one wired to a dimmer.

The pack states a 15,000 hour lifespan, which it puts at 15 years in normal household use, and an energy class of E. At 4.2W the draw is a small fraction of the 40W lamp it stands in for, and that tells most in a fitting running five or six candles at once. A frosted finish shows dust more readily than a clear one, so give it an occasional wipe with a dry cloth once the lamp has cooled. One lamp comes to a box, and these are sold in multiples of twelve, which is a practical quantity if you are relamping a whole chandelier or keeping spares by.

Will this fit my existing lamp holder?

It fits a B22 bayonet holder, the two pin cap you push in and twist a quarter turn. It will not fit an E14 or E27 screw holder, so check the old lamp before ordering.

How bright is 470 lumens in practice?

The retail pack rates it as a 40W replacement, so it is the everyday candle brightness people know from chandeliers and wall lights rather than a high output lamp for task lighting.

Can I use it on a dimmer switch?

No. The supplier specification lists it as non dimmable, so it needs a plain on and off circuit. If your fitting is on a dimmer, choose a lamp marked dimmable instead.

What does 2700K warm white actually look like?

2700K is the warm, slightly yellow tone of traditional filament lighting. It flatters wood, brick and warm paint colours, and sits comfortably in living rooms and bedrooms in the evening.

Do I receive one bulb or a box of twelve?

One unit is a single lamp in its own box. These lamps are sold in multiples of twelve, so the smallest order is twelve individually boxed lamps rather than one box containing twelve.

Is the frosted finish different from a clear candle bulb?

Yes. A frosted body scatters the light so the diodes are not visible as bright points, which suits open fittings and shades where you look straight at the lamp.
