B22 LED Candle Bulb 4.9W 470lm - Warm White 3000K, 2 Pack - Energizer

This candle bulb takes a B22 bayonet cap, the push and twist fitting most UK shoppers call BC, and it is an LED replacement for the small tapered lamps used in chandeliers, wall lights and table lamps. It draws 4.9W and gives 470 lumens at 3,000K, a warm white close to the colour of an old incandescent lamp rather than the blue white of an office tube. The body is opal white rather than clear, so the light leaves it softened instead of as a bright point, which matters when the tip of the lamp sits on show below a shade.

Candle lamps do most of their work in multi arm ceiling fittings and in pairs of wall lights, where five or six bulbs at 470 lumens each build the light in a room between them rather than one bulb carrying the whole ceiling. At 4.9W apiece, a five arm chandelier fitted with these draws under 25W in total. The beam spreads across 280 degrees, close to the all round throw of the filament lamps these stand in for, so an upward facing wall bracket still washes the wall and ceiling instead of dropping a tight pool on the floor.

This lamp is non-dimmable, so wire it to a plain on and off switch. On an existing dimmer it may flicker, buzz or fail to strike, and a dimmer sized for filament lamps rarely sees enough load from a few watts of LED, so change the switch or choose a lamp that states it is dimmable. The energy label coded to this bulb reads class F at 5 kWh per 1,000 hours, and the IP20 rating puts it in dry indoor positions. Each box holds two bulbs and the order minimum is six boxes, twelve bulbs in all. We also stock Energizer candle bulbs with the smaller B15 (SBC) cap, in warm white and cool white.

How do I check my fitting takes a B22 (BC) cap?

Look at the base of the bulb you are replacing. A B22 has two small pins on a plain metal cylinder and pushes in with a quarter turn, rather than screwing in like an E27.

Which old bulb does 470 lumens stand in for?

The manufacturer states no equivalent wattage for this lamp, so work from lumens instead. Check the lumen figure printed on the bulb you are replacing and match it to 470 lumens.

Will it work on a dimmer switch?

No. The specification records it as non-dimmable, so fit it to a standard on and off switch. On a dimmer it may flicker, buzz or fail to light at all.

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

It is a soft yellow-toned white, close to an old filament lamp and a little warmer than the neutral 4,000K white often chosen for kitchens and workshops.

How wide is the light spread?

The beam covers 280 degrees, so light leaves almost the whole bulb rather than one face. That suits chandeliers and wall brackets where the lamp points up or sideways.

How many bulbs come in a box, and what is the least I can order?

Each box contains two bulbs, and the minimum order is six boxes sold in multiples of six, so twelve bulbs arrive in the smallest order.
