B22 LED Filament Candle Bulb 5W 550lm Dimmable - Cool White 4000K

This is a 5W LED filament candle bulb with a B22 bayonet cap, the standard push-and-twist fitting on most British ceiling roses and wall lights. The glass is clear and the filament strips run the full height of the body, so the bulb is meant to be seen rather than hidden inside a shade. It draws 5W and gives 550 lumens, which the pack quotes as 550 lumens in a sphere, and the pack rates it as a 40W replacement. The colour temperature is 4000K cool white, a clean white without the yellow most clear filament lamps give, so check it against any warmer bulbs already in the same fitting.

Cool white at this brightness suits places where you want the room to read as bright and awake: a kitchen with candle lamps in a ceiling fitting, a landing, a home office, a utility room, a hallway pendant that has to work first thing in the morning. Because the glass is clear, the filaments throw small bright points of light across nearby surfaces, which looks good in an open fitting, a lantern or a shade-free chandelier and can be glary at eye level.

The lamp is dimmable, which is unusual enough among filament candles to be worth planning around: pair it with a dimmer rated for LED loads, and check the dimmer's minimum load, because a single 5W lamp on a switch built for 40W and upwards can flicker or refuse to strike. The energy rating is E and the pack prints a 15-year lifespan. Each unit is one bulb, and the minimum order is 12, sold in multiples of 12, so it suits fitting out a whole chandelier or keeping spares on the shelf. We also list LED candle bulbs on the smaller B15 (SBC) cap in cool white 4000K and warm white 2700K.

Will this fit my existing lampholder?

It takes a B22 bayonet holder, the two-pin cap you push in and twist a quarter turn. If the old bulb has a screw thread instead, that is an E14 or E27 lamp and this one will not fit.

How different is 4000K cool white from a normal warm bulb?

Noticeably crisper. Most household candle bulbs run at 2700K, which looks yellow beside this. Mixing the two in one chandelier is obvious, so change the whole fitting over at once.

Can I run it on a dimmer switch?

Yes, the specification confirms it is dimmable. Use a trailing edge dimmer rated for LED loads and check its minimum wattage, since 5W alone may fall below what an older dimmer needs.

Does the manufacturer give an IP rating?

No IP figure is printed on the pack or given in the specification, so we state none. Treat it as a lamp for ordinary dry indoor fittings in the usual way.

How many bulbs do I receive, and is there a minimum?

One bulb per unit. The minimum order is 12 units, sold in multiples of 12, which covers a full multi-arm fitting with a few spares left over.

Is 550 lumens enough to replace a 40W candle bulb?

The pack rates it as a 40W replacement at 550 lumens, so output is comparable while the draw drops to 5W on each lamp in the fitting.
