E27 LED Candle Bulb 4.2W 470lm Dimmable - Cool White 4000K - LumiLife

This is a candle bulb with the larger E27 screw cap, the one often written as ES. It draws 4.2W and gives 470 lumens, which the retail pack rates as a 40W replacement, so it swaps straight in for an older incandescent candle without losing light. The colour is cool white at 4000K, neutral and clean rather than the yellow of a filament lamp, and the frosted body hides the LED chips so the glow stays even across the surface. The pack prints a 25,000 hour life and an instant start. One thing to flag: the specification gives 4.2W while the pack prints 5W, and the energy label shows 5kWh per 1,000 hours at class E.

An E27 candle is less common than the smaller E14 version, so check the cap on the old bulb before ordering. Where it does appear it is usually in chandeliers, multi-arm pendants, wall lights and table lamps whose shades were drawn around a slim, pointed bulb rather than a round one. The 280 degrees spread throws light almost all the way round, which suits an open fitting where the bulb is on show. Cool white at 4000K reads crisp rather than cosy, so it earns its place in kitchens, home offices, hallways and utility rooms.

It is dimmable, so it can sit on a dimmer circuit, though it wants an LED-rated dimmer rather than an old one built for filament lamps; a trailing edge model usually gives the smoothest low end. The rating is IP20, so keep it to dry indoor fittings. Each box holds one bulb, and this listing carries a minimum order of 10 in multiples of 10, which suits kitting out a whole chandelier. The same 4.2W candle is also made with a B15 (SBC) bayonet cap in warm white 2700K if that suits the fitting better.

Which light fittings take an E27 cap?

E27 is the larger of the two screw caps, sometimes written as ES, and the thread measures 27mm across. Unscrew the old bulb and compare it before ordering, because a good many candle fittings take the smaller E14 instead.

Will it dim properly?

Yes, it is dimmable. Pair it with an LED-rated dimmer, ideally a trailing edge type; older dimmers built for filament bulbs can flicker or buzz because the load on the circuit is now far lower.

How bright is 470 lumens in practice?

The pack rates it as a 40W replacement, so it matches an older incandescent candle bulb. In a five arm chandelier the total output is plenty for a dining table or a hallway.

What does 4000K cool white actually look like?

It reads as a clean neutral white with no yellow cast, closer to daylight than to candlelight. Good over worktops and desks; pick a 2700K warm white where you want a softer, more restful room.

Why does the wattage appear as both 4.2W and 5W?

The manufacturer specification gives 4.2W and the retail pack prints 5W, while the energy label shows 5kWh per 1,000 hours at class E. The light output is 470 lumens on every one of them.

How long should it last?

The pack prints a life of 25,000 hours. At three hours a night that works out at roughly twenty two years, and it reaches full brightness the moment you switch it on.
