E27 (ES) LED Filament Candle Bulb 2.2W 470lm - Warm White 2700K

This is a candle bulb with an E27 screw cap, the larger of the two common screw sizes in UK homes, and it draws 2.2W to give 470 lumens. Inside the clear glass sit four straight LED filament strips, so it carries the look of a wound filament lamp while using a fraction of the power. The retail pack rates it as a 40W replacement and the printed energy class is A. At 2700K the light is warm white, the yellow leaning tone people associate with a traditional incandescent bulb rather than the flatter light of a 4000K lamp.

An E27 cap is the first thing to check on chandeliers, wall brackets and small pendants, since many candle fittings take the smaller E14 instead. Because the filaments are the part you look at, this bulb suits fittings that leave the glass on show: open chandelier arms, clear glass shades, caged pendants and lantern style wall lights. In a shade that hides the bulb completely you gain nothing from the filament styling. At 470 lumens the output is moderate rather than bright, so it reads best in multiples across a five arm chandelier, or as a single soft light in a hallway or over a dining table.

The pack marks the bulb non-dimmable, so give it a plain on and off switch; on a dimmer circuit an LED filament lamp can flicker, buzz or fail early. The pack also prints a 50 year lifespan, and the energy label gives consumption of 3kWh per 1000 hours, which is what the A class reflects. One unit is a single bulb, and the minimum order is 12 units, sold in multiples of 12, so it suits fitting out a whole chandelier and keeping spares aside. Before ordering, unscrew the old bulb and measure the thread: an E27 is about 27mm across.

Will this replace a 40W candle bulb in an existing fitting?

Yes, provided the holder is an E27 screw cap. The pack rates the 470 lumen output as a 40W replacement, so the brightness should feel familiar.

How do I tell an E27 cap from an E14?

Measure the threaded metal cap on the old bulb. An E27 is roughly 27mm across and an E14 roughly 14mm, so the difference is obvious once measured.

Can I put it on a dimmer switch?

No. The pack marks this bulb non-dimmable, so use a standard on and off switch. On a dimmer it may flicker, hum or fail early.

What does 2700K warm white actually look like?

It is a soft yellow toned light, close to old incandescent bulbs, and it flatters wood, brick and warm paint far more than a cooler 4000K lamp.

Is a moisture protection rating given for this bulb?

The manufacturer does not state an IP rating for this lamp, so there is no protection figure to quote. It is an ordinary indoor bulb for enclosed or open fittings.
