E27 (ES) LED Candle Bulb 4.9W 470lm - Warm White 2700K, 2 Pack

This is a candle bulb with an E27 screw cap, which is the larger of the two screw fittings you will meet on a British light fitting. It draws 4.9W and gives 470 lumens of warm white light at 2700K, and the pack rates that against a 40W filament candle bulb. The body is plain white rather than clear, so the light comes out diffused rather than picked out as a bright point. The pack prints the bulb at 98mm long and 35mm across the glass, and they come two to a box.

E27 candle bulbs are less common than the E14 sort, and they turn up in older chandeliers, wall brackets and pendant fittings built around a full size screw lampholder. Before ordering, look at the cap on the bulb you are taking out: E27 measures 27mm across the screw thread and E14 measures 14mm, and the difference is plain once you hold the two together. Because a candle shape is tall and narrow, it also suits small shades and half shades where a rounder bulb would press against the fabric, and it looks tidy in a fitting that leaves the lamp on show.

The pack marks the bulb as non dimmable, so pair it with an ordinary on and off switch; on a dimmer circuit an LED not built for dimming can flicker, buzz or refuse to strike. Warm white at 2700K sits at the softer end of the scale, close to the yellow light of an old incandescent bulb, which makes it easy to live with in a sitting room or a hallway. The energy rating is F, and the pack claims up to 90% less energy than the bulb it replaces along with a life of up to 15 years. They arrive two to a box, which suits a pair of matching wall lights.

How do I tell whether my fitting takes E27 or the smaller E14?

Look at the cap on the old bulb. E27 is 27mm across the screw thread and E14 is 14mm, so the larger one is unmistakable once you compare them.

Can I put this on a dimmer switch?

No. The pack marks it non dimmable, and on a dimmer an LED built for switching only may flicker, hum or fail to light at all.

How bright is 470 lumens in practice?

The pack puts it level with a 40W filament candle bulb, so it is a soft everyday level that works well in fittings holding three or more lamps.

What does warm white 2700K look like?

It is a yellow toned light much like the old incandescent bulbs, kind to skin tones and comfortable in living rooms, bedrooms and hallways in the evening.

Will it fit inside a small shade or a glass sleeve?

The pack gives 98mm length and 35mm diameter, so measure the clearance inside your shade or sleeve before ordering and allow a little room around the glass.

Does the pack give a protection rating?

The manufacturer does not state an IP figure, so there is no water or dust protection to work from; keep it to ordinary dry indoor fittings.
