E27 LED Candle Bulb 4.2W 470lm Dimmable - Warm White 2700K - LumiLife

This is a candle shaped LED bulb with an E27 screw cap, drawing 4.2W and giving 470 lumens. The pack rates it as a 40W replacement, so it is a straight swap for an older incandescent candle lamp without losing light. The colour temperature is 2700K warm white, the softer yellow end of the white range, and the frosted outer surface spreads the light rather than letting the individual diodes read as bright points. It is dimmable, which is worth knowing before you buy.

The candle shape earns its keep where the bulb is on show: chandeliers, multi arm ceiling fittings, wall lights with open shades and small table lamps. E27 is the larger of the two common screw caps, so check the old bulb first, because many candle fittings take the smaller E14 instead. The quoted beam angle is 280 degrees, wide for a candle, which means light travels sideways and back up towards the ceiling as well as forwards. In a dining room or hallway that keeps a fitting looking evenly lit rather than bright only underneath. It carries an IP20 rating, so it suits dry indoor positions.

Dimming is where a little care pays off: as with any LED lamp, the dimmer needs to be one rated for LED loads, and an older dimmer sized for filament bulbs may hum or refuse to run so small a wattage. The energy label puts the lamp in class E, at 5kWh per 1000 hours of use, and the manufacturer does not state a rated lifespan. Each unit is a single bulb, with a minimum order of 10 in multiples of 10, which suits fitting out a multi arm light in one go and keeping spares. The same lamp is also listed with a B15 bayonet cap.

How do I know whether my fitting takes E27 or E14?

Take the old bulb out and measure the screw thread across its widest point. E27 measures about 27mm and E14 about 14mm, and candle fittings are sold in both, so the shape alone will not tell you.

Is 4.2W really as bright as the 40W candle bulb it replaces?

The pack rates it as a 40W replacement and the output is 470 lumens, which is the figure to compare rather than the watts. Watts describe how much power the lamp draws, not how much light comes out.

Will it work on my dimmer switch?

The lamp itself is dimmable. The switch needs to be rated for LED loads, because older dimmers designed for filament bulbs often have a minimum load far above 4.2W and may buzz or flicker.

What does warm white 2700K look like in a room?

It is the warm, slightly yellow light people associate with old filament bulbs, rather than the crisp blue white of daylight lamps. It flatters wood, warm paint colours and skin tones in the evening.

Do the individual LEDs show through the frosted finish?

The outer surface is frosted rather than clear, and a frosted surface diffuses light, so the lamp reads as one soft glow instead of a cluster of bright points in an open shade.
