E27 (ES) LED GLS Bulb 5W 470lm Dimmable - Warm White 2700K

This is a 5W LED GLS bulb with an E27 screw cap: the classic rounded household bulb shape, with a frosted finish that softens the light before it leaves the bulb. It gives 470 lumens at 2700K, a warm white close to the colour old incandescent bulbs gave, and the beam angle is 240 degrees, so light spreads sideways and upwards rather than being thrown forwards in a cone. It is dimmable, and LumiLife prints a 42W replacement figure on the retail pack.

E27, often written ES for Edison Screw, is the larger of the two common screw caps in the UK, and it turns up in table lamps, floor lamps, pendants, wall lights and most shaded fittings sold here. Before ordering, check the bulb you are replacing: a threaded screw roughly 27mm across is E27, a narrower screw thread is E14, and two push and twist pins mean a bayonet cap, which will not fit. The frosted finish and the wide spread suit a fabric or paper shade, where a clear bulb can throw harder shadows onto the material. At 470 lumens this is a bedside lamp, side lamp or hallway pendant bulb rather than the only light in a big room.

Dimming is the reason to pick this over a fixed output bulb, and it wants a dimmer built for LED loads; older mains dimmers were designed for far heavier filament loads and a single 5W lamp may sit below their minimum. The energy label rates it class F at 5 kWh per 1000 hours. It is IP20, so dry indoor fittings only. One unit is a single bulb, and the minimum order is 10, sold in multiples of 10, which covers a whole house in one go with spares left over. We also stock a dimmable B15 candle bulb at the same 470 lumens and 2700K warm white.

Which fittings take an E27 bulb?

E27 is the larger screw cap, also written ES for Edison Screw. Check the bulb you are removing for a threaded screw base around 27mm across; a narrower thread is E14 and push and twist pins are a bayonet cap.

Will it work with my dimmer switch?

The specification states that it is dimmable. Use a dimmer made for LED loads, because older filament dimmers often have a minimum load that a single 5W lamp cannot reach, which usually shows up as flicker.

How bright is 470 lumens in practice?

It is a soft, lamp level output. The pack prints a 42W replacement figure, so expect the light of a small old style bulb: right for a bedside or side lamp, not for lighting a whole room alone.

What does 2700K warm white actually look like?

2700K sits at the yellow toned end of white light, close to old filament bulbs. It flatters wood, warm paint colours and skin tones, and it suits living rooms and bedrooms in the evening.

What does a 240 degree beam angle mean for a shade?

Light leaves almost the whole bulb rather than one face, so it fills a shade evenly and throws upward as well as down. There is no tight spot or hard edge to the pool of light.

What does the F energy rating tell me?

The label scale runs from A to G and rates efficiency, not brightness. This lamp is class F, and the label gives its consumption as 5 kWh per 1000 hours of use.
