Description
This is the standard household bulb shape, a GLS, in LED form with an E27 screw cap. It draws 4.9W and puts out 470 lumens at 3000K, which the pack gives as the replacement for an old 40W incandescent. The body is white rather than clear, and the light leaves it over a 180 degree spread, so it fills a shade evenly instead of throwing a narrow beam. JCB prints a 10,000 hour life on the box and rates it at up to 10 years.
E27 is the larger of the two screw caps in common UK use, and the 27 is the thread diameter in millimetres. It is what most pendant fittings, standard table lamps and floor lamps take. If the bulb you are replacing has two pins on the side of its cap, that is a bayonet fitting and this one will not go in. At 470 lumens the output is gentle rather than fierce, which suits a bedside lamp, a hall pendant, a landing fitting, or a pair of lamps sharing the work in a sitting room. The 3000K warm white keeps creams, woods and warm paint colours looking warm rather than clinical.
There is no dimming here: the specification gives it as non-dimmable, so put it on a plain on/off switch. Run on an existing dimmer it may flicker, buzz, or refuse to light at the bottom of the dial. The IP20 rating means no protection against water, so keep it to indoor fittings in dry rooms. The energy label puts it in class F, measured at 5kWh per 1000 hours. One listing is one bulb, ordered in multiples of twelve, and it sits alongside the same 470lm output in bayonet cap, candle and golf ball shapes, and in cool white 4000K and daylight 6500K where a crisper light suits the room better.

Frequently Asked
Which light fittings will this screw into?
Any fitting that takes an E27 screw cap, the larger of the two UK screw sizes, which covers most pendants, standard table lamps and floor lamps.
Will it look as bright as the 40W bulb I am taking out?
Yes. The pack gives it as a 40W replacement, and 470 lumens is the output an old 40W household bulb produced, using 4.9W to do it.
Can I put it on a dimmer switch?
No. The specification gives this lamp as non-dimmable, so it needs a plain on/off switch. On a dimmer it may flicker, buzz or fail to light.
What does 3000K warm white actually look like?
A soft, slightly yellow white, close to the tone of an old filament bulb. It flatters creams, woods and warm paint, and suits evening rooms.
Is it suitable for an outside light?
No. IP20 means the lamp has no protection against water or damp, so keep it to indoor fittings in dry rooms only.
Does it come on at full brightness straight away?
Yes. LED lamps reach their full output the moment the switch is thrown, with none of the warm up delay older energy saving bulbs had.
