Description
This is a golf ball bulb: the small round shape that sits neatly in a shade, with an opal finish that softens the light rather than letting the diodes show through the glass. It takes a B22 bayonet cap, the two-pin push-and-twist fitting most British ceiling roses and lamp holders use, so check the old bulb for two small pins rather than a screw thread before you order. The LED draws 4.9W for 470 lumens at 3,000K warm white, and the pack puts that at the equivalent of a 40W conventional bulb.
A golf bulb earns its place wherever a full-size GLS bulb looks clumsy: small pendant shades, multi-arm ceiling fittings, wall lights, bedside lamps and glass shades that leave the bulb half on show. The 240 degree beam spreads light almost the whole way round the lamp rather than throwing it forward, so a shade fills evenly and an exposed bulb leaves no dark patch above it. At 470 lumens one of these is right for a bedside table or a hallway, while three or four together in a multi-arm fitting will light a whole room.
The specification lists this lamp as non-dimmable, so give it a plain on/off switch; a dimmer circuit needs a lamp rated for one. The energy label rates it F and measures 5kWh per 1,000 hours. The pack states a 10 year lamp life. IP20 covers dry indoor positions only. Each box holds two bulbs and the minimum order is six boxes in multiples of six, which is twelve bulbs, useful when you are relamping a fitting with several heads at once. It sits alongside our wider range of Eveready LED golf and candle bulbs in warm white, cool white and daylight.

Frequently Asked
Will this fit my existing bayonet lamp holder?
Yes, if the old bulb has two small pins on the side of a metal cap rather than a screw thread. B22 is the full-size bayonet: push it in and twist a quarter turn to lock.
How bright is 470 lumens in practice?
The pack rates it as the equivalent of a 40W conventional bulb, so it suits a bedside lamp, a wall light or one head of a multi-arm fitting rather than lighting a large room alone.
Can I use it on a dimmer switch?
No. The specification lists the lamp as non-dimmable, so it needs a plain on/off switch. Running a non-dimmable LED on a dimmer can cause flicker, buzzing and a shortened life.
What does 3,000K warm white actually look like?
It is a soft, slightly yellow white, close to the tone people remember from older household bulbs. It flatters wood, warm paint colours and skin tones in living rooms and bedrooms.
What voltage does it run on?
It works on a 220 to 240V supply, which is standard UK mains, so it needs no driver, transformer or separate control gear of any kind.
How many bulbs do I actually receive?
Each box holds two bulbs, and the minimum order is six boxes in multiples of six, so the smallest order brings you twelve bulbs in total.
