Description
A golf bulb is the small round lamp that sits between a candle and a full-size GLS, and this JCB one draws 3W of LED to give 250 lumens. The cap is E14, the narrow screw thread UK trade lists also call SES, so check that the lamp you are replacing has a slim screw base rather than a wider E27 thread or a push-and-twist bayonet. The finish is plain opal white, and the pack gives the bulb as 45mm across and 80mm tall. Light spreads over 180 degrees, a broad wash rather than a directed beam.
At 250 lumens the output is gentle, equal to the 25W filament lamp the pack says it replaces. That suits fittings where several lamps share the work, such as a multi-arm chandelier or a pendant cluster, and places wanting presence rather than brightness: a bedside lamp, a hall pendant, a wall light, the small shades on a dining fitting. The short round body sits inside a narrow shade where a longer lamp would push past the rim. It sits alongside our wider range of JCB LED golf and candle bulbs in E14, B15 and B22 caps, in warm white, cool white and daylight.
At 3,000K the light reads warm white, nearer the yellow of an old filament lamp than the whiter 4,000K and 6,500K options, so it flatters wood and warm paint. Both the specification and the pack state the lamp is not dimmable, so give it a plain on/off switch and keep it off dimmer circuits. The pack prints a 10,000 hour life, up to ten years of use, instant full brightness and an 88% energy saving against the lamp it replaces, while the energy label rates it class G at 3kWh per 1,000 hours. One unit is a single bulb; the minimum order is 12, sold in multiples of 12.

Frequently Asked
How do I tell whether my fitting takes this cap?
Look at the base of the old bulb. An E14 cap is a screw thread about 14mm across, noticeably slimmer than the common E27 thread, and it twists in rather than pushing and turning like a bayonet cap.
How bright is 250 lumens in a real room?
It matches the 25W filament lamp the pack names as its equivalent, so treat it as soft rather than main light. In a multi-arm fitting several of them together give a comfortable overall level.
Can I put it on a dimmer switch?
No. The specification and the pack both give it as non-dimmable, so wire it to an ordinary on/off switch and choose a dimmable lamp if you need the level to vary.
What does the 180 degree beam angle mean for shades?
Light leaves the dome across a wide arc instead of a narrow cone, so it fills a shade evenly and works pointing up, down or sideways without leaving a dark ring.
What light colour will I get, and how long is it rated for?
3,000K warm white, a soft yellow-toned light. The pack prints a 10,000 hour life and up to ten years of use, with full brightness the moment you switch it on.
