Endon 112119 dimmable B22 LED filament golf bulb, 4 W, 470 lm, 2700 K, clear

Endon 112119 is a clear LED filament bulb in the golf shape, a small round bulb 45 mm across and 75 mm tall. It has a B22 bayonet cap, and through the glass you can see glowing LED filaments arranged like the wire of an old incandescent lamp. The manufacturer intends it as a replacement for traditional bulbs in decorative light fittings.

Will it fit your lamp

B22 is a 22 mm bayonet cap: the bulb is pushed into the lampholder and turned rather than screwed in. It is the standard in the UK and Ireland, while most of continental Europe uses E27 and E14 screw caps, so check that your fitting has a B22 holder before ordering — the bulb will not go into an E27 or E14 socket.

Compare the 45 × 75 mm size with the inside of your shade. It is noticeably smaller than a standard pear-shaped A60 bulb, which is 60 mm across, so the golf shape fits where a pear-shaped bulb would be too large.

What light it gives

The bulb draws 4 W and gives 470 lm, roughly what an old 40 W incandescent bulb produced. That is light for a table lamp, a wall light or a multi-arm fitting rather than the only source in a large room. At 2700 K the light is warm and slightly yellowish, close to a traditional bulb.

The bulb is dimmable. You need a dimmer designed for LED lamps, and how smoothly and how low it dims depends on that dimmer's compatibility with the bulb. Clear glass does not diffuse the light, so the filaments stay visible and can glare at full brightness if the bulb sits at eye level without a shade. The manufacturer gives a 2-year warranty.
