B22 (BC) LED Filament Golf Bulb 2.2W 250lm - Warm White 2700K

This is a golf ball sized LED lamp with a B22 bayonet cap, the standard push-and-twist cap used on most British light fittings. It draws 2.2W and gives 250 lumens at 2700K, a warm white close to the light an old filament bulb produced. Inside the clear glass sit two slim LED filament strips, so the lamp reads as a traditional bulb rather than a modern one when it is on show. The pack puts it at a 25W replacement, and the energy label carries class E with a figure of 3kWh per 1,000 hours.

Golf bulbs are the small round ones, narrower than a standard GLS, which is what makes them useful where a shade is tight or a fitting is shallow: small table lamps, bedside lamps, wall lights, multi-arm pendants and chandeliers with bayonet lampholders. Because the glass is clear the filaments are visible when lit, so it suits open shades, glass shades and anything where the bulb itself is part of the look. Behind a solid fabric shade the clear glass makes no odds, and you still get the same 250 lumens.

This lamp is not dimmable, so put it on an ordinary switch rather than a dimmer circuit; run on a dimmer, a non-dimmable LED tends to flicker or buzz. The pack prints a 15,000 hour life and an instant start, which means full brightness the moment the switch goes on, with no warm-up period. The 250 lumen figure is quoted in a sphere, that is total output in every direction rather than down a beam, which is what you want from a lamp sitting in a shade. Each box holds one bulb, and the minimum order is 10, sold in multiples of 10. A B15 candle bulb in the same warm white 2700K sits alongside it if you have smaller bayonet fittings elsewhere.

Which lampholders take a B22 cap?

B22 is the bayonet cap, the one with two side pins that you push in and turn a quarter turn to lock. If your old bulb screwed in, it is an E27 or E14 and this one will not fit.

What will 250 lumens and a 25W replacement rating cover?

The pack rates it as a 25W replacement, so it suits shaded table lamps, bedside lights and multi-arm fittings where several bulbs share the work rather than lighting a whole room on its own.

Can I put it on a dimmer switch?

No. This lamp is not dimmable, so wire it to an ordinary switch. Non-dimmable LEDs on a dimmer circuit commonly flicker, hum or fail early, whatever the dimmer is set to.

What sort of light does 2700K give?

2700K is a warm white with a yellow cast, close to the old incandescent bulbs, and the clear glass leaves the two filament strips on show, which is worth thinking about in an open shade at eye level.

Does the manufacturer give an IP rating?

No IP rating is printed on the pack or given by the manufacturer for this lamp. If a fitting calls for a lamp with a stated rating, check that fitting's own instructions first.

How many bulbs do I receive?

Each box contains a single bulb. The minimum order on this listing is 10 boxes, sold in multiples of 10, so ten bulbs is the smallest quantity available.
