E14 (SES) LED Golf Bulb 4.2W 470lm Dimmable - Warm White 2700K

This is a golf ball LED bulb on an E14 cap, the small Edison screw fitting that UK shops also label SES. It draws 4.2W and gives 470 lumens, and the pack sets that against a 40W filament bulb. The light is 2700K warm white, the mellow tone most people associate with the bulbs they grew up with rather than the whiter light of an office. The body is frosted white, so it reads as an even glow rather than a bright point, which matters on any fitting where the bulb sits in open view.

Golf ball bulbs are the small round type used where a full size GLS bulb would look heavy or would simply not fit: table lamps with narrow shades, wall lights, bedside fittings and small pendant clusters. Before ordering, check the cap on the bulb you are taking out. E14 is the narrower of the two common screw threads, while E27 is noticeably wider, and the two do not interchange. Warm white at 2700K sits well with cream walls, wood and brass, and it keeps a sitting room or bedroom restful in the evening rather than clinical.

It is dimmable, so it can sit on a dimmer circuit. Trailing edge dimmers made for LED loads give the smoothest result; an older dimmer built for filament bulbs often has a minimum load well above 4.2W, which shows up as flicker or a very short usable travel at the bottom of the dial. The energy rating is E, and the pack states a 15 year lifespan based on 15,000 hours. Each box holds one bulb, and the minimum order here is 12, sold in multiples of 12, which suits kitting out a whole house or holding spares. We also list LED candle bulbs on a B15 (SBC) cap at 4.2W and 7.3W.

Will this replace a 40W golf ball bulb in my lamp?

Yes, as long as the old bulb had the narrow E14 screw cap. At 470 lumens the pack puts it level with a 40W filament golf ball, on 4.2W.

Which dimmer switch should I pair it with?

A trailing edge dimmer designed for LED loads suits it best. Older dimmers made for filament bulbs often need a far higher minimum load than 4.2W and can cause flicker.

Is an IP rating given for this bulb?

No. The manufacturer states no IP rating, so treat it as an indoor lamp for ordinary dry fittings such as table lamps, wall lights and pendants.

How warm does 2700K actually look?

It is a soft yellow white, close to the old incandescent bulbs. It flatters wood, brass and cream paint, and reads much warmer than a 4000K or 6500K lamp.

How many bulbs do I receive?

Each box contains one bulb. The minimum order on this listing is 12 units, sold in multiples of 12, so a first order brings you twelve boxed bulbs.
