E27 (ES) LED Golf Bulb 2.2W 250lm Non-Dimmable - Warm White 2700K

This is a golf ball LED bulb with an E27 Edison screw cap, the larger of the two screw fittings used on UK lamps and pendants. The opal finish diffuses the light so the LEDs inside are not visible as bright points through a clear shade. It draws 2.2W and gives 250 lumens at 2700K, a warm white close to the colour of an old filament lamp. The retail pack puts that output at the level of a 25W replacement, and prints an energy class of E.

A golf ball is shorter and rounder than a standard GLS bulb, which makes it the one to reach for when a shade sits low over the cap or a small fitting leaves little room above the holder. It suits bedside lamps, wall lights, small pendants and multi-arm fittings where several bulbs are on show at once, and the 180 degree beam spreads light across a broad hemisphere rather than throwing it in one direction. Being an IP20 bulb, it is for dry indoor positions only, so keep it to living rooms, bedrooms, hallways and landings.

There is no dimming here: the pack is marked non-dimmable, so wire it to a plain on and off switch. On a dimmer circuit an LED of this kind can flicker, buzz or fail early, and turning the dial down will not lower the output. The pack prints a 15 year lifespan and 15,000 hours of use, and the energy label rates the bulb at 3 kWh per 1,000 hours. Each box holds one bulb, and this listing has a minimum order of 12, sold in multiples of 12. It sits alongside our wider range of LED bulbs in golf and candle shapes, including B15 (SBC) versions in warm white and cool white.

Will this fit a standard screw lamp holder?

It has an E27 Edison screw cap, the larger screw size used on most UK table lamps and pendants. Check the old bulb for a threaded base roughly 27mm across rather than two push pins.

How bright is 250 lumens in a room?

The pack rates it as a 25W replacement, so treat it as a soft pool of light for a bedside lamp or a wall light rather than the main light for a large room.

Can I put it on a dimmer switch?

No. The pack marks it non-dimmable, so pair it with an ordinary on and off switch. On a dimmer it may flicker or buzz, and the output will not fall smoothly.

What does 2700K warm white actually look like?

It is a soft, slightly yellow light close to an old filament bulb, which flatters wood, warm paint colours and evening rooms rather than giving a crisp white.

Is a golf bulb smaller than a standard bulb?

Yes. The glass is a small round ball rather than the taller pear shape of a GLS, which helps where a shade or a fitting sits close above the holder.

How many bulbs do I get, and is there a minimum order?

Each box contains one bulb. This listing carries a minimum order of 12 units, sold in multiples of 12, so a first order brings twelve single boxes.
