Energizer LED GLS Bulb B22 18W Opal Non-Dimmable - Daylight 6500K

This is a bayonet cap LED bulb in the familiar GLS shape, the rounded pear form that has been the standard household bulb for decades. It draws 18W and gives 2452 lumens, which the pack puts against a 150W filament bulb. That output puts it at the bright end of household bulbs, so it is the one to reach for where a single ceiling pendant has to light a whole room. The light is 6500K daylight, the coolest and crispest of the white tones, with a clear blue-white cast rather than any yellow.

B22 is the push and twist bayonet fitting found in many British ceiling roses and table lamps. If the bulb you are replacing has two small pins on the side of a smooth metal cap rather than a screw thread, this will fit. Daylight at 6500K suits places where you want to see clearly and accurately: a garage, a workshop, a utility room, a home office desk lamp or a kitchen worktop pendant. It is less at home in a bedroom or a sitting room, where most people prefer a warmer tone. Check that your shade has room for the full length of a GLS bulb.

There is no dimming: the pack marks it non-dimmable, so keep it off dimmer circuits, where a non-dimmable LED can flicker or buzz. The pack prints a 15 year lifespan, and the energy rating is D. Each box holds one bulb, and the minimum order is 12, sold in multiples of 12, which suits fitting out a whole house or keeping spares for a rental. It sits alongside our wider range of LED bulbs, including B15 candle and golf shapes and GU10 lamps. Fit it with the power off, and hold the body rather than the glass when you push and twist.

Will this fit my existing light fitting?

It takes a B22 bayonet cap, the push and twist fitting with two pins on the side. If your old bulb has a screw thread instead, it will not fit.

How bright is 2452 lumens in practice?

Brighter than most household bulbs. It is a sensible choice for a single central pendant lighting a full room, a garage or a workshop bench.

Can I use it with a dimmer switch?

No. The pack marks it non dimmable, so wire it to a plain on and off switch. A non dimmable LED on a dimmer can flicker, buzz or fail early.

What does 6500K daylight look like next to warm white?

It reads as a crisp blue white rather than the yellow glow of a 2700K bulb, which makes colours and detail easier to judge when working.

Is an IP rating given for this bulb?

The manufacturer does not state one, so treat it as a lamp for ordinary dry indoor fittings only and check any fitting of your own for its own rating.

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

Each box contains one bulb. The minimum order for this listing is 12 units, sold in multiples of 12, so you receive 12 single boxes.
