B22 (BC) LED GLS Bulb 13.8W 1521lm - Warm White 3000K, 6 Pack

This is a warm white LED GLS bulb on a B22 bayonet cap: the familiar rounded household bulb shape, drawing 13.8 watts and giving 1521 lumens at 3,000K. GLS is the shape most people picture when they think of a light bulb, and B22 is the push-and-turn bayonet cap, so it drops into the majority of British ceiling roses and lamp holders. The retail pack states a 100W equivalent, the brightness most people are matching when an older incandescent bulb goes. Six bulbs come in the sleeve, five plus one.

At 1521 lumens this is a main-light bulb rather than a mood one: a hall pendant, a kitchen ceiling fitting, a landing, or a tall floor lamp that has to light one end of a sitting room by itself. 3,000K sits a little above the yellow of an old filament bulb, so the light stays warm against wood, cream walls and painted cupboard doors without tipping into orange. The GLS shape is the wide general purpose one rather than a directional spot, which makes it a sensible choice under a fabric drum shade or a glass pendant where the bulb is partly on show.

The pack prints a bulb life of 15,000 hours, given as ten years, and more than 10,000 switching cycles, which is the number to look at for a stair or hall light flicked on and off all day. Dimming is not stated by the manufacturer, so we would run these from a plain on/off switch and keep a dimmer circuit for a bulb marked as suitable. One unit of this listing is the pack of six, and the minimum order is one, in multiples of one. For the same warm light on a smaller cap, our wider range includes 4.9W and 7.3W candle and golf bulbs on the B15 bayonet fitting, and a 7W E27 filament GLS in warm white 2700K.

Will a B22 cap fit my existing light fitting?

B22 is the bayonet cap, with two small pins on the side of the metal base. Push it in, twist a quarter turn and it locks. If the old bulb had a screw thread instead, you need an E27 cap rather than this one.

How bright is 13.8W next to an old bulb?

It gives 1521 lumens, and the retail pack states a 100W equivalent, so this is main ceiling light output rather than a bedside level of light.

What does warm white at 3,000K actually look like?

Warm and slightly creamy, close to an old filament bulb but a shade cleaner. It keeps wood, cream paint and brass looking warm, and it suits living rooms, halls and bedrooms.

Can I use this bulb on a dimmer switch?

The manufacturer does not state whether it can be dimmed, so we would not assume it. Run it from an ordinary on/off switch, or choose a bulb marked as dimmable where the circuit has a dimmer on it.

How many bulbs do I get, and how long should they last?

One unit of this listing is a pack of six bulbs, five plus one. The pack prints a bulb life of 15,000 hours, or ten years, and more than 10,000 switching cycles.

What supply does it need?

The pack states 220 to 240 volts at 50 to 60Hz, which is standard mains here, so it goes straight into a mains lamp holder with no driver or transformer to add.
