Energizer LED GLS Bulb B22 (BC) 12.6W Opal Dimmable - Daylight 6500K

This is a 12.6W LED GLS bulb on a B22 bayonet cap, the classic push and twist fitting still found on most older British pendants and table lamps. GLS is the familiar rounded household bulb shape, so it sits in a shade the same way the filament bulb it replaces did. It gives 1521 lumens at 6500K, which the pack calls daylight, and the pack rates it as a replacement for a 100W filament bulb. The bulb itself is finished in a soft white rather than clear, so the light spreads evenly instead of showing a bright point of filament.

6500K is at the cool end of white light, closer to overcast daylight than to the yellow of an old filament bulb, and it reads as crisp and slightly blue beside a 2700K lamp. That makes it a working light rather than a relaxing one: kitchens, utility rooms, garages, workshops, home offices and hallways where seeing clearly matters more than atmosphere. At 1521 lumens it is one of the brighter household bulbs, so one on a central pendant is usually enough for a small room. Mixing it with warm white bulbs in the same room is best avoided, as the difference in tone is obvious.

The bulb is dimmable, so it can go on a circuit with a dimmer switch, though older dimmers built for filament bulbs often will not run LEDs smoothly; a trailing edge LED dimmer gives the steadiest result. The energy rating is E, and the pack prints a 15 year lifespan, quoted as 15,000 hours. Each box holds one bulb, and the minimum order is 12, sold in multiples of 12, which suits changing a run of fittings at once or keeping spares by. It sits alongside our wider range of LED bulbs in candle, golf, spot and tube types.

Will this fit an old bayonet cap light fitting?

Yes. B22 is the standard bayonet cap with two side pins that pushes in and twists a quarter turn. Check the old bulb has two pins on a smooth cap rather than a screw thread.

How bright is 1521 lumens in practice?

The pack rates it as a 100W filament replacement, so it is a bright general purpose bulb. On a central pendant one is normally enough to light a small or medium room.

What does 6500K daylight actually look like?

It is a crisp white with no yellow in it, close to overcast daylight. Beside a 2700K warm white lamp it will look noticeably blue, which is why matching bulbs in one room helps.

Can I use it with a dimmer switch?

Yes, this is the dimmable version. Pair it with a trailing edge LED dimmer where you can, as older dimmers made for filament bulbs may flicker or hum at low settings.

Is an IP protection rating given for this bulb?

No. The manufacturer does not state an IP rating for this bulb, either on the specification or on the retail pack, so treat it as an ordinary indoor lamp.

How many bulbs come in a box?

One bulb per box, and the pack is marked as a single light. The order minimum on this listing is 12, in multiples of 12, so you receive twelve individually boxed bulbs.
