Energizer LED GLS B22 3.8W Filament Non-Dimmable - Daylight 6500K

This is a B22 bayonet cap LED bulb in the familiar GLS shape, the rounded pear outline that has sat in ceiling pendants and table lamps for decades. Inside the clear glass sit LED filament strips rather than a frosted diffuser, so the light source stays on show and the bulb reads much like the tungsten lamp it replaces. It draws 3.8W and gives 806 lumens, which the pack describes as 806 lumens in a sphere, at a colour temperature of 6500K. The pack states it as a 60W replacement, and the energy label carries an A rating at 4 kWh per 1000 hours.

6500K is daylight, the coolest and cleanest of the white tones, with a blue-white cast rather than the yellow of a traditional bulb. It suits places where you want to see clearly: a home office, a garage or workshop pendant, a utility room, a hallway that never gets much natural light, or a craft table where colour matching matters. It is a deliberate choice rather than a default, so if the neighbouring rooms run on warm white bulbs, expect a clear difference where the two meet. Clear glass and a visible filament also look right in an open shade or on a bare flex.

This bulb is not dimmable, and the pack says so plainly, so pair it with a standard on/off switch rather than a dimmer circuit; putting a non dimmable lamp on a dimmer can cause flicker and shorten its life. The pack prints a 50 year lifespan, based on the manufacturer's own stated hours of use. One bulb comes in each box, and the minimum order is 12, sold in multiples of 12, which suits anyone kitting out a whole property or keeping spares on a shelf. We also stock LED bulbs in B15 candle and golf shapes and GU10 spotlights.

Will this fit my existing bayonet light fitting?

Yes, if the old bulb has two small pins on the side of a smooth metal cap and pushes in with a quarter turn, that is B22 and this bulb matches it.

How bright is 3.8W, and what bulb does it replace?

It gives 806 lumens, and the pack states it as a 60W replacement, so it is the usual choice for a main ceiling pendant in a bedroom or a landing.

What does 6500K daylight actually look like?

Crisp and blue-white rather than yellow. It shows detail and true colours well, which helps for reading, sewing or working, but it feels brisk in a relaxing room.

Can I use this bulb with a dimmer switch?

No. The pack marks it non dimmable, so use it on a plain on/off switch. On a dimmer circuit it may flicker, buzz or fail early.

Does the manufacturer state an IP rating?

No IP rating is printed on the pack or given in the specification, so we state none. Treat it as an ordinary indoor lamp for dry, enclosed or open fittings.

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

Each box holds one bulb. The minimum order is 12 boxes, sold in multiples of 12, so you receive twelve individually boxed bulbs at the lowest quantity.
