Energizer LED GLS Bulb B22 (BC) 7.3W Opal Dimmable - Daylight 6500K

This is a 7.3W LED GLS bulb with a B22 bayonet cap, the push and twist fitting most UK ceiling pendants and older table lamps use. It gives 806 lumens, which the pack rates as a replacement for a 60W filament bulb, so it is a like for like swap rather than a step down in light. The colour temperature is 6500K, described on the pack as daylight: a crisp, blue leaning white rather than the yellow of an old incandescent. Its outer is diffused white rather than clear, which spreads the light across the room and keeps the diodes from showing as bright points.

Daylight at 6500K is a working light. It suits kitchens, garages, utility rooms, workshops, home offices and hobby spaces, anywhere you want colours to read accurately and small print to stay legible late in the day. In a pendant over a worktop, or in a desk lamp, it keeps the light neutral and awake. It is a less natural choice for a bedroom or a sitting room, where a warm white bulb flatters the room more. If the room already has daylight bulbs in it, match them: two colour temperatures in one space reads as a fault rather than a choice.

The bulb is dimmable, and the pack carries a dimming icon to match the specification. LED dimming works best on a trailing edge dimmer rated for low loads; a rotary dimmer bought for filament bulbs may hum or lose the bottom of its range. The pack prints a 15,000 hour lifespan, shown as 15 years, and the energy rating is E. Each box holds one bulb, and the minimum order is 12, sold in multiples of 12, which suits relamping a house or keeping a few spares in the cupboard. It sits alongside our wider range of LED bulbs in other caps, including B15 candle and golf lamps and GU10 spots.

Will this fit my existing light?

It takes a B22 bayonet cap, the two pin push and twist base. Pull your old bulb out and check for two small pins on the sides rather than a screw thread.

What dimmer switch should I use with it?

A trailing edge dimmer rated for low wattage LED loads gives the smoothest result. Older rotary dimmers made for filament bulbs can hum or cut out near the bottom of the dial.

How bright is 806 lumens in practice?

It is the output the pack rates as a 60W filament replacement, so it suits a main ceiling pendant in an average sized room or a single bright task lamp.

What does 6500K daylight actually look like?

It is a cool, blue leaning white, close to overcast midday light. Colours read accurately under it, which is why it works well over worktops, benches and desks.

Is an IP rating given for this bulb?

The manufacturer does not state one, so treat it as an ordinary indoor bulb for dry domestic fittings and nothing more demanding than that.

How many bulbs do I receive?

Each box holds one bulb. The listing has a minimum order of 12 boxes, sold in multiples of 12, so you receive 12 single bulbs at the lowest quantity.
