Energizer LED GLS B22 7.2W Filament Non-Dimmable - Daylight 6500K

This is a B22 bayonet cap LED bulb in the familiar GLS shape, the rounded household profile that has sat in pendants and table lamps for decades. Inside the clear glass are LED filament strips rather than a frosted diffuser, so the light source itself is part of the look. It draws 7.2W and gives 1521 lumens, and the retail pack presents it as a replacement for a 100W incandescent bulb. The colour temperature is 6500K, the coolest looking white on the usual scale, which the pack calls daylight. The energy label rates it A, with consumption of 8 kWh per 1000 hours.

B22 is the bayonet cap: two pins on the side of a smooth metal base that push in and twist a quarter turn, rather than the E27 screw thread. Check the old bulb first, because the two caps look similar and will not swap. A clear filament bulb is worth choosing where the bulb is on show, in an open shade, a glass lantern, a pendant on a long flex or a bare batten fitting. The 6500K white is crisp and neutral rather than cosy, which makes it a sensible pick for a kitchen, a utility room, a garage, a workshop or a stairwell where you want to see clearly. In a bedroom or a snug, a warm white lamp usually suits better.

The pack marks the bulb non-dimmable, so wire it to a plain on and off switch and keep it away from dimmer circuits. The pack also prints a 50 year lifespan, worked out on the manufacturer's own usage assumptions. Each box holds a single bulb, and the minimum order is 12, sold in multiples of 12, which suits doing a whole house or holding spares. We stock other LED bulbs in GU10 and in B15 (SBC) candle and golf shapes if you have mixed fittings to fill.

How do I tell whether my fitting takes a B22 cap?

Look at the base of the old bulb. A B22 has a smooth metal barrel with two small pins on the side and pushes in with a quarter turn, while an E27 has a screw thread.

Will 1521 lumens match the old 100W bulb I took out?

The pack presents this 7.2W lamp as a 100W replacement, and 1521 lumens is the brightness figure to compare against. Lumens, not watts, are what tell you how much light you get.

Can I put it on a dimmer switch?

No. The pack marks it non-dimmable, so it is made for a plain on and off circuit. If you need dimming, choose a lamp that states dimmable on its own pack.

What does 6500K daylight look like in a room?

It is a crisp, slightly blue-leaning white that makes colours and detail easy to read. It suits working areas far better than a room where you want a soft, cosy glow.

Is an IP rating given for this bulb?

The manufacturer does not state one, so we quote none. It is an ordinary indoor household lamp for dry, sheltered positions in normal enclosed or open shades.

How many do I have to order?

The minimum order is 12 units of this listing, sold in multiples of 12, and each unit is a box containing one bulb, so twelve is twelve bulbs.
