E27 (ES) LED GLS Bulb 7.3W 806lm Non-Dimmable - Warm White 2700K

This is a GLS bulb, the classic pear shape that has lit British homes for generations, built now as an LED drawing 7.3W. It gives 806 lumens, which the pack rates as the equal of an old 60W incandescent, and it takes an E27 screw cap, the larger of the two screw fittings in common UK use. The glass is opal rather than clear, so the diodes inside read as an even glow rather than bright points. The pack quotes those 806 lumens in a sphere, meaning the output is measured all round the bulb rather than as a single forward figure.

E27 is the cap on most pendants, table lamps, floor lamps and drum shades sold here. If you are unsure, take the old bulb out and look at the base: a screw thread roughly 27mm across is E27, while a narrower one is E14 and needs a different bulb. The 240 degree beam angle is worth noticing. A spotlight throws around 36 degrees; this spreads light almost the whole way round, which is what a shade or a ceiling rose needs if a room is to be lit evenly. At 2700K the light is warm and slightly golden, the tone most people want in a living room, a bedroom or a hallway after dark.

This one does not dim. The pack marks it non dimmable, so run it from an ordinary on and off switch; on a dimmer circuit a bulb not rated for dimming can flicker, buzz or fail early. The pack prints a 15,000 hour life, shown there as 15 years, and the energy class is E. Each box holds one bulb and the minimum order is twelve, so it suits stocking up or changing a whole house at once. It sits alongside our wider range of Energizer LED bulbs in candle, golf and GU10 forms.

Will this fit my existing lamp or pendant?

It fits any E27 holder, also called ES or Edison screw, which is the wide screw cap used on most UK pendants, table lamps and floor lamps. Check the old bulb: a thread about 27mm across is E27, a narrower one is E14.

Is it really as bright as a 60W bulb?

The pack rates it as a 60W replacement, and 806 lumens is the figure the industry settled on as the LED equal of a 60W incandescent. Judge LEDs on lumens rather than watts, since watts only tell you what the bulb consumes.

Can I put it on a dimmer switch?

No. The pack marks it non dimmable, so it needs an ordinary on and off switch. Fitted to a dimmer circuit, a bulb without a dimming rating may flicker, hum or shorten its life, so choose a dimmable version for that circuit.

What does 2700K warm white actually look like?

It is the soft, faintly golden light people associate with an old filament bulb, comfortable in living rooms and bedrooms. Cooler options at 4000K or 6500K look crisper and whiter, and suit workshops or garages more than a sitting room.

Does the wide beam angle make a difference in a shade?

Yes. At 240 degrees the light travels sideways and backwards as well as down, so a fabric shade or a ceiling rose glows evenly instead of casting one bright pool directly beneath the fitting.

How many bulbs do I receive, and how many must I buy?

Each box contains one bulb. The minimum order on this listing is twelve boxes, sold in multiples of twelve, which works out at twelve individual bulbs delivered to you.
