E27 (ES) LED GLS Bulb 8.5W 806lm Non-Dimmable - Daylight 6500K

This is a standard GLS bulb, the rounded household shape, with an E27 screw cap and a white opal dome rather than clear glass, so the light is diffused rather than pointed. It draws 8.5W and gives 806 lumens, which the pack states as a replacement for an old 60W incandescent bulb. The colour temperature is 6500K, a crisp daylight white with no yellow in it, and the pack prints a colour rendering index above 80. A 180 degree beam means light spreads out and down rather than pooling in one spot, so it fills a shade or a plain pendant evenly.

Daylight at 6500K reads as bright and clean, which suits places where you are doing something rather than sitting still: a kitchen, a garage, a utility room, a home office, a hallway that never gets much sun. It is a colder light than most living room and bedroom fittings want, so if you are mixing it with warmer bulbs in the same room the difference will show. An E27 cap is the larger of the two screw fittings used in the UK, the one you twist in rather than push and turn; check the base of your old bulb for a screw thread roughly 27mm across before ordering.

This bulb is not dimmable, so it needs an on and off switch; fitted to a dimmer circuit it may flicker, buzz or fail early. It carries an F energy rating and an IP20 rating, which means it is built for dry indoor fittings only. The pack states a life of up to 10 years. Each box holds one bulb and the minimum order is 12, sold in multiples of 12, which suits kitting out a whole house or keeping spares on the shelf. Our wider JCB LED range covers GLS, candle and golf shapes with B15, B22 and E14 caps in warm white, cool white and daylight.

Will this fit my existing light fitting?

It takes an E27 screw fitting, the larger of the two UK screw caps, so it suits pendants, table lamps and standard lamps whose old bulb screwed in with a thread about 27mm across.

How bright is 806 lumens in practice?

It gives 806 lumens from 8.5W, which the pack states as a 60W replacement, so it is a sensible single bulb for an average room or a hallway.

Can I put it on a dimmer switch?

No. The specification gives it as non-dimmable, so pair it with an ordinary on and off switch; a dimmer circuit can cause flicker, buzz or early failure.

What does 6500K daylight look like next to a normal bulb?

It is a clean white with no warmth in it, noticeably colder than the 2700K and 3000K bulbs most homes use, which makes detail easier to see when working.

How long does the manufacturer say it lasts?

The pack states a life of up to 10 years, and the specification gives an F energy rating for the 8.5W draw.

How many bulbs do I receive?

Each box contains one bulb. The minimum order on this listing is 12 boxes, sold in multiples of 12, so you receive 12 bulbs.
