7W E27 GLS LED Filament Bulb - Warm White 2700K

This is a 7W LED filament lamp in the classic GLS shape, with an E27 screw cap and clear glass. Four straight filament rods run the length of the bulb, so you see the light source rather than a diffuser, which is the point of a clear lamp in an open shade or a bare pendant. It gives 806 lumens at 2700K, the warm white most people recognise as ordinary domestic light, and the retail pack rates that output against a 60W conventional bulb. The beam spreads across 280 degrees, close to the all round throw of the filament bulb it replaces.

That wide spread makes it a general room lamp rather than a directional one. It suits ceiling pendants, table and floor lamps, and any fitting where the bulb itself is on show behind glass or an open shade. E27 is the larger of the two common screw caps used in the UK, sometimes printed as ES on a fitting; if the bulb you are replacing has a screw base rather than two push and twist pins, this is the cap to match. One thing to check first: the pack states the lamp is not dimmable, so it needs a plain on and off switch rather than a dimmed circuit.

The pack quotes a rated life of 10,000 hours and more than 8,000 on and off switching cycles, which matters more than raw hours in a hallway or on a stairwell where the switch is used constantly. Colour rendering is given as CRI above 80, and the voltage as 220 to 240V at 50/60Hz. The energy label reads class E, with consumption of 7kWh per 1,000 hours. The rating is IP20, which offers no protection against water, so keep it to dry indoor fittings. Eveready supplies it as a single lamp, one per box, and we sell it in multiples of five.

How do I know if my light fitting takes an E27 bulb?

E27 is a screw cap, the larger of the two screw sizes sold in the UK, and it is often marked ES on a fitting. If the old bulb twisted out rather than pushing and turning on two pins, E27 is the one to match.

How bright is 806 lumens compared with an old bulb?

The retail pack rates this lamp against a 60W conventional bulb, so 806 lumens is the everyday brightness most people expect from a main pendant or a floor lamp in a living room or bedroom.

Can I put it on a dimmer switch?

No. Both the supplier specification and the retail pack state that this lamp is not dimmable, so it needs a standard on and off switch rather than a dimmed circuit.

Is 2700K a warm or a cool light?

2700K is warm white, the softer yellow toned light associated with older household bulbs. It reads as relaxed rather than crisp, which suits living rooms, bedrooms and hallways more than a task area.

Why does an LED carry an energy class of E?

The class is read from the label supplied with the lamp. That scale runs A to G and is set so very few lamps of any type reach the top bands; the figure worth comparing is 7kWh per 1,000 hours.

Where in the house can I use it?

It is rated IP20, which gives no protection against water, so it belongs in dry indoor fittings such as pendants, table lamps, floor lamps and enclosed wall fittings rated for a 7W lamp.
