Clear Dimmable LED GLS Bulb E27 A60 9W 1055lm Warm White

This is a clear glass LED filament bulb in the classic GLS shape, the rounded pear outline most people picture whenever they think of a light bulb. It measures 10.5cm long and 6cm in diameter, with an E27 screw cap, so check that your lamp holder takes an E27 bulb before you order. Inside the glass, four straight filaments stand around a slim glass stem and draw just 9W to give 1,055 lumens of warm white light at 2700K. The IP20 rating settles where it belongs: indoors, in dry rooms, in a pendant, table lamp, floor lamp or wall light.

Because the glass is clear, the filaments become part of the look, which makes this bulb a sound choice wherever it will be seen: a bare pendant over a dining table, an open cage shade or a wall light without a diffuser. At 1,055 lumens it gives a generous light for a living room, kitchen, hallway or bedroom, and 2700K is the warm, slightly golden white that suits evenings at home. We like it for anyone replacing older bulbs one at a time, as the shape stays familiar in the shade while the 9W draw keeps the electricity it uses low.

The bulb is dimmable, so on a suitable dimmer switch you can bring it down to a soft glow for a quiet evening and back up for reading or cooking. Dimmers made for older bulbs do not always suit LEDs, so it is worth checking that yours is rated for LED loads. It runs on 220-240V, 50/60Hz mains and carries energy class D. The clear glass keeps the filaments visible from every angle, and the screw cap is silver coloured. Before ordering, measure the inside of your shade, as the bulb needs 10.5cm of length and 6cm of width to sit comfortably.

Which cap does this bulb have?

It has an E27 screw cap, the larger standard screw size, so it suits lamp holders made to take an E27 bulb.

Can this bulb be dimmed?

Yes, it is dimmable. Use it with a dimmer switch rated for LED loads to bring it from a low glow up to full brightness.

How bright is the light?

It gives 1,055 lumens from 9W, in a warm white of 2700K, which is plenty for a main ceiling pendant in a living room or bedroom.

Can I use it in a bathroom or outdoors?

No. It is rated IP20, which means it belongs indoors in dry rooms, away from splashing water and the weather.

How big is the bulb?

It is 10.5cm long and 6cm in diameter, the familiar GLS shape, so measure your shade to be sure it has room for both.

Why choose a clear filament bulb?

With clear glass, the four straight filaments stay on show, so it looks good in a bare pendant, an open cage or any shade that leaves the bulb visible.
