Clear LED GLS Bulb E27 A60 12W 1521lm Warm White

This is a clear LED GLS bulb with an E27 screw cap, in the familiar pear shape most people picture when they think of a light bulb. The glass is clear, so the slim upright LED filaments stay in full view, standing in a neat ring around a central glass stem. It measures 10.5cm long and 6cm across and draws 12W to give 1,521lm of warm white light at 2700K. Its IP rating is IP20, which settles where it goes: indoors, in dry rooms, inside a fitting kept away from water.

Because the filaments are on show, we like this bulb in fittings where the bulb is part of the look: a bare pendant on a flex, an open cage shade, a glass lantern or a wall light with a clear diffuser. At 1,521lm it gives a generous amount of light for a living room, a kitchen or a hallway, and the 2700K colour keeps the room warm and relaxed rather than stark, so it sits comfortably beside a reading chair or over a dining table. Any lamp holder with an E27 socket will take it, which covers a wide choice of ceiling pendants, table lamps and floor lamps.

The bulb pairs clear glass with a silver-toned screw cap, and it runs on 220-240V, 50/60Hz household mains. It is not dimmable, so put it in a light worked by an ordinary switch rather than a dimmer. It carries a D on the energy label. For care, with the power switched off and the glass cool, wipe it with a soft, dry cloth; clear glass shows dust more readily than frosted glass, and an occasional wipe keeps the filaments crisp and bright. Before you order, check the space inside your shade: at 10.5cm long and 6cm across, the bulb needs a little room around the glass.

Can this bulb go on a dimmer switch?

No. The bulb is not dimmable, so it belongs in a light controlled by an ordinary switch rather than a dimmer.
