Dimmable LED Bulb E27 4W 40lm Warm White - Black

This is a bulb to be looked at as much as used. The glass is tinted a smoky black and shaped into a rounded, softly irregular form that widens towards the top, a little like a pebble, and inside it a single LED filament curls into a spiral on a slender stem. It measures 25.5cm long and 19cm across, with a brass-coloured E27 screw cap at the base, the larger Edison screw size. It draws 4W and gives 40 lumens at 2000K, a deep amber shade of warm light. With an IP20 rating it belongs indoors, in a dry room.

Because the tinted glass softens the filament and 40 lumens is a gentle glow, this is a bulb for atmosphere rather than a working light for reading or cooking. Hang it bare from a pendant over a dining table, cluster a few at different heights, or set it in a simple table lamp holder where the glass does the decorating. It suits bare-bulb and open fittings in living rooms, dining rooms, hallways and bedrooms, anywhere a warm, low light sets the mood in the evening. Before you buy, measure the space inside any shade you have in mind, since a bulb this size needs room around it.

The glass is the shade here: when lit, the spiral filament shows as a fine amber line through the smoky tint, and whenever the bulb is unlit it reads as a piece of dark glass. It is dimmable, so on a dimmer switch you can bring it lower still for a candlelit feel at the table. It is made for 220-240V, 50/60Hz mains supplies, and its packed weight is 0.551KG. Glass wipes clean with a soft, dry cloth, and a light dust now and then keeps the tint looking clear.

Can this bulb go in a bathroom or outdoors?
