LED light bulb - ribbed glass - 31cm

This elongated light bulb is made of ribbed glass. The fine vertical ribs create a subtle linear pattern, even when the bulb is switched off. Thanks to its standard E27 screw base, it fits light fixtures with an E27 socket.

Available in three lengths: 18 cm, 31 cm and 50 cm. It looks great as a standalone statement piece, but is also particularly decorative when different sizes are combined.

E27 stands for the type of the fitting of a lamp. E27 stands for a 27 mm diameter thread. "E" stands for Edison thread. So you always have to put an E27 light bulb in a fixture with an E27 fitting. E27 is the standard in England and most European countries.
The early light bulbs (remember them?) had a similar screw thread.
Be careful though, because there are also countries where E26 bulbs are the norm (for example in the United States).
If you would like to know which standard applies in your country, check out this page.
