round black wall or ceiling light - Ø 25 cm

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.
Check out here the complete collection of E27 light bulbs by zangra.

The light bulb is not included when you buy this light. You will find here the whole selection of LED, incandescent, stick and halogen light bulbs. Take into account that each light needs a specific type of light bulb. You will find the kind of light bulb that it requires under the "Technical Description" tab.

No screws are supplied, as the type of screw depends on the material of the wall or ceiling (concrete, brick, plasterboard, wood).
You need a different type of screws depending on each material.
