yellow lamp holder with ribbed stick bulb

These tubular lamps by Belgian brand zangra are available in several colours and are particularly suited for mirror lighting.
This rectangular surface-mounted light fixture is topped by a tubular light bulb with an S14d base.
zangra designed this model based on the historic Linestra linear lamp from the 1930s. Since then, new LED bulbs have replaced the former Linestra incandescent bulbs.
You can choose between a 30cm or 50cm light bulb.

The small rectangular lamp holders in which the tubular lamps are integrated are available in two different versions: the S14s model and the S14d model.
The 30 cm and 50 cm stick light bulbs offered by zangra have a single base (a pin). The 1-metre stick light bulbs have two bases (two pins).
For 30 cm and 50 cm stick light bulb, you need a single S14d lamp holder. 1-metre linear light bulb have two pins, so you need two S14s lamp holders.

The lamp holders are usually made of plastic or metal, zangra has designed a very aesthetic version in white and black porcelain.

All light fittings are classified according to their IP value. These IP values (International Protection or Ingress Protection) indicate the degree of protection of the light fitting against dust and moisture. The IP value consists of two digits: the first digit indicates the level of protection against dust; the second, the level of protection against moisture. The higher the IP value, the higher the protection. Check this diagram to see the different existing IP values.
 

What does the IP20 value mean on this light fitting?

IP20 means that the light fitting:
