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:
2: is protected against the intrusion of solid particles with a dimension greater than 12.5 millimetres.
0: has no protection against water penetration.

This light fitting can be installed indoors, but not in wet areas.
It is not recommended to install this light fitting outdoors.

A device with an IP20 value is not protected against dust or moisture. A light fitting marked IP20 may have holes to prevent overheating. However, the lamp is protected against contact with objects larger than 12.5 mm, such as a hand or finger.
This model is suitable for indoor use, but not outdoors.

A GU10 light bulb is designed for GU10 or GZ10 fittings. These light bulbs are commonly used for spotlights. The GU10 light bulb employs a twist-and-lock system, called Bi-Pin, which consists of two prongs spaced 10 mm apart. U means "Universal". They operate at 230 volts without the need for a transformer or a driver. If your light bulb is dimmable, you will be able to adjust the brightness at all time. It’s designed to fit snugly into place with just a push and a clockwise twist.
