Light source including

This indicates whether or not the light source is included as standard. If the light source(s) are not included, you will find the corresponding lamp in the accessories

POWER SUPPLY / DRIVER

A power supply is the part of the lamp that changes the input voltage (coming from the mains). The input voltage is made suitable for the various components of the lamp. Often the voltage is transformed into another voltage. A power supply can also convert AC voltage to DC voltage (or vice versa). If no transformations are needed (as with an incandescent lamp), no power supply or driver is required. It is called an adapter if the conversion does not occur in the device itself but by a separate device.

IP VALUE

The IP value indicates the degree to which electrical devices such as lighting fixtures are protected against solid objects and water.
An IP (InternalProtection) value always consists of two digits.

The first digit indicates the protection against solid objects.
The second digit indicates the degree to which the device is protected against water.

If a device is well sealed against water (second digit), then it is difficult for solid objects to enter the device (first digit).
A high second rating is therefore always accompanied by a high first rating.
A lighting fixture that you want to use outside or in the bathroom therefore requires a higher IP value.
Thus the bathroom is divided into four imaginary safety zones, each with their own required IP value.
