FITTING

The fitting, or lamp holder, is attached between the fixture and the intended light source. It is the connection and connector between the lamp and the light source. There are many types of fittings. Modern LEDs have a built-in light source; this does not involve a fitting.

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.
