The term ‘lighting’ refers to equipment the primary purpose of which is to produce light. This is typically some form of lamp. However lighting can also refer to the use of natural light to provide illumination.

The level of light on a surface is described as ‘Illuminance’ and is measured in lux (lx), where one lux is equal to one lumen per square metre (lm/m^2) and a lumen is the SI unit (International System) of luminous flux, describing the quantity of light emitted by a lamp or received at a surface.
