Synonym discussion
Sense: noun/1
Lighting is the most general and practical word for how light is arranged in a space. Illumination is more technical and formal — an engineer might discuss 'illumination levels in a workspace,' but a homeowner talks about 'living room lighting.' Lights is the everyday plural noun for the physical fixtures themselves ('turn the lights on'), not the overall design. Lighting system is a broader term that includes the wiring, switches, and fixtures as a whole; it is used when installing or planning a setup. For everyday conversation about the look or feel of a room, lighting is the natural choice: 'The soft lighting in the café made it a great place to read.' For technical specifications, use illumination: 'The building's illumination meets international safety standards.'

Etymology
Lighting is the noun form of the verb light, which comes from Old English lihtan (to make bright or to shine). The root goes back to Proto-Germanic *leuhtą and further to Proto-Indo-European *lewk-, meaning 'to shine' or 'bright.' The first sense (arrangement of artificial light) appeared in the 1600s. The second sense (setting on fire) developed from the same verb light, which has also meant 'to ignite' since Old English times.
