Crossword Genius

Coming down to provide illumination (8)

Ross

I believe the answer is:

lighting

I believe this is a double definition.

'coming down' is the first definition.
(lighting is a kind of coming down)

'illumination' is the second definition.
(lighting is a kind of illumination)

'to provide' is the link.

(Other definitions for lighting that I've seen before include "See 14" , "Visual aids" , "landing" , "Illumination" , "What bulbs can provide" .)

I've seen this clue in The Telegraph.
