It's about keeping right hole for illumination (5,5)
I believe the answer is:
strip light
'illumination' is the definition.
(I've seen this before)
'it's about keeping right hole' is the wordplay.
'about' says the letters should be written backwards.
'keeping' indicates putting letters inside.
'right' becomes 'r' (common abbreviation).
'hole' becomes 'plight' (both can mean a trouble or difficulty).
'its' back-to-front is 'sti'.
'sti' placed around 'r' is 'stri'.
'stri'+'plight'='STRIP LIGHT'
'for' is the link.
(Other definitions for strip light that I've seen before include "source of illumination" , "tube for the office" .)
