'started' is the definition.
(I've seen this in another clue)

'extremely loose party that was very loud' is the wordplay.
'extremely' says to hollow out the word (remove centre letters) (only the extremes of the word are used).
'party' becomes 'do' (do can informally mean a party).
'that was very' becomes 'f' (I can't justify this - if you can you should give a lot more credence to this answer).
'loud' becomes 'f' (short for forte - 'loud' in music).
'loose' with its middle taken out is 'le'.
'le'+'do'+'f'+'f'='LED OFF'
