Country with one sort of candle (7)
I believe the answer is:
iceland
'country' is the definition.
(I know that Iceland is a country)
'with one sort of candle' is the wordplay.
'with' means one lot of letters go next to another.
'one' becomes 'i' (Roman numeral).
'sort of' indicates an anagram.
'candle' with letters rearranged gives 'celand'.
'i'+'celand' is 'ICELAND'.
(Other definitions for iceland that I've seen before include "North Atlantic country" , "Northern country" , "European island country" , "Land of geysers and Norse sagas" , "Its capital is Reykavik" .)
