Normal kind of lamp (8)

I believe the answer is:

standard

I believe this is a double definition.

'normal' is the first definition.
(associated in meaning)

'kind of lamp' is the second definition.
(I've seen this before)

(Other definitions for standard that I've seen before include "sort of rose" , "Normal quality" , "type of flag" , "Ceremonial flag" , "Principle" .)

I've seen this clue in The Globe and Mail.
