burn-in Explanation: You are parsing it wrong - it's burn in. It's a period of time that the lamps are operated before they reach a stable working state. -------------------------------------------------- Note added at 2 hrs (2015-07-29 16:32:42 GMT) -------------------------------------------------- As several people have noted, the 'a' should be removed. It would also work if you added 'for' before 'a'. |
