Lines: 7 The question recently came up here of the minimum duration of absence from a room (an office in this case) that justifies turning off the fluorescent lighting. I turn them off whenever I'm going to be gone for more than two or three minutes. One fellow said he had heard that you should leave them on unless you'd be gone for more than forty-five minutes. Is there someone out there who can provide a firm answer to the question?
