Just one quick note about fluorescents. Their life is directly related to the number of thimes they are turned on. One of our storage areas was designed with motion detectors and those bulbs have a much shorter life than ones that are left on for longer periods. Considering that the majority of energy useage also happens at start-up, it is probably more efficient from both an energy and equipment cost standpoint to leave Flourescent lights on if someone will need it on within a reasonable time.
