Quizplus · Accepted Answer

Correctly placed occupancy sensors can detect movement and ensure that the fluorescent lamps switch on quickly, which can create a safer environment. Option A is incorrect because some sensors can detect people through infrared and microwave technology. Option B is incorrect because frequent switching of fluorescent lighting can work with the proper equipment. Option D is incorrect because some automatic sensing systems can work efficiently with fluorescent lights, and people do not have to walk into a dark room. Option E is also incorrect because unoccupied rooms should not have lighting on all the time as it is wasteful and unnecessary.
