8” absolute minimum but closer to 12” typically above the ceiling. It also depends on the lay-in light fixtures purchased and clearances required for removal.

Is your preference to run as low as possible above the depth of the lights to save on pipe, to run a fixed height above the ceiling (ie: 8", 12", 14") to simplify cut lengths, just run anywhere in between the lights and ductwork, or something else? I've heard a few different approaches to this question and was curious what considerations our experts here make when determining how high to run. Thanks in advance. -- Joseph Meyer, P.E.
