No One Appears To Know

How far off the floor and away from the wall do fluorescent lights have to be before they are required to have covers? And where is the standard for such an issue?

No appears to know the answer to this question.

Commercial kitchens and food prep areas.

i prolly don’t know either
too many variables, can u be more specific on bldg usage & room/location
luminaire ip & ik, nema & ul…all rate fixtures by mechanical & liquid impact or resistance
luminaires below 80" that protrude into a walk/pathway would be asking for trouble
persons taller are ignored by code as far as i know
