Question:
In some cases in order to comply with the thermal requirements, the manufacturer prescribes a large separation between the lamp enclosure and control gear (distance “a” in figure D.1), and also the use of detachable spacers.
1 - Which is the distance limit according to the common sense? Could be recommended a distance of 1 m, 2 m or more?
2 - In a F marked luminaire shall we consider these spacers or, as the standard says, the top of the luminaire shall be in contact with the inside top of the test recess?
Decision:
Use common sense: we recommend a distance of maximum 0,5 m.
