What is the definition of the luminaire Spacing Criterion?
Luminaire Spacing Criterion is a term defined by the Illuminating Engineering Society of North America (IESNA) that is intended to indicate the largest ratio of the luminaire spacing to the mounting height (Spacing / Mounting Height) that can be achieved and still have even illumination underneath an array of luminaires. This value is generally reported in directions along and across the lamp axes. Thus, values are generally reported for horizontal angles of 0 and 90 degrees, and sometimes beyond depending on the symmetry of the luminaire.
