When luminaires have
been sited to cover the location above, additional luminaires may be required
to ensure minimum lighting levels areachieved
We provide spacing
tables for this purpose. Spacing tables advise how far to locate the first
luminaire, then how far apart other luminairesshould be located for
a given mounting height. Installation to the spacings will ensure the lighting
levels will be achieved
