An overview of ground illuminance distribution as produced by Full CutOff luminaires as offered on a Acuity Brands Lighting page. The file all_5.htm shows a photometric thumbnail overview for all of them, all_5_70.htm differs by being sorted on maximum cd/klm about 70 degrees. Clicking on any thumbnail opens a larger image.

Specific illuminances are coded logarithmically by colours. Each colour comprises one decadic order, shades within the colour are 0.5 mag each (so five shade steps are 2.5 mag, what corresponds to ratio of 1:10).

illuminance scale

Values below the scale are illuminance / 1 lx. This is for (unrealistic) “unit” case that luminaires would have lamps producing 1 klm only, would be point-like and just 1 m over the terrain. Amore realistic case would be lamps producing 10 klm each and being 10 m over the terrain: then the illuminances would be just 10× less.

The colour overview has been created using a Jan 2007 of ies2tab. The scripts ies?png.sh employed for image creation are within ../bin_exe directory.
