I've put the illuminance plots and luminous intensity tables to
It appears that the luminaire might be not bad for spacing 4 and less.
However, it is not 0 cd/klm, being 0,7 cd/klm at 90 degrees for one
direction. This should be improved before we recommend it. Sure it is
either a bug in measurement, or trivial imperfectness to correct.
The four wattages in the directory seem to have exactly same luminous
intensity distribution shapes.

PS. I've noticed tonight that the NPS has a real LP definition, wow! :
