Illuminance plots of prmsh4

(as computed by ies2tab from that IES photometry file)

spacing 5 plot single luminaire plot
In the left half of the left plot, specific illuminance by a continuous row of luminaires spaced 5 heights is shown (right half is for a single luminaire). The right plot is for a single luminaire, unrotated.

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.

# Luminaire flux =  1092 raw, for the given bulb(s) it would be 10813 lm,

#  - this part causes just GLARE in case of road lighting and similar purposes
# 80deg and above:  max   8.7 cd/1000lm ,  0.5 % of the luminaire flux
