Illuminance plots

produced from photometry file Lithonia_Lighting-Outdoor-Area-KSE-95020513.ies

spacing 5 plot spacing 6 plot single luminaire plot
In left plots, specific illuminances by a continuous row of luminaires spaced 5 and 6 heights are shown in their left halves (right half concerns 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.

# between 75 and 90:  4.1 % of the luminaire flux
#  - this part causes just GLARE in case of road lighting and similar purposes
