Illuminance plots

produced from photometry file Lithonia_Lighting-Outdoor-Building_Mounted-Wfl3-Ltl8791.ies

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 = 16053 lm,
#                   54.0 % of the bulb flux
# between 75 and 90:  0.4 % of the luminaire flux
#  - this part causes just GLARE in case of road lighting and similar purposes
# 80deg and above:  max   9.4 cd/1000lm ,  0.1 % of the luminaire flux
# 90deg and above:  max   0.0 cd/1000lm ,  0.0 % of the luminaire flux
# CutOff Type: Full_CutOff    

# The following table gives luminous intensities which would be produced
# using a hypothetic bulb giving a luminous flux of 1000 lm (i.e., cd/klm):
