| 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. |
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.

# Source file: HARMONY_HAC-VTC-RETROLED-AREA-WRN_36_DS-NW_36_4250_NW_LED.ldt
# Luminaire flux = 794 raw, for the given bulb(s) it would be 3373 lm,
# 79.4 % of the bulb flux
# between 75 and 90: 4.0 % of the luminaire flux
# - this part causes just GLARE in case of road lighting and similar purposes
# 80deg and above: max 20.5 cd / 1000 lm , 5.3 % of the luminaire flux
# 90deg and above: max 19.9 cd / 1000 lm , 3.3 % of the luminaire flux
# CutOff Type: IES_CutOff
# Increase of Sky Luminance due to light going
# from the luminaire difectly above horizon, as compared with the
# luminance produced by the light dispersed from the ground: 83 %
# Increase of Sky Luminance in Distant Places by light below 15.0 degrees
# due to light going from the luminaire directly above horizon: 339 %
# (for the zenith luminance such an angle suits places up to 19 km distance)
# The increases concern the following situation:
# Albedo = 0.10
# Zenith Extinction = 0.30 mag (i.e., direct light remaining 76 %)
# Indicatrix type =0 (0: acc. to P.Cinzano, 4..6: CIE sky types)
# (the downward-scattered part of lambertian uplight is 0.1108 then)
# 62.5 deg to <67.5 deg: max 323 cd / 1000 lm,
# 67.5 deg to < 76 deg: max 320 cd / 1000 lm,
# maximum spec. lum. intensity 323 cd / 1000 lm
# 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):
