| 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.

# Luminaire flux = 610 lm,
# 92.4 % of the bulb flux
# between 75 and 90: 0.2 % of the luminaire flux
# - this part causes just GLARE in case of road lighting and similar purposes
# 80deg and above: max 1.5 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):
