| 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. | |
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.

# Bulbs: 1, 50000 lm each
# Number of measured angles: 31 vertical, 1 horizontal ones

# Luminaire flux = 36278 lm,
# 72.6 % of the bulb flux
# between 75 and 90: 1.4 % of the luminaire flux
# - this part causes just GLARE in case of road lighting and similar purposes
# 80deg and above: max 7.4 cd / 1000 lm , 0.4 % of the luminaire flux
# 90deg and above: max 0.1 cd / 1000 lm , 0.0 % of the luminaire flux
# CutOff Type: Full_CutOff
# 62.5 deg to <67.5 deg: max 213 cd / 1000 lm,
# 67.5 deg to < 76 deg: max 101 cd / 1000 lm,
# maximum spec. lum. intensity 315 cd / 1000 lm
# The following table gives luminous intensities which would be produced
