| 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.
# REPORT: CI1148
# DESCRIPTION: 1103 SAP-T 250
# LAMP: SAPT250
# TILT=NONE
# Bulbs: 1, 27500 lm each
# (luminous intensites divided by 27.50 in the original ies file)
# Number of measured angles: 37 vertical, 24 horizontal ones
# Photometric type: 1, Units type: 2
# Luminous openig width, length and height: 0.295 0.370 0.000
# Ballast factor: 1, Input power: 250 W
# Source file: ies/2370.ies
# Luminaire flux = 639 raw, for the given bulb(s) it would be 17562 lm,
# 63.9 % of the bulb flux
# between 75 and 90: 1.9 % of the luminaire flux
# - this part causes just GLARE in case of road lighting and similar purposes
# 80deg and above: max 11.0 cd / 1000 lm , 0.8 % of the luminaire flux
# 90deg and above: max 0.0 cd / 1000 lm , 0.0 % of the luminaire flux
# CutOff Type: Full_CutOff
# 62.5 deg to <67.5 deg: max 57 cd / 1000 lm,
# 67.5 deg to < 76 deg: max 41 cd / 1000 lm,
# maximum spec. lum. intensity 284 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):
