Illuminance plots of 2591

(as computed by ies2tab from that IES photometry file)

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.

# REPORT: CI2032  
# DESCRIPTION: 1605 FLC 20 EL
# LAMP: FLC20EL             
# TILT=NONE
# Bulbs: 1,   1200 lm each
#  (luminous intensites divided by  1.20 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:   0.000   0.000   0.000
# Ballast factor: 1,  Input power:   20 W


# Source file: ies/2591.ies
# Luminaire flux =   490 raw, for the given bulb(s) it would be   588 lm,
#                   49.0 % of the bulb flux
# between 75 and 90:  3.1 % of the luminaire flux
#  - this part causes just GLARE in case of road lighting and similar purposes
# 80deg and above:  max  14.0 cd / 1000 lm ,  1.2 % 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    55 cd / 1000 lm,
# 67.5 deg to < 76  deg:   max    40 cd / 1000 lm,
# maximum spec. lum. intensity   185 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):
