# Bulbs: 1,   7950 lm each
#  (luminous intensites divided by  0.10 in the original ies file)
# Number of measured angles:  31 vertical,   1 horizontal ones
# Photometric type: 1,  Units type: 1
# Luminous openig width, length and height:   1.250   1.250   1.250
# Ballast factor: 1,  Input power:  175 W


# Source file: lxt1v55.ies
# Luminaire flux = 18676 raw, for the given bulb(s) it would be  1868 lx,
#                   23.5 % of the bulb flux
# between 75 and 90: 21.1 % of the luminaire flux
#  - this part causes just GLARE in case of road lighting and similar purposes
# 80deg and above:  max  27.2 cd/1000lm , 44.2 % of the luminaire flux
# 90deg and above:  max  24.1 cd/1000lm , 32.3 % 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:1091 %
#  Increase of Sky Luminance in Distant Places by light below 30.0 degrees
#    due to light going from the luminaire directly above horizon:2106 %
#  (for the zenith luminance such an angle suits places up to  10 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)

# Illumination of a rectangle of 0.0:1.0:-2.5:2.5 pole heights:
#  Per cent of luminaire output falling there:   14.2
#   for a unit case (glass at 1 m height, 1000 lm bulb) its illumination:
#  Maximum:    13.8 lx
#  Average:    6.7 lx
#  Minimum:    1.6 lx
#  Average/Minimum:    4.2

# The following table gives luminous intensities which would be produced
