# Bulbs: 1,  20500 lm each
# Number of measured angles:  47 vertical,   1 horizontal ones
# Photometric type: 1,  Units type: 1

# Luminaire flux = 10402 lx,
#                   50.7 % of the bulb flux
# between 75 and 90: 28.0 % of the luminaire flux
#  - this part causes just GLARE in case of road lighting and similar purposes
# 80deg and above:  max  98.0 cd/1000lm , 26.6 % of the luminaire flux
# 90deg and above:  max  42.0 cd/1000lm , 12.9 % of the luminaire flux
# CutOff Type: CIE_Semi-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: 451 %
#  Increase of Sky Luminance in Distant Places by light below 30.0 degrees
#    due to light going from the luminaire directly above horizon: 929 %
#  (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:   10.2
#   for a unit case (glass at 1 m height, 1000 lm bulb) its illumination:
#  Maximum:    14.9 lx
#  Average:   10.3 lx
#  Minimum:    5.8 lx
#  Average/Minimum:    1.8

# The following table gives luminous intensities which would be produced
# using a hypotetic bulb giving a luminous flux of 1000 lm (i.e., cd/klm):
