Illuminance plots of LYDPR04C

(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.

# NONSENSE SUMMARY RESULTS of ies2tab: output flux is to be under 100 %!
# Source file: LYDPR04C.ies
# Luminaire flux =  4696 lm,
#                  100.0 % of the bulb flux
# between 75 and 90:  8.2 % of the luminaire flux
#  - this part causes just GLARE in case of road lighting and similar purposes
# 80deg and above:  max 237.4 cd / 1000 lm ,  2.5 % of the luminaire flux
# 90deg and above:  max   0.0 cd / 1000 lm ,  0.0 % of the luminaire flux
# CutOff Type: Fully_Shielded 

# 62.5 deg to <67.5 deg:   max   471 cd / 1000 lm,
# 67.5 deg to < 76  deg:   max   468 cd / 1000 lm,
# maximum spec. lum. intensity   510 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):
