Illuminance plots of RGAI61

(as computed by ies2tab from that photometry file)

spacing 5 plot spacing 6 plot single luminaire plot
In left plots, specific illuminances by a continuous row of luminaires spaced 5 and 6 heights are shown in their left halves (right half concerns 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.

# Luminaire flux =   725 raw, for the given bulb(s) it would be 10876 lm,
#                   72.5 % of the bulb flux
# between 75 and 90:  6.8 % of the luminaire flux
#  - this part causes just GLARE in case of road lighting and similar purposes
# 80deg and above:  max 207.0 cd / 1000 lm ,  1.4 % 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   412 cd / 1000 lm,
# 67.5 deg to < 76  deg:   max   663 cd / 1000 lm,
# maximum spec. lum. intensity   663 cd / 1000 lm
