# Photometric conversion with spectral data
# Scope: Monochromatic radiometric-to-luminous conversion with supplied photopic weighting.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

radiantPower = 1 W
photopicWeight = 0.8
efficacy = 683 lm/W

lumens := radiantPower*photopicWeight*efficacy [lm]

check luminous flux target: lumens >= 500 lm

scenario alternative: radiantPower = 0.8 W
