You want to have an illuminance of 600 lux on the Beauty and the Beast (under the SPOTLIGHT#2). What is the Luminous Flux (lumen) the lamp need to releases assuming homogeneous distribution of the light in the illuminated circle? Given the following scene on the stageSpotlight #11 meter diameterSpotlight #22 meters diameterBoth spotlights SPOTLIGHT#1 and SPOTLIGHT#2 are place at 20 meters from the stage. You wantto produce a circle of light of 1meter diameter with the SPOTLIGHT#1and a circle of light of 2meters diameter with the SPOTLIGHT#2

Given, Illuminance of spotlight 2 = 600 luArea of the circle as, = π×22/4 = πm2 Luminous flux = Illuminance × Area = π m2× 600 lumens/m2 = 600π lumens = 1884.9556 lumens

Answered: and the Beast (under the SPOTLIGHT#2).…
