Lighting

For Type Cataloging Initial Intensity Parameters in spreadsheets prior to comma separated value export, see these sample spreadsheets.

Luminous Flux = Wattage ÷ Efficacy
Illuminance = Luminous Intensity ÷ 9.29 (1 square which is equal to approximately 9.29 square metres)
Luminous Intensity = Luminous Flux ÷ 12.5663706 (Solid angle of a complete sphere or 4π steradian which is approximately 12.5663706)
