    The document provides sample calculations for lighting layout and design. It calculates the transverse spacing between lights as 2.53 meters and the total length of each row as 12.65 meters. It then determines the space needed at the ends of each row is 1.175 meters. Finally, it calculates the total number of lights needed as 186 based on spacing 6 lights across 31 rows.

    Sample Calculations Sample Calculations

    Transverse spacing = 15m - 2(1.175m)/5 Draw plan of the room and indicate the locations of luminaries.

    = 2.53 m

    Total length of each row = 5 x 2.53m


    = 12.65 m

    Space at ends of row = (15 - 12.65)/2


    = 1.175m

    Total number of luminaries = 6 x 31


    = 186 luminaires
