A room size of 45 m x 30 m has to be illuminated at a level of 500 lux on the working plane which is 4.6 m from the lamp. The utilization maintenance factor is 0.7. If the LDL output of each fitting is 6000 lumens. The space mounting ratio is 1:1. Calculate the number of fitting required and the fitting layout. Number of Lamps = Number of Rows = Number of Columns = Row to Row distance = Row to wall distance = Column to Column distance = Column to wall distance = Number of fittings =
