10. A Drawing room with dimension 15x6x3 meter. The required illumination level is 500 Lux. The working plane is 2.2 meter bellow the lamps. Assume the utilization factor, the maintenance factor are 0.6 and 0.8 respectively. The available fluorescent luminaires are 2*24 watt of 160 lumen/watt light efficiency and 90 % power efficiency at 0.7 lagging power factor. Draw a schematic diagram for lamps distributions. Calculate the circuit current and number of lamps.
