A uniform illumination of 150 lux is to be obtained on the floor of a room measuring 15m x 15m by arranging electric lights suitably. Calculate the number of lamps and wattage of each lamp if lamp efficiency is 20 lumens/watt. Assume and write suitable values of constants required for this calculation.
