In a warehouse, lights are mounted 4 meters above the floor. This provides an average light level of 150 lux. To increase the light level without installing more lights or higher Wattage lights, you lower the light fixtures with pendants so that the lights are located 3.25 meters above the floor. Calculate the new average light level on the floor.
