1 Ceiling height is constant at 9 feet. Actual fixture mounting height is 8' and 9' respectively to where top of fixture is suspended. Photometric center where data is first measured out of the luminaire is 86.5" to floor for 8' and 98.5" to floor for 9' mounting heights. 2 Values indicated when used with two fixtures per bay and house side shield accessory, pointed towards exterior of garage. Value represents the average foot-candle reading along very edge of garage floor. 3 Taken from prorated data. 4 Footcandle data points are spaced 12" center to center.
