*At recommended track distance from wall for corresponding ceiling height, wall washer will provide maximum illumination at eye level (5’- 6” above floor) when aimed 60° from horizontal (I.E.S. recommended practice).
† Footcandles shown in table for multiple units are based on a minimum of 5 units when on 18”, 27”, or 38” centers and 3 units when on 57”, 62”, or 93” centers.
Footcandles values are based on average room conditions.
