For lighting objects on a wall, the wall itself or any vertical surface, position the track and the fixtures as follows:
- Generally, fixtures should be aimed at a 30-degree angle from the vertical to prevent light from shining in anyone’s eyes and to avoid disturbing reflections on the surface of the object. Usually, one fixture is required for each object being accented.
- Measure the distance from the ceiling to the center of the object.
- Mount track at location from wall, on ceiling, as shown in the table. (Example: The distance from the ceiling to the center of the painting is 4 feet. Mount the track on the ceiling 27 inches away from the wall.)
For non-textured surfaces, mount the track 2 feet to 3 feet from the wall, on ceilings up to 9 feet high. Mount between 3 feet and 4 feet on ceilings between 9 feet and 11 feet high. Space the fixtures the same distance apart as the track is from the wall.
For dramatic shadows on textured surfaces (such as draperies, stone or brick), mount the track 6 inches to 12 inches from the wall, with the fixtures the same distance apart and aimed downward for a grazing effect.
General lighting can be provided by track fixtures aimed at the wall or by spill light from fixtures used for accent lighting or wall washing.
