| | | Effective wall lighting can be accomplished using either directional lamps with wider distributions or special wall wash luminaires using omni-directional lamps positioned in special fixture reflector optics. | | |
| | | |
| | | Wall Washing Wall washing provides even, diffuse Illumination of vertical surfaces such as walls, perimeter merchandise displays, signage and large artwork. To achieve uniform wall washing, trac fixtures using lamps with flood distribution patterns are generally spaced apart equal to the distance the trac is mounted away | | |
| | | from the wall. The trac should be positioned to preserve an approximate 30° aiming angle. Refer to the setback chart in the Accent Lighting section for placement guidelines. Trac fixtures can also be spaced further apart to create a more distinct pattern of "light scallops" to create visual interest or a sense of scale. | | |
| | | |
| | | Directional Flood Lamps Incandescent BR, PAR, and MR16 lamps can be effectively used to illuminate vertical surfaces creating different effects. | | Grazing By placing trac 6"-12" from a wall, a more dramatic grazing effect can be achieved on textured surfaces such as brick, stone or stucco. PAR and MR lamps are a good source for grazing. (Note: Grazing is not recommended on smooth surfaces, as it will magnify any surface imperfections.) | | |

| | | |
| | | Rectangular Flood Fixtures Rectangular flood fixtures using fluorescent or ceramic arc metal halide lamps create the most energy efficient, uniform wall illumination possible. Rectangular floods are the most appropriate solution for retail and commercial spaces and are | | |
| | | often used in combination with spotlights to highlight merchandise or objects for the best blend of efficiency and visual impact. Refer to the photometric section in this catalog for charts showing recommended fixture spacings, trac setback from the wall and illumination levels. | | |
