Specialty Lighting Industries aspires to provide specifiers with their ideal in lighting equipment. Every product in our extensive line has been tailor made to specifiers' exacting demands. It is our purpose to provide precisely what the most demanding of designers need to make their project succeed at the highest level of performance and appearance.

Commitment to the Future

We are indebted to the many lighting designers and architects who trusted us to develop unique products that helped distinguish their projects from the ordinary. We wish to express our gratitude to them for the part they played in the development of our product line. The additions to our professional staff represent a major commitment to improving efficiency. While providing timely delivery for existing products remains a high priority, we also maintain our commitment to developing new design.

Wall Washing

True wall washing can be achieved with the use of ‘T’ lamp and linear fresnel lens. The linear fresnel lens is a concentrating optic, and is used in wall washing to redirect a significant portion of the light from ‘T’ lamps toward the lower portion of the wall. By compensating for the natural property of light to diminish in intensity the further the light must travel, the linear fresnel lens is used to achieve the smoothest field of illumination on vertical surfaces from a location on the ceiling relatively far from the wall. The formula for fresnel lens/’T’ lamp wall washing is 4:1. Example: To evenly wash a eight foot high wall, it is recommended that the linear fixture be positioned on the ceiling at least two feet away from the wall.

Wall washing provides a smooth, even field of illumination for vertical, flat, non-textured surfaces such as marble, where there is no surface texture to highlight or sheet rock where grazing would highlight the imperfections of installation. Wall washing is also perfect for art galleries where framed art is constantly changing.

Wall Grazing

True wall grazing requires that the continuous linear lighting equipment be installed in or on the ceiling or floor, with the flange or housing directly in contact with the wall, and the reflectorized spot lamps aiming straight down. While this creates a spectacular illuminative effect, more than half the available light does not strike the wall. To maximize the use of the available light, it is recommended that the linear grazer be positioned slightly off the wall to be illuminated, with the lamps aimed at a slight angle towards the wall.

Wall grazing provides dramatic illumination that reveals the texture of special materials such as brick, stone, stucco, glass block, fabric panels.

Wall grazing requires the intense beam of a reflectorized spot lamp, which has the optical power to reach the bottom half of the wall. Without the proper lenses, however, a row of reflectorized spot lamps will produce bright vertical streaks of light, which will only blend together at some distance away from the fixture. A special lens is needed here to blend the streaks together immediately upon exiting the fixture slot aperture. With this optic, the top of the field will be lit as evenly as the bottom of the field. This optic is known as a linear prismatic spread lens. Specialty Lighting Industries, Inc has developed a linear prismatic spread lens, known as Supertex, to achieve this preferred optic.
