OUTDOOR SITE LIGHTING
Exterior site lighting provides the first impression of an automotive dealership and is an outward expression of image. During daytime hours, the form of the exterior site light should compliment dealership architecture and tie to dealership branding. For evening operation, properly designed site lighting entices customers, attracting business to the dealership. When developing site lighting configurations careful consideration should be given to surrounding establishments, the image you would like to portray to customers and the impact the lighting system will have on operating costs.
CONSIDER YOUR LOCATION
When selecting the proper light levels for your next dealership project, first determine how much visual competition is created by adjoining properties. The human eye is drawn to the brightest area in its field of view. In order to capture consumer attention, site lighting illuminance levels should be at least comparable with that of neighboring establishments without being

The Illuminating Engineering Society of North America [IESNA] characterizes surrounding ambient environments as high, medium or low competition areas. Based on this competition level, an average maintained illuminance target and a maximum allowable uniformity level are recommended for each section of an automotive dealership.

Exterior lighting requirements continue to grow more stringent. Many states and municipalities have adopted legislation that impacts lighting design applications. For areas requiring dark sky friendly solutions, full cutoff flat glass optical assemblies provide focused illumination with zero uplight and minimal high angle light while retaining superior uniformity. When strict spill light control is mandated,
