Every Commercial Project begins with a simple concept derived from functionality: for what purpose will the tenant or owner use this new or renovated building? The answer to this simple question provides the foundation for the project and determines the form and function of all the components of the project, most especially the lighting design. With functionality known, many of the thousands of lighting options can be eliminated allowing the designer, architect, contractor, or specifier to focus on only the options that will provide the styles and functions needed for the project. A Linear Fluorescent Troffer may be the perfect lighting option for a ceiling application in an office building, but may not provide the necessary lighting output needed in a large warehouse.
