Cooper Lighting announces a call for entries for its 31st annual SOURCE Awards national lighting design competition. The competition, which focuses on furthering the understanding, knowledge and function of lighting as a primary element in design, is open to all lighting designers, architects, engineers, professional designers, and consultants who use Cooper Lighting fixtures in an interior or exterior design project. Students currently enrolled in any of these disciplines are also eligible to enter projects based on conceptual lighting designs. Projects will be judged on the blending of aesthetics, creative achievement, and technical performance and to the degree which the lighting met project constraints and design concept goals. Entries must be postmarked by January 1, 2008. For more information or to request a complete list of rules, visit www.cooperlighting.com.
