The luminaire industry holds untapped potential for engineering plastics as effective material alternatives to metals and glass. Unrealized savings in unit costs and energy consumption coupled with design freedom are afforded the innovative lighting engineers of today and tomorrow. As society demands more judicial use of limited material resources, the inherent advantages of polycarbonate and other thermoplastics will be increasingly called upon to solve fixture design and performance problems. The major beneficiary of these trends will be the final user, who will have useful, high performance, and aesthetic lighting devices available at the right price.
