About CDL

Creative Designs in Lighting was established in 1978 by Walter Spitz. Walter gained a vast knowledge of lighting products through employment at a large lighting showroom. He then developed a “theatrical eye” by designing for the stage, including stage productions, musicals and dance. This knowledge, combined with a growing fascination in lighting, led him to study at Banff Center of Fine Arts under Laszio Funtek. Walter is an award-winning lighting designer, recognized across the country as a residential lighting expert. He is known for his ability to create warmth and intimacy through lighting and has a flair for drama and richness in detail. He has designed commercial and residential projects throughout the United States and abroad.
