Over 40 years ago, Bill and Dolores Kreitsek opened Suffolk Designer Lighting ("SDL") in Riverhead, New York. At that time, SDL catered mainly to local electricians and homeowners. In 1974, SDL moved to a new facility on East Main Street in Riverhead. While on East Main Street, SDL grew its electrical and lighting business, selling to a wide array of customers on both Forks of Long Island and Western Suffolk County. In 1985, SDL opened its store in Southampton, the location where SDL still operates. Over the past 23 years, SDL has continued to grow, but remains a closely held family business that emphasizes its relationships with its customers.

Today, the business serves the entire East Coast from its home in Southampton. SDL stocks hundreds of fixtures from more than 450 manufacturers in renovated 8000 square foot showroom. In addition, SDL carries various home accessories to supplement our customers' lighting needs. SDL's knowledgeable staff works closely with architects, designers, decorators, builders and electricians to meet all of our customers' needs. SDL specializes in high end custom homes, restaurants, and country clubs. Our consultants have over 100 years of experience, bringing you the best in layout design for both interior and exterior spaces of any kind.
