St. Mary's Lighting and Electrical Supply, Inc. is proud to be the premiere supplier of electrical supplies, lighting fixtures, datacomm supplies, Klein Tools and Milwaukee Tool products in the Southern Maryland and surrounding areas. St. Mary’s Lighting was started in April of 1982 by Ralph and Alice Owens of Dameron Maryland.  Since the first day, Ralph and Alice have dedicated their time to providing top quality products at the lowest possible price to their customers.  For more than 20 years we have helped our local community light their homes and businesses as well as helped the local contractors grow their business as we grew ours.  Trust, honesty and a commitment to excellence has enabled our business to become a major contributor in aiding the rapid population growth of Southern Maryland.  

St. Mary's Lighting and Electrical Supply is continuing to implement new ideas to better serve our customers.  An online store is currently in the works and will enable our busy customers to view our products, check our inventory, and place their order without ever having to leave their office.
