Since Founding more than 65 years ago by a veteran returning home from World War II, Keystone Technologies has grown into North America's leading independently owned ballast manufacturer. They serve the largest lighting fixture manufacturers in North America including full service, architectural, and specialty OEMs as well as thousands of local, regional, and national wholesale distributors. Keystone began manufacturing in a shop in North Philadelphia, but their operation now includes 15 well-stocked warehouses across the country.
