Keystone Technologies Logo

Keystone Technologies was founded more than 70 years ago by Marvin Spielman and Harold Fox, brothers-in-law returning home from World War II. Fluorescent lighting was just becoming a popular, energy-efficient alternative to incandescent, so the two budding entrepreneurs formed Keystone at A and Cortlandt Streets in Philadelphia with a singular focus on manufacturing ballasts and transformers. With the advent of LED technology, we expanded our product offer beyond ballasts to include LED drivers. Now in our third generation of family leadership, Keystone is focused on the future, and continues to evolve with the changing demands of the lighting business.
