Keystone Technologies

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. At the time, several of the lighting industry's key fixture manufacturers called Philadelphia home: Keystone Lighting, Simkar, Crescent Lighting, Progress Lighting, and Sea Gull Lighting. Keystone quickly became a strategic supplier for their ballast and transformer needs.
