Keystone Technologies - Light Made Easy - LED Solutions

FEATURED BRAND

Keystone Technologies was founded more than 75 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.
