KEYSTONE TECHNOLOGIES, LLC

It Began with Ballasts…

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.

And Evolved to Drivers…

With the advent of LED technology, we expanded our product offer beyond ballasts to include LED drivers. This was a natural transition for the company as drivers are similar in role and design to ballasts. Keystone was able to apply years of expertise in ballast manufacturing to quickly develop high quality drivers for a wide variety of applications.

And then to LED Modules and Light Engines…

Keystone’s business grew significantly along with the demand for LED drivers. It was not a big leap to start producing our own modules and Light Engines, which gave us the ability to customize complete LED systems to meet individual customer demands. Keystone has become a primary supplier for a variety of OEM accounts, who have diverse needs and product requirements.

LED Boards lead to LED Tubes

It wasn’t too long before a Keystone engineer slipped an LED board into a tube and Keystone’s LED lamp business was born. Keystone saw immediate success with both SmartDrive (plug & play) and DirectDrive (ballast bypass) technologies. We have established ourselves as a leading resource for an ever-growing list of LED lamp types including linear, compact and HID. LED products represent the fastest growing segment of our business and we are striving each day to bring you the latest in LED lamp technology.

What’s Next?

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. As our company experiences unprecedented growth, we pursue a path of leadership and quality, and remain committed to the legacy of truly personal service established when Marvin and Harold made their first sale in 1945.
