We are dedicated to the mission that lighting should be simple,
hassle-free, and enjoyable: Light Made Easy.

Lighting is our reason for being. It’s all we’ve done since 1945,
developing energy-efficient lighting solutions for the industry’s
most discerning customers. From legacy fluorescent lighting
systems to the latest LED technologies, Keystone is singularly
focused on being your one-stop shop for high-quality
lighting products.
With over 100 million Keystone products in use today,
thousands of installers, architects, and engineers have come to
depend on Keystone for lighting products that are manufactured to
last. 100% of every production run is factory tested so you know
that when a Keystone product is installed, it’s made to perform.
