U.S.-based
Dedicated to Light Made Easy since our founding in 1945.
For Keystone, lighting is more than great products. It’s also about great service – making it easy for our customers and partners every step of the way, from manufacturing and ordering to shipping and installation. It’s our mission to change the way people think about lighting.
A history of invention—and reinvention
Keystone started in 1945 when two WWII veterans saw a need in the growing lighting industry for fluorescent power supplies and ballasts. Since then, we’ve expanded and anticipated, becoming an OEM supplier, introducing ballast bypass LED tubes, and adding product lines to serve the industry.
Outstanding customer service
Service is at the heart of what we do. If you need a quote, we get it for you as fast as possible. We ship almost every product out the same day we get the order. We provide free samples of everything—if you want to try out one of our products, just ask. We have the best warranty in the business. And your tech support calls are taken by real, live humans.
Guaranteed performance
As a full-scale manufacturer, we offer the highest-quality products. Every Keystone fixture includes a Keystone power supply, so we offer guaranteed performance. Our products are 100% end-of-line tested. Our defect rate is less than 0.1%. We take pride in our quality and the unique designs that make our products easy to install, use, and maintain.
Innovative solutions
We think of ourselves as a 75-year-old startup. That means we’re always creating innovative, groundbreaking solutions, like adding features to common products — such as selectable power outputs and color temperatures — to reduce SKUs and improve end-user experience. Or creating a tool-free way to install lens optics, to simplify specification and field installation. Or designing architectural-grade fixtures with built-in versatility and convenience, making them easy to specify and easy to install.
It’s not just about lighting. It’s about improving the lighting experience.
Your one-stop shop
We know you value convenience and efficiency, so make Keystone your one-stop shop for all your lighting needs. You’ll find the latest in LED lamps, fixtures, power supplies, and controls. Need a custom solution? We can design and produce to your specifications. Whatever you need, you can count on Keystone.

We pledge to ship most items the very same day you place your order. Our 14 distribution centers are strategically located across the United States. Need it even faster? Same-day pickup is available.
