Bringing It All To Light®

American Made

Design, engineering, manufacturing, fabrication, assembly, testing, customer service, shipping, billing... it all comes from the middle of America, out of our Chicago headquarters and manufacturing facility. Because we are joined by hallways not highways, we have total control over everything needed to supply high quality products, superior service, and fast delivery.

Engineering & Customization

Our vertically integrated operations allow us to create exceptional luminaires that stand the test of time and to provide superior service and support. Unlike some companies out there, we don’t just make lighting. We create lighting, turning what’s in your head into lighting that goes over it. Count on our team to help you customize our luminaires to deliver the lighting look, feel, and edge you want.
