Let’s face it. Given lighting’s rapid transition to LED technologies, understanding all the dramatic advances can be daunting, to say the least. That’s where OHG helps…

We represent leading-edge manufacturers of lighting products and related controls technologies, and have been doing so in East Tennessee since 1990. From Knoxville’s Cumberland Avenue streetscape to Chattanooga’s Chickamauga Dam roadway you’ll find OHG-provided lighting products.

Our singular skill in delivering ‘real-life’ results of lighting’s performance and the infinite possibilities of color in the built environment, makes us unique in the region.
