Diffuser Specialist is a nationwide master distributor and manufacturer of ceiling light covers, lenses, light diffusers, and plastic lighting accessories. We stock a wide range of products from simple prismatic acrylic sheet to the latest in energy-efficient retrofitting technology – and to put it in laymen’s terms, that means we have a perfect light cover for all of your needs, functional & aesthetic.

Our friendly and knowledgeable staff can help you find exactly what you need and, if we don’t stock it, we can manufacture it to your exact specification.

As an already successful representative for Republic Conduit, Don Griffin was always looking for a new line to which he could apply his sales expertise. Don was immersed in the electrical industry and noticed a need for replacement lenses, ceiling light covers, and lay-ins of all kinds. Diffuser Specialist was started in 1982 by Mary Ann and Don Griffin with the philosophy that it is always cheaper to replace the lens than replace the entire fixture. With very loyal customers, Diffuser Specialist quickly grew into South Texas’ primary source of diffusing materials and accessories.

The ’90s brought rapid growth as Diffuser Specialist expanded their product lines. As the business grew, Mary Ann found herself taking a larger role in the company and became CEO.  Our large warehouses and family-owned hospitality make us the number one choice for all your plastic diffuser and electrical supply needs.
