    Highly Recommend Diffuser Specialist

    We could not find any manufactured safety covers that would work for our warehouse lights at Oats Overnight. Nick at Diffuser Specialist designed custom light shields based on our rough measurements and some poor quality photos. Their turnaround was fast, their price very reasonable, but I was most amazed that when they arrived, they all fit like a glove as if Nick had been here measuring the lights himself.

    Great job Nick! I highly recommend Diffuser Specialist, their service, quality and value are all outstanding.

  • Perfect in fit, finish, and quality!

    To the team @ Diffuser Specialists,

    I received my diffuser’s today and I’m happy to report that they are “perfect” in fit, finish and quality. It saved me from having to replace the entire fixture with something new.

    I appreciate your expert help and customer service even though this was a relatively small job. I had searched a good bit and no one offered exactly what I was looking for.
