Diffuser for light panel, they material was as spec and dud the job perfectly

I used it to replace a panel in my greenhouse I was very pleased with both the product and the service and would definitely recommend your company

I ordered to cover some exposed lighting. Very quick manufacture and delivery. Finish was excellent. Highly recommend both the company and the product.

Cut to size plastic, works fine.

Used as diffuser to cover flourescent tubes, excellent quality, could not have asked for more. Very reasonable price.

very good product

To replace the sheet in the industrial elight thatnI use and has over years turned yellow

I bought this product to glaze a door of 15 panels, I chose this over acrylic because it has some fire resistant properties. It has worked a treat and all panels fit perfectly. I am very impressed with the service and speed of delivery, very happy all round.

Opal light diffuser panels, order to exact sizes, competitavely priced, delivered in couple of working days, packaged very adequately therefore arrived safe and sound!! What’s not to like? Definitely would use again. Thank you simplyplastics

Used for diffusing LED lights above an aquarium. The piece ordered had to be cut to exact measurements in order to fit and was absolutely spot on.

Very good. Happy with product.

I needed to diffuse the intense light from a small fluorescent lamp in an alcove, by using Opal Polycarbonate sheet over the tube it has subdued the glare, while still allowing enough light to illuminate the alcove, as the fluorescent light produces almost no heat I was able to fit the diffuser close to the tube without problem.

I used it to defuse 2 1200mm LED lighting tubes for my aquarium, I drilled and fitted clips to the plastic and clipped them to the underside of the tubes, as with most LED lighting tubes they are not defused making the lighting rather harsh. They worked perfectly just what I wanted, and would certainly recommend, it is a problem aquarists are facing as LED lighting becomes more popular, mainly to cut electricity costs
