Reviews

Used to replace the lenses on hard to find 1967 ford galaxie 500 rear pillar interior lights. Original lenses were all faded and yellow. Not a perfect fit of course, the originals had a thin edge to clip into place, but with these secured with some adhesive they look spot on.

Product arrived exactly as described, quickly and efficiently.

Item was exactly as advertised with quick delivery and well packaged

I purchased the 3mm and it was great as an insert to an otherwise very focussed bathroom spotlight, very pleased. Quick service too as always.

SGR used the opal discs to help diffuse some rgb led down lighters. We needed a balance of diffusion with the need to Colourwash the wall at the same time. The opal discs provided by simply plastics were perfect for the job. We received our discs very quickly after placing the order.

Product used to reduce light emission from overly bright LEDs - worked well

I had fitted two Led spot lights ether side of a sign. I had expected the spot lights to illuminate the whole sign on both sides. When powered up the lighten area was just in the centre of the sign and no use at all. I measured the diameter of the spot lights and ordered 5mm thick by 41mm diameter. When they were delivered two days later I couldn’t believe how good they were and defused the spots to cover the whole sign on both sides. I couldn’t recommend this company or product enough. I was very happy and impressed with the quality and service.

I recently built a small dressing area and rather than a conventional mirror with lights my wife wanted adjustable spots. We used some ikea white temp changing GU10s which work well but are very intense at close range. These 50mm x 3mm discs were perfect diffusers and have made all the difference. They spread the light well and remove the intensity of a direct LED. Perfect fit in-front of a GU10 and would not hesitate to buy again if I put spots in the ceiling as it gives a nicer appearance than clear glass with LEDs behind.

Light diffuser - superb quality and diameter exactly as ordered. Bought a light shade and added the diffuser to hide the bulb holder and bulb. Works perfectly and gives a classy light shade.

I bought these to cover an LED lamp that was shining right into my eyes. These softened the glare but still let the light through. Exactly what I needed.

I bought 3 acrylic discs, 3mm thick, and used them to diffuse the light from 3 single LED ceiling lights. The lights gave a very bright focussed light, but left much of the room in shadow. Adding the diffusers, which were drilled and countersunk, made a huge difference. The light is softer and far more pleasant, and no more shadow areas. They were very easy to fix with 3 screws each into the ceiling, leaving a small gap between the light and the disc to avoid any danger of overheating. Very pleased!

I used these diffusers to replace the one supplied as standard and the improvement was impressive. I wouldn't hesitate in recommending these products to anyone.

Very good and quick service thank you.

Excellent product and excellent customer service .. query was dealt with very promptly. Would use again and recommend to others.

Great quality product, used to diffuse two ceiling lights. Delivered promptly and fit perfectly. Very pleased and would definitely recommend.

Wanted to diffuse the LED lighting on my microscope for photography. I wanted softer white light to avoid bright spots on highly reflective small insects. Seems to work well without producing colour casts.

Superb White Opaque Disc. Precision Cut & Drilled. Rapid Delivery & well Packed!! Excellent Service! Used as a "Light Diffuser" Attached to a Vintage French Ceiling Lampshade of Opaline Glass with a Bronze Rim, beneath it to soften the bulb glare. Works Perfectly!!! Thank You

Ordered some diffusers for my living room and hallway lighting. Very quick delivery and in excellent quality with the exact measurement specified. Fitted my light shades with ease. Will definitely use Simply Plastics again for any future orders.

Bought two light diffusers. Cut to order. Worked perfectly to soften the light from LED spotlights and fit perfectly. Great service.

I used this to replace the diffuser base in a pendent lamp shade that got broken, It not only worked very well, but was actually better than the one it replaced.

Lens for reversing lights on a classic car. They proved to be ideal to diffuse the light.

Used on downlights to make them less dazzling. Worked well.

Great replacement for a broken glass lens, speed of delivery and service was outstanding. Many thanks.

Excellent interface for ordering. Product turned up in perfect condition - well wrapped. Overall, I was stunned at the quality, ease and service. Saved me buying a new light, after all.

Exactly what was needed to diffuse my kitchen lights

Used to diffuse the light from a 5 point LED light inside a stained glass display box. Worked perfectly, dispersing the light uniformly.

I used the product to restore an Art Deco style table lamp. One of those jobs I’ve been intending to do for some time. The lamp had a glass diffusion disk to create a silhouette and this had been broken. I found Simply Plastics during an online search for a replacement and thought the product would be an ideal replacement. Very easy ordering to size and although a service for hole drilling is available, I was confident I could drill the plastic which I did easily using a template. Excellent service and quick delivery of a well packaged product. I highly recommend Simply Plastics.

I used this to soften let ceiling inset spot lights, fixed the disc onto the led lens with double sided tape. works well.

Quick and prompt delivery, diffuser works great with my lamp and perfect fit

I needed to replace a cracked diffuser in a ceiling downlighter. The one I ordered was 3mm thick but the fitting needed a thinner one. However after sourcing some longer threaded screws I was able to re assemble the unit and the repair is fine.

excellent product ,speedy service

Used it to diffuse smart downlights within my bedroom to create a natural lighting effect.

Just as it 'says on the tin'

Used on some LED uplighters which were very bright when looked at directly. The diffusers are a perfect solution and arrived swiftly and carefully packaged.

Perfect fit

I brought these to reduce the glare on some existing colour changing led lamps in a gym I was sceptical at first but they were a perfect size and fit for MR16 fittings Very high quality and finish and speedy delivery , would certainly buy again Electrical Contracts Manager TEI Electrical

Unfortunately I managed to crack the Perspex diffuser that covered one of the lights in my motorhome. Finding simplyplastics online I thought it was a reasonable price and if it didn’t fit then not too much lost. I measured twice then had someone else to check. I uploaded my request and waited. Fingers crossed. EXCELLENT SERVICE. The diffuser is a perfect fit. Thank you

The led diffuser was perfect for my application. It was cut and drilled accurately and was delivered on time. I will be buying this product again, thank you
