Beam Lighting Under Cabinet Light Cover Replacement | White Ribbed Acrylic Diffuser (L-Shaped, 33")

This came very close to perfectly fitting a legacy 18 inch fluorescent under cabinet light. The ballast went out, no replacement could be ordered. I acquired a 24 inch LED light strip, stripped off the ends, peeled the adhesive back and applied 18” against the light’s metal frame, trimmed off the last 6” and wired it into the Romex home wiring ends. As I mentioned it was a close but not a perfect fit. To avoid a ton of purchases and returns of other similar light diffusers, I applied double sided adhesive tape (3x 1/4 inch pieces against the light’s outer metal frame; and to attach the inner diffuser edge against the frame. The diffuser now easily removes, reinstalls and it stays in place! QUALITY: solid FUNCTION: easy to install, even close fits can work out with minor imagination! The diffuser allowed the light through without dimming it too much FIT: VERY close to original PRICE: Reasonable

I've been looking for under the cabinet fluorescent light covers for years. Nowhere has them and everyone that I can find is either too short doesn't fit or made of crappy material. These came delivered in a short time in perfect condition the plastic looks great they look like they would have originally out of the box in 1960 with these ballasts. I could not be happier with the outcome and I will be buying these again if ever anything were to happen to them.

The cover fit perfectly. It was a little tricky installing it. I would order from this company again.

Seems a little expensive for what it is - but it was a perfect replacement for the broken cover.

I needed to warm it up in the sun for awhile to make it slightly more pliable. Then it fit perfectly. As advertised.

While slightly more expensive than I originally thought I'd have to spend for replacement lens for my original yellowing undercabinet fluorescent light fixtures in my kitchen, these lens from Coolerguys are actually reasonably priced vs their competitors across the internet. With free Amazon Prime shipping, I decided to give their product a try by order one initial lens replacement. This initial lens was unfortunately crushed and broken during transit but Coolerguys promptly sent a free replacement lens. Once received, the lens replacement was easy to install and an exact fit. Based on this success, I ordered replacement lens for the balance of my yellowing lens. All were received safe & sound and are now installed. I separately bought LED light bulbs to replace my fluorescent bulbs so I now have essentially brand new undercabinet lights to refresh my eighteen year old undercabinet lighting. Thanks Coolerguys for making a high quality exact-fitting nitch lens replacement product that was perfect for my specific need. Order with confidence from this Seller!

Online it looked like it exactly what I needed . . . but in reality it's depth measurement was too big . . . so I will be returning it. More online information would have saved both the vendor and me the costumer this extra effort.

I am very pleased with this purchase. Product photos and dimensions were accurate. The thickness overall, including the ribbing and molded edges, all seem to be top quality. The cover was protectively sealed in clear plastic so I am confident it was a brand new item, not recycled. The only thing I noticed was that the specification details as shown on the Amazon listing showed the wrong length of 20", but the product title correctly showed 48" and the width, depth and curved shape of the cover were all correct, so I placed the order. I'm glad I did. It's perfect! I would have welcomed a bit of instruction either sent with the product or accessible from the product's listing page that shows exactly how to install the cover. A 48" cover is inherently somewhat unwieldy. It requires holding one edge in place and applying pressure to the other edge to pop it in place. It is not easy to do across the entire the 48" cover at once. I didn't know which edge to put in place first or where to start applying pressure or how hard to push. I didn't want to crack or break the cover by doing it incorrectly. I ended up going on YouTube to find a video of another under cabinet lighting installation that showed exactly how to pop a similar cover in place. I learned that the flat edge goes in first. Then, you have to hold the cover in place and apply just enough pressure along the shorter curved edge to push the lip into place so that the grove fits into the edge of the fixture. Tricky but doable. Once I knew exactly how to do it, I wasn't worried that I might break it. I was able to install the cover myself within a minute with just a few attempts.
