## Description

Beam Lighting Under Cabinet Light Cover Replacement | White Ribbed Acrylic Diffuser (Curved, 12") - desertcart.com

Review: Great option for retrofitting! - 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
Review: Light cover worked fine. - I needed to warm it up in the sun for awhile to make it slightly more pliable. Then it fit perfectly. As advertised.

### ⭐⭐⭐⭐⭐ Perfect fit! Fast delivery!
*by P***G on January 19, 2025*

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.
