## Description

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

Review: WRONG SIZE - Very nice product but it was the wrong size so I had to return.
Review: Exact Replacement for my Yellowing UnderCabinet Light Fixtures! - 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 desertcart 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!

This part fits but it is a little bit stiffer than the one that it replaces. It would take a little bit of effort to install.
