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 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!

Part fit but a bit hard to install.
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.

works well if you measure correctly
Be sure of your measurements. I needed a replacement cover for an existing light fixture that had yellowed. Fits fine.

Too short
Bought 2. They are not 24 inches. Both measure 23 3/4 in. So, there is a gap. Don’t buy from this vendor

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

Doesn't fit anymore
I've ordered a diffuser cover before and it fit perfectly. The second one I ordered was slightly too wide so I couldn't push in the edge to hold the diffuser in place. Ended up chipping the corner a bit due to the force. For the price, I don't think these are worth it anymore.
