### ⭐⭐⭐⭐⭐ Terrific!
*by D***M on July 5, 2026*

### ⭐⭐⭐⭐⭐ Great fluorescent light replacement
*by L***S on July 30, 2026*

Fit and worked great. I love the switch that changes the light from soft white to 5000k bright.

### ⭐ Measurements not as represented
*by D***D on October 6, 2024*

I purchased this months ago. It seemed overly tight by 1/4-1/2 inches on the widths ordered. I struggled putting it on the light fixture and did not return it to Amazon because I feared I would break it. Soon after the light itself begin going off then on when the power was on. Turns out this was because the item was so tight it was crimping the fluorescent bulbs and vibration in the laundry room caused the light to fail. We put up with this for a few months and I finally removed this cover. The light works fine but I need a now light cover. It is my opinion that the manufacturer may have poor quality control. I will buy a replacement.
