Did not fit

### ⭐⭐⭐⭐⭐ Fits perfectly
*by A***R on February 18, 2025*

Nice to find replacement Diffusers for our older lights

### ⭐ Does not fit or function
*by F***N on October 18, 2023*

This 4 ft cover has two end caps. You can't spread it to fit in a tight space. When I finally got it partially on, the end cap pressed hard on the two fluorescent bulbs. It can't be put on with bulbs ib the light fixture and you can't put in thebulbs after the cover is in place. Dummer than dirt design. How this is designed and engineered to work is totally incomprehensible. I broke it trying to install it. Surprisingly I did not brake either bulb. I can't return it but my money should be reimbursed.
