### ⭐⭐⭐⭐⭐ Works great.

Replacement lamps for kitchen lights. Works well.

### ⭐⭐⭐⭐⭐ Fluorescent light bulbs
*by C***R on August 28, 2025*

These bulbs were in perfect shape with each one in its own little round tube soft foam housing. I'm not sure what the deal was but they wouldn't work in my light fixture even though the numbers were the same. They fit andctwited in place, but didnt light when the switch was turned on. Unfortunately, I had to send back. Don't hesitate to try them though! My fixture is an old one so that might be the problem I'm having!
