## Customer Reviews

### ⭐⭐⭐⭐⭐ Worked perfectly
*by J***E on June 18, 2025*

I needed to replace one that I previously bought on here three years ago. The quality is great and it was very easy to put in. For me this is a great value as they are hard to find. I got it yesterday and it was shipped very fast. Works just as intended, no flickering at all.

### ⭐⭐⭐⭐⭐ Replaced light bulbs in Panasonic bathroom fixtures
*by D***N on March 30, 2025*

We have a Panasonic ceiling mounted bathroom light/night light/ fan/heater. This odd shaped light bulb is the correct replacement for the main light. It gives a soft yellow light, no modern wavelength adjustments.

### ⭐⭐⭐⭐⭐ Quality fluorescent lamps, nice color
*by J***N on December 21, 2023*

These lamps are a perfect fit in our Panasonic Light/Heater/Exhaust Fan ceiling mounted unit.The 3500K model provides a nice natural slightly warm light without being too yellow. Please be aware that there are many specifications of these lights. Check your original lamp for model number, number of pins and overall wattage before purchasing.
