Worked perfectly
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
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
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.

Excellent, but almost double the price of No Brand replacements!
Fit, Brightness, Color are as per the specifications. So all good! Cannot comment on longevity yet. I am Okay with paying up to 20% higher for Sylvania brand, but these are almost double the price of no brand! I am still keeping these! :-)

Excellent price and well package
My bathroom ceiling fan takes two of these compact fluorescent tubes, and both died at the same time. This vendor had exactly what I needed and at the best price I could find. The price included shipping, and the bulbs arrived in a perfectly reasonable time for a cross-country trip from NJ to CA. When I opened the box, I was particularly impressed with how well wrapped and fully protected the bulbs were. I would definitely order from the same vendor again.
