GE 97589 - F13DBX23/841/ECO - 13 Watt Quad Tube Compact Fluorescent Light Bulb, 2 Pin, 4100K

This light bulb last's many months in an outside lamp. Good purchase.

Works well; replacement for similar bulb. Too soon to reply on "Longevity".

These are the hard to find correct bulbs for our light fixture in the pantry. Bad news is that they are not as bright as we would like. When these bulbs burn out, we'll probably just switch out the fixture with a LED unit. These rest of the house has been converted to LED lights...haven't changed a bulb for over 4 years since changing every fixture out.

Great replacement light for bathroom fans. We use this as a night light when you only need a little light while using the restroom. Super easy to install. Yes it does flicker 1-2 times but so did the original one that came with the fan so not a deal breaker. You will pay 2x more at your local B&M

These work to replace the odd bulbs we have in our ceiling, but they flicker a few times before the turn on.

These I ordered 2 and it takes a few seconds for the second one to come to full light but it works for me

OK bulb, it flickers at startup ( unlike the OEM Panasonic one) but works

Sure they fit the Panasonic fitting and they work. But they pop a few times before they ignite and they buzz slightly. The original Panasonic bulbs did neither. But I don't see where Panasonic still sells these bulbs. So for now this appears to be the next best solution to replacing the bathroom light/fan.

very difficult to tell from the picture, but the pins are not opposite
