Feit ElectricFC12/840/LED 32W Equivalent 20-Watt Non-Dimmable 2000 Lumen T9 4-pin G10Q Base Direct Replacement, 12" Diameter, 4100K (Cool White)

I have a kitchen light fixtures that burned out. I don't like the fluorescent bulbs so I took a chance these might work. These didn't require any alterations to the light, I do not do electrical so perfect. I installed both, flipped the switch and no light. I read that it may not work with every light fixture so I was bummed but figured I'd try one more time. One came on but not the other so I took them both out again and tried to get maybe the brighter or bigger of the two to come on. After a few more times taking them out both lights just came on and I've had no problems since then. There is a slight noise but it's not as loud as the fluorescent bulbs, no yellow flicker when turned on, brighter than the old bulbs. For anyone having trouble getting them to work, I would say keep trying a few times before giving up. My first two attempts were complete failures but it did end up working.

Easy plug and play installation. Unplugged old FC12 T9 fluorescent bulb. Plugged in new led replacement bulb. Initial impression is A+. This is for our kitchen ceiling fixture. The light produced duplicates the fluorescent it replaced in intensity, color, and light distribution around our kitchen. The added bonus is this led bulb is instant on. There is no 2-3 second delay as was the norm with the fluorescent tube. As far as energy savings or longevity I cannot comment as this bulb was just installed

Very happy with this purchase. I was hesitant to buy since some reviewers mentioned they don't fit right. Fortunately, these fit my fixture perfectly. Took just seconds to plug them in. They are brighter than the fluorescent bulbs. More importantly, they are more environmentally friendly and do not contain hazardous chemicals like the fluorescent bulbs. I'm sure everyone knows but just in case, do not throw your old fluorescent bulbs in the trash. They are hazardous waste and can be recycled at HD or Lowes. These bulbs they have a 5 year warranty - see photo for warranty details on box.

Typically, I prefer to use ballast bypass LEDs when converting from fluorescent. In this case, I didn't want to have to "dig" into the fixture, so I just went with this type. Super easy... plug, clip, turn on.Perfect replacement... same light color family but perhaps 25% brighter.I can't speak to dimmability; our fixture is on a simple single pole switch.

This bulb have great illumination, my room now have a sun inside.

Put them in a month ago. Still going strong.

Easy to install. Worked great for a minimally used hallway. 3 months no issues. Then a week ago both bulbs start making a clicking noise and then turn off. I brought a 12 and an 8(both round) 3 months is not the shelf life of an LED. Cheap internal components. STAY AWAY!!!!! Of course the 30 day window is closed. Buyer beware.

Great replacement for a fluorescent. Works with current ballast.Almost too bright but it says it will work with a dimmer.Will keep you posted and update after dimmer is installed.

Easy to install, better for environment, long lasting, nothing to dislike.

Light temperature is certainly pleasant for my home office, and is brighter than the dimming florescent (as shown in photo without diffuser), but I would buy an even brighter LED bulb if it were available.

They should come with it's own harness and clips. Tried first one didn't work sent back got second one didn't work. Really frustrated with the time wasted.
