Feit Electric FC12/840/LED 32W Equivalent 20-Watt Non-Dimmable 2000 Lumen T9 4-pin G10Q Base Direct Replacement, 12" Diameter, 4100K (Cool White)

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

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.

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

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.

Nice light color, bright. Some fixtures will be clocked wrong on the plug and it will hit the fixture cover. Had to bend the mounts slightly.
