(Pack of 4) LED Direct Replacement F8T5/CW - T5 - 5 Watt - 12" - 500 Lumens - Super Long Life Light Bulbs - by KOR (Cool White (4100K))

Just installed. Bright, great update to what we had. But- like others have mentioned, these fit abnormally tight. The prongs on one were slightly bent in the fixture trying to get them in. You have to almost push your fittings apart to get the bulbs in properly. Aside from that, they do look great. Just ordered one more pack to replace two more bulbs. Picture added of old bulb vs new bulb brightness.

I originally purchased these a year ago. Thought I would try them out in a couple of the under-cabinet light fixtures for my kitchen countertops. They're a nice warm light, slightly brighter than my old fluorescents. And the best part, they last a long time! The fluorescents would last about two months, and they're on only about 5 hours per day. After six months, I bought more of these to fill the remaining fixtures! None of them have gone bad yet.

Bulbs put out a crisp white illumination. No more yellowish color like the ones I replaced. Come in a 4 pack and one bulb had a crack at the end. Took picture and called Amazon and said they would expedite a replacement. Replacement was here in a matter of days. Excellent customer service!

Two out of four bulbs in one of the package arrived broken

Great light bulbs. They work well. A+

The good: brightness and color are excellent. I bought over 2 dozen of these to replace under-counter fluorescents that were a constant nuisance to replace and only one has failed prematurely. It should be zero but still pretty good. The bad: The photos are of the bulb that failed prematurely. There is a yellow-brown residue inside the tube. I never smelled smoke or something overheating but from the appearance, I wonder if there might have been a problem of that kind. These bulbs were difficult to install. The fit was abnormally tight. I had to pry the fixture sockets a bit further apart to get some of them in. Much harder than with the original fluorescents but they did eventually go in.

Aweome direct replacements for the flickering flourescents easy to put in and no ballast bypass necessary at tall. Even considering our son is an electrician haha...... Worht the extra money.

Nice replacement for fluorescent but sometimes oscillates.
