F8T5/CW T5 LED Tube Light Bulbs, 12-Inch, 5W, 500 Lumens, 4-Pack

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!

WARNING I removed the 2 working fluro tubes and inserted 1 LED replacement. Turned power on and LED replacement shone brightly. After a few seconds, turned power off and installed 2nd LED. Turned power back on and no light then smoke came out of the fitting. Replaced the once working fluros but no joy. The fitting was burnt out. Thinking I may have received a faulty LED replacement, I removed the 2 fluros from another working light and installed a different 1 of the 4 LED replacements I had bought.. When turned on, the light shone brightly for about 10 seconds before the light went out and smoke came out of the light fittings. So I have destroyed 2 working fluros. I have 7 double fluro light fitting in my RV so will need to find a different solution.

Great replacement for standard tubes

Lights work fine but was disappointed one arrived broken

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.

We like the LED under the counter light bulbs because they last so much longer than the fluorescent bulbs.

All of the units I bought developed a humming noise after a couple of months, which (as many studies show) is unhealthy in addition to being annoying. They will end in trash, as soon as I can find a replacement product. Shame, humming lights should be a thing of the past, especially with the LED technology being widespread (and in my household, noise-free other than these).

I purchased these as direct replacements for existing fluro tubes in NARVA P/N 87430 ceiling light. After switching on, the lights briefly illuminated before turning off. When I replaced the old fluro tubes, they no longer work which leads me to believe the LED tubes have also blown the ballast circuit. I now have no working campervan ceiling lights. I ordered a replacement set of tubes and did a bit of experimenting with them before installing. I've now come to realise that they are NOT compatible with DC power, regardless of ballast type. Have returned them and ordered LED tubes that are specifically designed for 12V DC.
