4 Pack LED Troffer 2x4 FT Retrofit Kit,Magnetic Retrofit kit,36W (240W Equiv),5000K Daylight White,0-10V LED Driver/2 Tubes Per Kit,T8 T10 T12 Fluorescent Replacement Light Bar,Easy to Install

Super easy install, great lumen output, no hum or noise. Fit well in a 2ft x 4ft troffer fixture.

Once you remove the existing ballast installation is easy. Connect the black and white wires for power, everything else is easy. All of the led tubes and power box attach to the light fixture magnetically. Output are nice, bright led lights. Nicely made.

It was so easy to install the magnetic strips on the lights Made it a breeze less than 15 minutes from start to finish the lights are bright .The lights are very bright more so than the fluorescent bulbs that were in before. It came well packaged small box within a bigger box from Amazon

Positives: Easy install...ballast adheres to existing fixture and light strips plug in easily. Super bright once installed.Cons: Out of4 lights installed. 3 had one strip that dropped down from the fixture onto the lens. The magnetic strip stayed put, but the actual led strip dropped down. I used a bit of latex caulk to attache to back of strip and re-attach and that has been holding. since i did that another one dropped (not one that fixed) so did the same. Still you shouldn't have to do this and seems like a defect.Other con as noted in some other reviews one of my units arrived with no ballast. which was annoying...am returning that one and having replacement shipped. One other nit, the dimmable cables should really be capped if not used, and there's nothing in instructions saying to do that, and the power leads coming off the ballast are not stripped sufficiently (too short) so you need to strip a bit more insulation off before attaching them to power and wire nut.If they could address these two items I'd give 5 stars as lights are super bright and rest of install was easy.Update, vendor shipped new unit with ballast, and I believe first one missing was an issue with box being damaged un shipping. Tube light version also had strong round magnets as opposed to mag tape abd they are holding with no problems

The instructions are very easy to follow and took only a short time to install. It emits even nicer light than the fluorescent bulbs this replaced. Just one caveat, if you're not skilled or comfortable installing electric fixtures, this may not be for you. This is my 5th retrofit using either 2 or 4 magnetized LED strips, so I am sold on the energy savings and improved lighting these LED strips provide.

Took me longer to move the table, open the fixture, than it did to install the conversion. Required no tools and very little time to swap over to the new setup. No more bad ballast. Now I just flip the switch, and there is light. Now thinking about other projects this can be used on.

OK, so I'm not normally the one to write back reviews and i do give people the benefit of the doubt. I ordered these lights because of the dimming capability. I read all the reviews, and questions about them. I saw that they had problems with packaging, broken lights, going out in the middle and other things but i bought them. I ordered 2 of the 4 strip LED lights. I ordered them at the same time in one order.The orders were shipped separately. Once received, one box was 2in x2in square and just over 4ft long. It had look like it had been in a boxing match. In the middle, the box was taped together because it appeared to have been cut in half at one point and you could hear the strips inside. The second box was 8in x 8in square. Inside of it was a box just like the first box but looked brand new. The smaller box was just rattling around inside the big box.Upon opening the first small beat up box, the strips fell out. There was nothing but the lights. No wire nuts, or instructions. We opened up the second small box. They seemed brand new. The strips were in foam shadowing, and wire nuts in a baggie. The manual was shredded though and was no more detailed then the pictures on the product description. They said, turn lights off, remove cover, remove lights, remove ballast, install lights, install their ballast, reinstall cover and turn on lights. When we removed the LED strips out of the newer looking box on of the LED strips was not connected, in fact the connector fell onto the floor (see picture).After fiddling with this thinking i could snap it back into place, i realized it wasn't worth it. I returned both LED orders. So word of caution, i would seriously reconsider ordering from here. Hope this helps everyone in the future.

I never take the time to write a product review even though I have bought plenty of things on Amazon that I liked. But this product I just had to say some thing about. I have a rental house and the kitchen fixture had a bad ballast and the old fluorescent bulbs. I jumped on Amazon to see what there was for retro fit kits and found these. The magnetic tabs on them make mounting them super easy and it was literally a two wire hook up. These two small bulbs were brighter than the four fluorescent bulbs that were in this unit. No harm, installation couldn’t be any simpler. Amazing product. If you need to retrofit a fluorescent fixture, don’t hesitate to buy these. The only drawback I can think of, and it’s not really a drawback, is when you flick the light switch there is a half a second delay until when the lights turn on. But that’s the only thing I can nitpick. Wouldn’t hesitate to buy these again. I’m considering buying them for other fixtures that I don’t even have an issue with because they are so much brighter
