2 FT/ 24" Plug & Play LED Tube - Cool White (4100K) T8 LED Lamp Directly Relamp 17W 20W Fluorescent Bulb F17T8, F24”T8, F20T12 840 841 (Without rewiring or Modification) - Ballast Required!

These work. Just replace the old tubes you have with these. Nice and bright, correct color temperature, and easy. They stay nice and cool. No rewiring required. Read the instructions. You gotta have a ballast.

They came packed in their own cardboard box and each tube was individually wrapped inside the cardboard box, which came in a bigger, well packaged Amazon box. (I ordered two of these LED tubes.)These lights installed the same, exact way the fluorescent tubes did that they replaced. Line up the little pins on the ends of the tube to the little slots in the light fixture push in just a little bit and twist the tubes. You don't have to take out any ballasts or do any electrical work. Easy peasy, lemon squeezey!I had two 20 watt fluorescent tubes in the fixture in my bathroom. I took those out (which I have only had in for less than a year) and put these in. These bulbs use 10 watts each, so instead of 40 watts, I'm now spending 20 watts. The kicker is that these lights are MUCH brighter than the fluorescent bulbs that I removed, and the color of the things they cast light on have colors that are 'more accurate'. These tubes I purchased are the 6000k Daylight bulbs.Another plus is that these lights come on instantly. The fluorescents took about a half-second.I am very pleased with these lights and highly recommend them. I didn't think they were going to make such a huge difference in the brightness and color in the bathroom. I may go ahead replace my fluorescent tubes in the kitchen., too.

Installed this new LED light tube in range hood over the stove. Wife loves the bright white 6K daylight color for cooking. Light glows bright in all directions; would never guess there are LED light strips inside. The length of this model (approximately 24-inches) was about a quarter of an inch too long, requiring a bit of trimming using wire cutters to reduce about an eighth of an inch from the metal prongs on each end of the tube. After trim, installing into the range hood was plug-and-play. No need to worry about ballast or wiring.This light has two small metal prongs on each end to match fluorescent light fittings.Installed easily as a direct replacement for a Philips F20T12/CW 24-inch fluorescent light, after minor cutting the electrical points to allow the tube to slip into the existing fitting. No special tools necessary other than wire cutters or snips that can trim the length of the prongs.

I installed one of these in a basement sink fixture and then realized we haven't been using the light over our 1st floor sink, because it flickered forever, then settled on a booger-colored light. These are much brighter- LEDs are directional, so all the light comes out- it's not bouncing around so much inside the fixture- you get the stated lumens! Always replace the starter when you replace the bulb! If your ballast doesn't use a starter, then forget that part, but if you hook up any bulb in a fluorescent fixture without a new starter, you could be abusing your new bulbs. These bulbs are quiet. Now, I can hear the ballast, which I never heard before, because the old bulbs sang their own song. I don't notice any flicker. I bought the 5000k for good daylight color-rendering, and because I need accurate color to use my aquarium water test kits.I can't rate longevity except to say: these are LEDs designed to work with a ballast/starter. If your ballast/starter are working within spec (i.e. new starter or good ballast), then these bulbs should work for a very long time, as long as they don't get too hot or get banged around. I have no qualms about giving 5 stars for longevity, because these bulbs are in stationary fixtures, working perfectly, and I have no plans to do anything silly to see if I can break them. These are great bulbs!

Bought to replace a burned out Philips F20T12 bulb in the closet. I really wanted to swap to LED but without having to do any wiring. This bulb delivers!Super easy to just twist in. The diameter of the bulb seems smaller than the old one, but caused no issues. Length correct, pins slid right in. Turned it on in under 30 seconds, super pleased!I also believe it's brighter than the old bulb (which may have been dimming at its age). But apples to apples it puts off more light for sure.This is the cool white color (same as my old bulb).

I like this bulb. GREAT for a closet where the old fluorescent bulbs are dim and dark by comparison. Good light.However, why does Anything take 2 weeks to deliver in the Amazon era? 2 Weeks? I can get most things in Dallas the same day as of July 2020. Also, $5.99 to ship one bulb. It will likely last a long time, but $24 seems high for the total cost. Hence, 4 stars instead of 5. If you have 2 weeks to wait and $24 a bulb works for you--this is actually a great solution for the painful era of Fluorescent bulbs. They are the worst, most dangerous, most absurd development in lighting. (Yes, the house we just moved into has Fluorescent bulbs in every closet. So painful.) Each one has problems. So, kudos for this LED solution. That is all. Thanks for reading.

Easy install replacement for the T8 flourescent bulb and the light output was quite impressive. It failed to work on the 9th day so will be returned for a 2nd try. If that one also fails in such a short amount of time, I will add these to my do not buy list of Chinese junk.

The length is about 1/4" too long. Had to pry the sockets back just to fit the bulb in. What a PITA!!! If you manage to get it to fit, the light looks nice. But I will certainly never go through the struggle and pain to get these to fit again. It is NOT worth it! I would recommend another brand.
