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!

This bulb exceeded my expectations. I dislike cold, white fluorescent light, and wanted something warmer. This is it! Plugged it in, turned it on, and was amazed at the warmth and brightness it provides. Makes my kitchen area look so much better. Perfect for my needs.

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!

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.

I didn't want to go to the trouble of removing my old CFL tube fixture and wire in a new fixture, and I didn't want to remove the ballasts and stuff from my existing CFL fixture in order to add one of the more common LED tube fixtures, so I tried this Plug n Play LED tube and it works great! I just took the old CFL tube out and put this one in and it worked! Took all of 30 seconds. It's only been in use a couple of weeks but it is working great so far!

I should have returned the bulb but I was determined to install it. First thing--the bulb was actually "warped" slightly, like a crooked board. Rolling it on my table you could see a very slight bend in the tube. So that, OR the pins on each end were possibly too long, that caused me about a 1/2 hr of frustration but I finally got the bulb in. It did turn on but I was really disappointed in 4100 Kelvin brightness too. I was replacing a 2700 Kelvin LED lamp and I wanted more light in my tank, but the difference was hardly noticeable.PS. The 2700 K bulb EASILY slipped in and out of my light fixture, so there was something wrong with the new 4100 K bulb. I fought hard getting it in the fixture and didn't want the hassle of NOW trying to get it out for a return.

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.
