JESLED T8 LED Type A+B Tube Light 3FT, 2520LM, 18W(45W Equivalent), 6000K, Plug and Play or Ballast Bypass, 36 Inch F30T12 Fluorescent Bulb Replacement, Dual Ended, 36” Lighting Tube Fixture (4-Pack)

This was my experience replacing the light tube in my 24" 20Watt aquarium fluorescent light. I chose the 6000K color temperature of this replacement to simulate the full sunlight spectrum. Unlike other "daylight" lamps, this particular light is not excessively blue or purplish in color. I also expected the brightness level to be higher than that of aquarium specific lamps.My aquarium light hood was originally manufactured with a ballast and a starter. This was a common method of wiring these fluorescent light hoods. The inclusion of an automatic starter device, instead of the push-to-light switch, allowed the use of a timer to control the lights. I had already replaced the FL tube with an LED type. The original replacement unit did not require that the ballast be removed, just the starter. This time around, I bit the bullet and decided to try this type of LED replacement tube. There are three basic types of LED replacement tubes. Besides the ones that do not require the removal of the ballast, there two types that involve a wiring modification. One kind of replacement LED lamp is powered from just the two pins on one end of the tube. This may require the replacement of the actual sockets on the fixture, and I felt this would involve additional work and wiring. I also did not like that the light tube has to then be inserted in a specific orientation for it to work.The other type is what it is represented here. The lamp is powered by running one wire from the AC to each socket. Removing the ballast and the starter from the circuit was a rather simple modification. The existing switch and socket wiring was long enough to connect to each of the lamp and no additional parts were required. I went ahead and also removed the socket for the original starter and, since the fixture is subject to moisture, I sealed all of the access and mounting holes leading to the exterior. The light was never meant to be waterproof, but I didn't want any water accidentally spilled on it, to have a direct path to the circuitry inside.Ok so, how did it work out? The tube lit right up without any flickering or vibration (hum?) noise. My aquarium is 24" inches high. The light is bright enough to properly illuminate the substrate. It works very well for my application. I would certainly recommend it for this or any other application where you can make the necessary modifications to the fixture.

I'm so happy I switched out the kitchen fluorescent lights to these LED lights. I researched whether they would fit in the current kitchen sockets and they did. I watched DIY videos to convert fluorescent to LED, but opted to hire an electrician to make the switch. It took him less than a half hour to install 8 new lights and switch the ballast. Light is VERY bright, which I'm fine with in the kitchen. I wish they were dimmable, but that may have more to do with my electirical system set-up. Very pleased with this purchase. Good value. I can't speak to longevity because they've only been up a couple months. But supposedly, the LED life span is similar to fluorescents, which lasted nearly 10 years.

These bulbs have been in for a few days and are working great-very bright. I used these bulbs for a fixture that had a ballast bypass done. One thing to know is that these bulbs are dual ended, meaning they have prongs that are energized from the tombstones on both sides of the fixture. At first, I mistakenly bought bulbs that were single sided, meaning they were energized by tombstones on one end of the fixture.

I plugged these into two different fixtures, each of which had two old but functional fluorescent tubes. These tubes would rarely light up, and if so, only after considerable delay. Sometimes they lit up and later turned off on their own accord. I have gone through numerous tests: leaving them on for some time to burn them in, if they deigned to start. That didn't help. I put them through on-off tests -- that didn't help, either. Perhaps I could remove the ballast and get them working, but that should not be required.Some years ago I bought some other LED tubes, but they were four-foot tubes, and they have worked perfectly every night.

Please like this review so other buyers see it.This is a frequently returned item because the only instructions that I saw were in the one picture on here. Nothing comes in the box.So the first thing you can do is just take your fluorescent bulb out and put this one in. It'll probably work just like that. But that's not ideal because the ballast will still be making the humming sound. So it's super simple just to unscrew the ballast and cut all the wires.You will have a white and black wire coming from the ceiling, and then I had two red wires going to one side of the bulb and two blue wires going to the other. I'm not sure it matters but I assumed that the red was positive and the blue was negative. So I hope the black wire to the two blue wires and the white wire to the two red wires and it worked great without the humming. Please see attached pictures I hope this helps

Pretty easy to install. Made big difference in the lighting in our kitchen.

Worked for replacing my old bulbs.Instructions were excellent.Package very nice and protective.Thank you
