JESLED T8 LED 4FT Type A+B Light Bulbs, 24W(65W Equivalent), 3200LM, 6000K, Plug and Play or Ballast Bypass, 4 Foot LED Fluorescent Light Bulbs, ETL Listed, Single or Double End Powered, 4Pack

These LED tubes are great replacement bulbs for fluorescent fixtures that need either bulbs or ballasts since, once installed correctly, you will likely never have to replace them again in your lifetime (unless you're a teenager!). These are especially useful if your fluorescent ballast has gone bad, since a new ballast alone could cost you more than a couple of these new LED bulbs, and the ballast is completely disconnected and bypassed (I removed mine), thus eliminating the most "inefficient" device in your lighting fixture. Fluorescent lights were long considered to be the most energy-efficient lighting option available, and they were efficient--when compared to standard incandescent lights. But the ballast, which is necessary for fluorescent lights, is the most inefficient part of that lighting system and, although to a lesser extent than incandescent lighting, still converts a lot of electrical energy into unwanted heat. With the technological advances in these new LED tubes, you can toss those energy-wasting ballasts (which often go bad, themselves, requiring expensive replacement) and use your same fixtures with new LED technology that further reduces the energy lost to heat and much more efficiently converts electricity into just the light that you're wanting from a light source. Unless you're keeping small animals warm or trying to keep the dampness out of the inside of your piano, there's not much need for incandescent light bulbs anymore! These particular LED tubes are very bright, and possibly bright enough that you may find that you only need half as many of the LED "bulbs" installed as compared to your old fluorescent "bulbs"! (I replaced four fluorescent tubes in my laundry room with these LED tubes in the same fixture, and I had to remove three of the new tubes because it was way too bright! I have MORE than enough light with JUST ONE LED TUBE!!!) Also, unlike those old fluorescent lights which normally lost much of their brightness after a while, these LED lights will continue to maintain their light levels for years to come, all the while saving you small change day after day after day--and all those days add up to lots of dollars over the extremely long lifespan of these "bulbs"! BEFORE YOU ATTEMPT ANY OF THE FOLLOWING PROCEDURES, BE SURE YOU ARE KNOWLEDGEABLE ENOUGH AND CAPABLE OF WORKING WITH HOUSEHOLD WIRING! ELECTRICITY CAN BE DEADLY IF PROPER PROCEDURES ARE NOT FOLLOWED!!! Now for the technical stuff: These particular LED tubes are a direct replacement for old T-8 or T-12 fluorescent bulbs, and fit perfectly in standard sized fluorescent fixtures that have been MODIFIED INTERNALLY. While some LED fluorescent replacement tubes are designed to be used with a fluorescent ballast (why would you want to?), these LED "bulbs" are NOT designed to be used in fluorescent fixtures that still contain a ballast wired into the circuitry, and should NOT be used to directly replace fluorescent tube "bulbs" in an unmodified fluorescent light fixture! Before you begin installation, be sure to go to your electrical breaker box and turn off the circuit breaker that supplies the light fixture before you open the fixture housing. Then bypass the ballast (remove it from the circuit) or remove it completely from the fixture; the only things you will need to keep from your original light are the fixture itself and the "tombstones" (that hold the bulbs). If the existing wires inside the fixture are not long enough after removing the ballast, you may need to supply more wire to finish the job. ***FOLLOW THE WIRING DIAGRAM THAT COMES WITH THESE LIGHTS, because NOT ALL LED REPLACEMENT TUBES FOR FLUORESCENT FIXTURES ARE THE SAME!!!*** (Some are wired from just one end, but these are NOT THAT TYPE. Unfortunately, there seems to be no "standard" configuration established yet.) Also, the two contact pins on each end of these tubes are apparently not connected, so just because you have one service wire connected to each end "tombstone" (bulb retainer), unless your wires are connected to the proper side of each "tombstone" on each end, you may not close the circuit and the bulb may not light up--don't assume the bulb is faulty. I recommend that you remove the tombstones from the fixture (they usually just slide off) and temporarily wire them to an old power cord (don't plug it in until you're ready to test the wiring), then attach the tombstones to the new bulbs. After making sure all conducting parts (uninsulated wiring, etc.) are safely away from any conducting material (including flooring), plug the power cord into a wall outlet. If all the bulbs do not light up, unplug the power cord and reroute the tombstone wiring or use "jumpers" to supply electricity to the unpowered sides of the tombstones. Then plug the temporary power cord in and try again. Once all LED tubes light properly, be sure to secure the tombstone bulb clips into the fixture in the same correct orientation. DO NOT handle the disassembled fixture parts while the temporary power cord is still plugged into the electrical outlet! BE CAREFUL! Don't let fiddling with the light fixture's "tombstones" lead to you earning a tombstone of your own! ;)

Replaced our lights in our garage with these bulbs and they work great! Instantly turn on and are nice and bright.

I replaced the old fluorescent bulbs in the kitchen and utility rooms in my house and these bulbs were easy to install and much brighter than the old bulbs. So glad I used these.

These seem to be good quality and bright with good efficiency. By old florescent units can not handle them well and i have not yet tried to bypass the ballasts so they work for about 1/2hr then shut down until i let the ballast rest for a few min. so these arent a good drop-in easy replacement for all flor units but i was hoping. If I get time to bypass they may work better. When they are working they are brighter and whiter than flor bulbs were so for short times they are good!

Update: Feb 2025 Still working fine Update: 4 Years Later Still working fine. UPDATE: 3 Years Later Still working fine. UPDATE: 2 Years Later Sill working fine. UPDATE: 1 Year later Still working fine though to be honest, I probably don't have a ton of hours on them. Original One small room in my shop had two 4' fixtures that were barely working. Instead of new ballasts and conventional fluorescent bulbs, I decided to pop for these LED replacements. Install was very simple. On a 4' fixture the existing wires are generally long enough to not require a splice on one or both ends. Bulbs illuminate instantly and are a very bright, white light. They light up the room at least as good as new fluorescent bulbs would and probably a bit brighter but will cost almost half as much to operate and will last a very long time. (I have a reminder in my calendar to update this review in a year to comment on longevity) Packaging was better than expected. I am usually hesitant to order any kind of bulbs online but I think you would be hard pressed to find something comparable locally for the price. Each bulb was packaged in a thin cardboard sleeve, had a protective film over the clear lens and plastic protectors over the pins. These four sleeves were snugly enclosed in a thick hardboard [square] tube with a layer of foam on each end. This material is very rigid. The ends of the tube were capped with thick hardboard caps. It would have been a task for the USPS to damage this packaging. There is one caveat of using the LED replacement bulbs that I only noticed in this installation because of a very low ceiling in this room. Because the individual LED's are all mounted along a strip in the same orientation, the light is directed downward and therefor you do not get the reflection of light off of the top and sides of the fixture. This created just a little bit of shadowing on the highest portion of the walls. If the ceiling and lights were higher up, this effect would probably not even be noticed. I only noticed it because of the very low ceiling in this room (probably around 7-1/2'). When I reinstalled the diffuser panel it did negate some of this effect but not all. I do not consider this to be a negative aspect of the lights and would certainly buy them again for this room even if I knew about it ahead of time.

I would not recommend this product to anyone; I don’t know where they are getting these ratings? I recommend for Amazon USA at list not to permit to sell these products, until the vendor improves his quality inspection. He must device a system to test each light bulb to see if operates properly. Also, he must improve the packaging to prevent damage in transportation. He must include a detailed installation procedures in each bulb if sold individually or in a box if it’s sold in package form. This what happened and that is why I am writing this report/complaint, (by the way I hold Amazon responsible not the vendor becouse I purchased this from Amazon don’t know the vendor and the reason I purchased from Amazon I am hoping that what I get is in the standards that US customers are used to. I start the installation of this bulbs to my customers office (this is his only source of lighting in his office). I ask him to give an hour to install these bulbs and do the modification into the fixture. Proceed to remove the old ballast and connect all the wiring close the electrical trough in the fixture. This work did not take too long, after that I installed the first bulb and turn the switch on so I can see and not depend to my work light The bulb did not work I thought I did something wrong I open everything test the wiring and check the voltage and everything look good. I decided to bench test the bulb to fine out the bulb did not work. Then proceed to test all the other three bulbs to fine out that all three remain the bulbs worked. Proceed to install the three bulbs and ask some one to fine what was the procedure to replace the one bulb. As I was installing the three bulbs the first one, I got in my hand I realized the one side of the pins were loose after further inspection I found out the plastic base where the pins are attached was broking. Now I have two good bulbs left and I had to let the owner do his work I had to give him some light to work with. I install the two good bulbs so the owner can use his office. I took the broken bulb outside to the bench and with the help of a technician using super glue we glued the plastic that hold the pins. After half hour I was able to install the third bulb. And thank God I did that becouse I found out that Amazon would not replace one bulb only they need back all the four bulbs. I could not do that becouse the light fixture was already altered to except this LED bulbs that meant that this man could not use his office until we get the replacement bulbs and that was not acceptable. I proceed to trouble shoot the bead bulb to find out what was wrong with it. To my surprise I found the (+) and (-) wire coming from the electronics board were boking inside the insulation. After we replace the two wires the bulb worked. I proceed to install the bulb. A maximum 1-hour work turned to be 5-hour of work, with potential buying four more bulbs and returning these four more wastes of time. If the vendor did do his do diligent and test every single bulb, I would not have waits time and more to weighting this Complaint.

First thing I want to comment on is the packing these things arrived in. It was very impressive, the four tubes were in individual cardboard sleeves with tip protectors on each end as well as the ends of the sleeves are folded in such a way as to protect the ends and prevent movement. Then all four are snuggly packed into a dense cardboard, almost hardboard, like box that is sealed on each with a double layer of the stuff. Like I said, impressive. I live in a basement suite with almost no windows. A while back I decided I needed something else living in my space besides me, and since I’m allergic to most animal hair that left plants. As plants require light I did as I’ve done in the past I set up fluorescents. So far so good, except that most the bulbs I have are at least a couple years old and need replacing. So while I was looking around, doing some research I came across these lights and decided to give them a try for a couple of reasons. Now most fluorescents produce between 2400-2600 lumens per 4’ tube when new then go downhill from there. These LED lights start at 3000 lumens and my understanding of LEDs is that by the end of their life, they should be producing about 80% or 2400 lumens, in other words the same as a new fluorescent bulb. So firstly their longevity and sustainability and second was the cost savings, both in terms of buying bulbs and the cost of operating them. I have had them up and running now for five days and my plants are already responding very well. I’ll update this review in a month or so about how these are performing. Oh, and the light from these is bright and energizing but not overpowering, if that makes sense? One last thing I really like is the length of their rated life, 50,000 hours. Just to keep it in perspective that’s 5.7 years if you leave them on 24/7, for me having them on 14 hrs a day it’s almost 10 years. Take that and couple it with the lower power cost so that over a 10 year period I’ll have 30% reduction in power used or I can have 40% more lights for the same power. Gotta like that...going to need more plants!

I had to read the instructions twice but once I got it, it very easy to convert the fixtures to LED. They are much brighter than the flourescent bulbs. I put one in an unheated garage and they light up in the winter with no problem, unlike the fluorescent bulbs that struggled to come on in the cold.
