JESLED4FT T8 LED Type B Tube Light Bulbs, 24W 5000K Daylight, 3000LM, 4 Foot T12 LED Replacement for Flourescent Fixtures, Frosted, Double Ended Power, Remove Ballast, Warehouse Shop Lights (25-Pack)

UPDATED 1/22/19After being so disappointed by the initial product delivery and leaving the negative review below on 1/18/19, I felt the need to update my feedback after dealing with JESLED customer service over the past few days.Amazon processed my return request for the 8 tubes the evening of 1/18/19, the next morning I received an email from JESLED (John Chiu) asking if the shipment I received was okay. I proceeded to explain that 7 of the 8 tubes were broken upon arrival and that I felt the packaging was inadequate. I also stated that I was even more upset because I already rewired the three two-bulb fixtures in my garage to utilize the LED tubes and now I was stuck without lights unless I re-installed the ballasts, which I was not going to do. John replied offering to send me a 12 pack of tubes at a 20% discount. I replied stating that I only needed six tubes, and was going to keep the original two extra as spares and that I was not comfortable purchasing these tubes again due to the 87.5% broken product rate of the first shipment. I couldn’t help but think the replacements would arrive broken as well. I also said that if they were willing to provide free replacements that were undamaged and operational that I would be willing to update the below review to reflect the company standing behind their products and willingness to ensure customer satisfaction. I did not expect JESLED to be willing to provide the free tubes, I figured the conversation was over at this point. I COULDN’T HAVE BEEN MORE WRONG!! On 1/20/19, John replied and stated that they were highly concerned with their customer’s experience and that the 8 replacement tubes were on their way! I received the replacement tubes on 1/21/19. Upon opening the packaging, I found that all 8 tubes were unbroken and appeared to be perfect working order. I proceeded to install all eight tubes to ensure they all worked and unfortunately, I found that two tubes were not operational. There is nothing obviously wrong with them, but they will not illuminate when energized. I even tried moving them to different fixtures to ensure there wasn’t something else causing the issue, but that didn’t help. I replied to John to let him know what I found with the new tubes. Today (1/22/19), John has stated he will send another 4 pack of tubes to replace the two faulty tubes. With the company being so willing to stand behind their product and provide replacements to ensure their customers are satisfied, I felt compelled to update my review to 5 stars. The tubes that work, work great! They are much, much brighter than the old fluorescent tubes, and the 5000K color is perfect for the garage! Also, these lights turn on instantly, zero delay at all! As a side note, right after requesting the initial return, I purchased Hyperikon tubes to replace these, not expecting to be contacted by JESLED. I can honestly say, in my opinion, these tubes are slightly brighter than the 5000K Hyperikon tubes and definitely turn on quicker. The Hyperikon tubes had a slight delay, maybe a second or less, but noticeable. For the sake of honesty, I will say the Hyperikon tubes “felt” a little more solid, like the materials were a slightly higher quality, but in my opinion, not enough to warrant the difference in price, especially considering the lag in turning on. I will be returning the Hyperikon tubes, in favor of the JESLED tubes. I also attached a picture of these tubes when lit, just for reference, keep in mind this picture was during the day and the garage was not dark due to the windows. I still think there may be room for improvement in quality assurance and packaging, but after the initial disappointment, I have to say the customer service and products are great! For the value, I would recommend giving JESLED a shot, and if something is wrong, don’t hesitate to reach out to their great customer service.Original Review - 1/17/19I ordered two sets of four (8 total) of these lights. Figured the reviews were great (even though there weren't a ton of reviews) and for the price they were worth a shot. I should have known better. The lights arrived in two packages, four in each. I opened the boxes and at first glance everything seemed good. I rewired the first light fixture and was ready to test out the new lights. When I went to remove the protective caps from the ends, I noticed the pins we're pushed into the fixture slightly. Turns out the plastic around the pins was broke. Looked at the rest and 3 of 4 lights were all broken on the same end in that shipment. Must have been dropped or something but the foam in the end of the box is completely inadequate to protect the overly thin plastic. I proceeded to open the second box and guess what... All four of those lights were broke in the same place. To summarize, 7 of 8 lights broke upon delivery. This is just completely unacceptable.. did I mention I already rewired my fixture so I can't just pop the fluorescent tubes back in.. Fortunately I am able to return the broken items for free but with an 87.5% failure rate on the the first attempt, there is no way I could allow myself to have replacements sent. I can't believe the end result would be any different! Hopefully this is an isolated incident. Order at your own risk and good luck!! I ordered some of the Hyperikon bulbs with far more reviews. Hopefully I will have better luck with them!! Pictures if the damage and 'protective' foam are attached.

I purchased these on behalf of a relative. I did my first every ballast bypass after watching multiple videos. I knew very little about lighting, though I was confident in wiring outlets and pulling wire.Here is the pertinent info. This is specifically for ASIN: B074M8KCJ1. I know how amazon likes to lump reviews.These are LED bulbs that replace a T8 or T12 florescent tube, and remove the ballast all together. The difference between the T8 and T12 is a 1/2" difference in tube diameter and a magnetic ballast vs an electric one. This doesn't matter to install these bulbs. They fit a 4' fixture.Something to note, as I found out, is that while most LED replacements are single ended for power, these are dual ended, which is more rare. What this means is that on most, you run the power and the neutral to a single end. The power would go to one prong and the neutral to the other. In contrast, these are dual ended and you run power to one end of the bulb and neutral to the opposite end.As far as installing them, I spent 20min and made two mistakes on the first one. Once I was familiar, it took maybe 10min to install the second set. On the first install, two tombstones were broken, so I replaced all four. The tombstone or keyway are the little pieces that the prongs go into when installing the bulb. If you hold them rightside up, they look like tombstones. I found them cheaply at my local big box in sets of two. I spent maybe $10 for 8 total.If you can use the existing tombstones or are replacing them, you can use the wire attached to the ballast. I believe it's 18ga. For safety sake, shut off the breaker to the fixture you're working on. I'm absolutely not saying that shutting off the light switch also breaks the power and that you shouldn't be touching live wires. For safety, just shut the breaker and the light switch off.Once that was done, I cut the wires as close to the ballast as possible, and removed it from the fixture. You can leave it, but it's just scrap after this. This gives you as much wire as possible to work with.Here is where a little guess work came in on my part. The diagram provided on the amazon page only showed one wire leading to one end. So that's how I wired it. I couldn't get answers anywhere else. I removed all the tombstones from both fixtures, because this was being installed in a barn and I wanted to make sure they were in good condition. The ones in the first fixture were all damaged, so I replaced them. the ones in the second fixture looked good, so I simply blew all the dust off and reused them.I only used one wire on the first fixture, so even though I had two wires to each tombstone on the second one, I cut one as flush as possible and left it alone. If you're using a new tombstone, strip ~1/2" off the end going in the tombstone and just push it in. Be warned that once you push it in, it's in for good. Think chinese finger trap. On the other end, strip ~1 of wire.Another thing I didn't know when putting only one wire to each end was whether it mattered if I powered the pins on the same side. These bulbs were labeled as working with shunted and non-shunted tombstones. I had to look that up. Basically, with a shunted tombstone, the power goes to both sides. It'll power both pins with one power wire. With a non-shunted, it only powers the side you add a wire to. So if you want both sides powered, you need to run a wire to both sides. In the interested of "it'll work either way" I added/kept the wires that would be to the outside of the fixture on both sides. I didn't know what would happen if I powered the outside pin on a bulb, on one side, then ran neutral to the inside pin on the other side of the same bulb. Running them in a line worked, so that's my suggestion unless someone says different.One you have the wires pushed into the tombstones, reassemble the fixture, minus the cover for the ballast and wires. Tuck them up so they don't get pinched when you put the cover back on. Before you tuck and cover, you need to attach it to the power. This is pretty much going to be a standard 12/2 wire. That's a 12ga wire with two lines in addition to the ground. If you run into a 12/3, which I did recently, just pay attention to which wires were used to power the ballast before. Any wires you aren't using should be trimmed flush to the tombstone or put a wire nut and maybe some electrical tape on them for saftey.Wire the neutral first by picking the two wired ends (one from each bulb), and placing them inline with the white neutral power wire, with the ends even. Grip by the insulated covers. Push on a wire nut and keep twisting till it stops. Give it a tug to make sure it's solid. Now repeat on the hot wire. Grab the wires from the opposite end of the bulbs and wire them to the hot.Once this is done, you're theoretically up and running. I recommend that before you seal it all up, you test it. Install one or all of the bulbs and then turn your breaker on. Then your switch. it should light up. If it does, then remove the bulbs, tuck the wires, reinstall the cover, and reinstall the bulbs. You should be good to go.As far as the bulbs themselves. I got the brightest ones for the stalls and grain room. They are brighter than the previous florescent bulbs. They don't have a diffuser, meaning a frosted covering to make the light go in all directions, but they cover what I believe is a 12'x12' stall easily, from a height of ~9-10'.The fit is tight. I had to push on the tombstone slightly to get them to fit in. The position of the tombstone is slightly adjustable so maybe I just had them in too far. The bulbs themselves are pretty flimsy. They have hard plastic on the ends with the pins. There is an LED light strip down the center. The "cover" that makes it round is just stiff, clear plastic. I felt I could pretty easily crush it and didn't even feel I could push on it to help guide the pins into the tombstones the way I would with even the glass bulbs. Instead, I pushed on the hard plastic ends. Having said that, I don't plan on handling them regularly. Once they're installed, I don't see any issue with this flimsiness. In fact, if they ever get scuffed, damaged, or dirty to the point of affecting light quality, I don't see why you couldn't just remove the plastic and let them be exposed. They're already not rated to be in super wet environments, so I don't see where it would matter.Anyway, I've been using them maybe 30min a day as I feed. They come on instantaneously and are very bright. I saw a review where someone said they were failing after a couple of years or something. I guess we'll see if that's all of them or a batch. Even if they do fail after 2 years, that's still less time than the ballasts lasted and replacing the bulbs is much easier and cheaper than replacing the ballasts when they go out.Ideally, you'd just start with LED fixtures, but this is a good product for those making a transition.

I just finished installing these LED bulbs in two different fixtures, the installation was super simple and only took me maybe 10 minutes a fixture to switch over (including Ballast removal).I'm quite familiar with replacing and converting my home incandescent and fluorescent bulbs to LED bulbs and as no surprise these bulbs provide much better illumination than what I originally had installed.The bulbs came VERY well packaged with not even a hint of shipment damage, and all of them worked properly at the first switch-on.I cannot comment on the longevity of the bulbs as I have just installed them, but I'll see how it goes.One thing of oddity, three of the four bulbs are instant on when flipping the power switch - but one has about a half to one second delay before turning on or off .My suspicion is that a dimmable bulb somehow got mixed in and made it into the shipping box.The filtering required to make the bulb dimmable causes a slight delay on turn-on and turn-off. It's not a big deal (unless you have OCD <grin>) because once it's on it works just like the other bulbs.So far I'm happy - I'll see what the future brings.

I've installed 12 of these so far in my garage and am very happy. The picture shows the new bulbs on the left and the original 5000k T8's (about 6 years old) on the right. You can see that the LED replacements are brighter and a much whiter light (there is a little more "glare" to them, harder to look at directly, so definitely the "Frosted" version helps but it IS a different type of point source lighting so it is to be expected and my fixtures are industrial and open). My old Phillips bulbs were a little faded, and certainly seem warmer colour temp, but for my purposes (work shop) I am sure the added brightness will be a good thing and I won't notice the cooler colour temp change eventually.They throw an even light, and very good light spread (mine are mounted at 11ft high). Very efficient at a lower wattage, AND one of the key reasons I chose them, they generate at least 10 degrees F less heat (tested using an infrared temp gun) than the original electronic ballast type. Instant on, no delay.Installation was straightforward for me (as I have electrical experience), but instructions are included. Basically these are double ended meaning that when you remove the ballast, you have to re-configure the remaining wires so that the Common AC Conductor (normally white) goes to both bulb sockets on one end, and the Hot (or "live") AC Conductor (normally black) goes to both bulb sockets on the other end. IN my case this was as easy as snipping most of the wires from the ballasts (which I intended to take to the hazardous waste depot) and used marrettes (wire nuts) to re-configure the tombstone sockets. If in doubt about how to do this safely, hire a certified electrician.I am definitely happy at this point. So far no bad bulbs, I have 12 more to install, but I have had a prior conversation with the seller and they are very responsive.

They really brighten up my 1000 sq ft garage I converted from fluorescent and made a big difference! Plus the energy savings as well I installed 24 of them Very good value for the moneyUpdate: One bulb did not work but Jesled quickly responded to me and offered some suggestions to confirm it was the bulb and then they replaced it Very happy to deal with them and can honestly say they are a company that stands behind the product!!

Product was delivered on time. No breakage and as described.Easy to replace my old tubes.Nice and bright.Would recommend.

I've had 12 of these (frosted bulbs) for awhile in my garage, easy to wire, (remove ballast, hot to one end, neutral to other) they work when it's cold out (Canada) no issues as yet. Bought another set of 12 to finish the rest of my lights.

Swapped out my fluorescent lights for these, insane difference it was almost to bright.
