Sunco 30 Pack T8 LED Bulbs 4 Foot, Tube Light Bulbs Ballast Bypass, 48 Inch Fluorescent Replacement, 2200 LM, 18W, 5000K Daylight, Single Ended Power, Type B, Frosted Lens UL

I have purchased 60 of these bulbs and love them. I have had broken ones on every shipment and every time I talk to Amazon and they gave me a credit for the broken bulbs. It sounds like most people get bulbs sent to them from the factory. These have made my garage and Airbnb so much brighter and more joyful to be inside. it takes me about 10 minutes for every four bulb fixture that I install them in. I have other bulbs that need LEDs but I’m waiting for the cost to come down because I don’t use them very often in storage rooms and attics. I feel as though the company could put more information on the standard T8 wattage and energy savings on the page to sell more of their product. From what I can tell it’s about half the power? Per bulb? It’s definitely more light and a more enjoyable light. One of the best features most people aren’t talking about Hiar is that the instant on! They turn on instantly where is so many fluorescent tubes have to click a few times and pop on and then warm up before they even bright. These babies are the stuff! I’m down to needing about 18 more of these, and I think I’m going to just wait until the next sale as there are other companies selling them cheaper now. But I’m sticking with this one. They work and work really well after a whole year. Not one bad bulb yet which means not one bad LED driver! This is huge, especially with some thing that can take such a variable amount of power. Hopefully the entire world grasp this technology and keeps replacing all the fluorescent gas tube bulbs. I wasn’t a big fan of the CFL lightbulbs that came out in between incandescence and LEDs. They were junk and such a waste of resources, time, money, and mercury into the environment. I’ve also spent a lot of money on other LED bulbs that claim to be 50,000 our bulbs and didn’t last more than a year or two. I know it’s not the diode itself, but generally the power conversion/drivers. Once the entire industry globally gets providing clean power to the LEDs, they will last a lot longer Got into a good routine with replacement: 1) turn off all power to lights; 2) remove covers; 3) cut positive and negative wires at ballast, cut old negative wires as short as possible to old tombstones; 4) remove ballast and tombstone plates on one end; 5) replace with non-shunted tombstones on plates; 6) wire all similar wires together from tombstones; 7) replace plates with new tombstones and connect similar color wires; 8) replace covers; 9) install lights with correct ends into non shunted tombstones.

Great product, easy to install, perfect brightness and color. Everything it said it would be. Great packing. Will use this company again

I have a newer house but the electrician had fluorescent lights left over from another job and it saved us some money. 5 years later I wanted to upgrade them as they were using a lot more energy than I had thought. The old system had shunted tombstones and ballasts. The good news is the new lights need way less wiring than the old ones did. Once I did the first one it was time consuming but quite simple. I was actually able to remove the shunt from the old tombstone on the powered end and just cut the wires on the other end and leave than tombstone shunted. I have 24 tubes, so it still uses quite a bit of power (albeit about half of what it replaced), but it's brighter and won't smash and poison me if it gets hit. Overall it was worth doing, and was easier than I expected.

Used these LED replacement bulbs to upgrade the lighting in my shop/garage. Conversion was simple, found plenty of examples on YouTube on how to do this - but I also have an electrician friend who confirmed my approach before I attempted this. I'm pretty cautious around any electrical work. First you have to make sure your fixture(s) use un-shunted tombstones (the ends the bulbs slide into) by doing a simple continuity test. Then just remove the ballast(s) , pull out the tombstones and rewire for single end power LED bulbs (again - YouTube has plenty of examples on ways to do this). Now I have great light in my garage. I attached two pictures, one showing my fixture with the new LED bulbs and wiring before putting the ballast cover back on to hide the wires, and the other picture shows the light turned on with it's diffuse cover in place. I have several other fluorescent fixtures around my house that I plan to convert to LED in the near future using these bulbs. If you are pretty handy, this should be no problem for you to tackle. Otherwise, I'd suggest getting a licensed electrician to do it for you. Either way, these bulbs work great. If the bulbs you are converting are exposed (No cover), I'd recommend getting frosted bulbs instead of clear since you can see each little LED light inside the tube. My only complaint is the bulbs were not very well protected in the packaging they were shipped in and one of the bulbs got crushed in shipping. If you do purchase these bulbs, be sure to check all your bulbs immediately so you can return them if necessary.

Excellent product. Too bad the Line & Neutral aren’t marked, but that’s easy to determine .

Work great! None broken. Nice, bright color.... no flickering.

Within 5-15 mins they just stopped working! Never seen something like this

Great replacement for the older style easy to install

Converted all 30 tubes in the basement. With power on (maybe a little careless) I removed one marret, pulled off ballast wires replacing the marret on the power wire, then did the same on the second power wire. Now with the ballast unpowered I removed it. Then I removed the wires in all the tombstones reusing the old tombstones. I cut up the ballast wires making jumpers of one color of wire for the left side of the tombstones and another color for the right side making one long lead for each color. I then put one long lead into each of the marrets on the power wires. On the other end of tombstones I simply removed the wires totally and put them back in the fixture. 2 hrs. later all 30 lights worked perfectly with a substantially brighter family room and bedrooms. Did 1, 2 and 4 tube fixtures the same and all worked well.

Retrofit basement fluorescent lights. A sticker should be included warning the the light fixture has been retrofitted to LED. and not to install a fluorescent tube.

I wired direct. They are in a shop and are way better than the fluorescent ones that they replaced

Very well made light tubes, extra good individual rapping on tube containers.

These lamps are bright but as I got to the last five I discovered that one of them was shattered, It looks like the straps used to secure the boxes to a pallet was to tight. Now I can't return the order because I installed most of them, threw out the individual tube boxes and also Amazon is out of stock. After retrofitting all the lamp holders I can't be without light in my shop, the Shipping needs to be better.
