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

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 10 fluorescent light fixtures in my basement so I had to buy 40 of these to cover all of the fixtures. My wife and I followed the instructions and were able to bypass the ballasts and swap out all of the bulbs in about an hour. Neither of us are electricians and it was pretty easy. The first one took the longest because we had to really understand what we were doing. After that the others moved much quicker as we got the hang of it (me bypassing the ballast and her putting the bulbs in). These were way brighter that I expected so we are actually only using 2 per fixture instead of the 4 bulbs that were in them before, but I love that. And not I just have a bunch of extras just in case.

I bought about 250 of these bulbs. Used about 200. Not a bad one in the bunch. It has been about 5 months and not one died yet. You do have to rewire the fixtures. It takes time and some work. (BTW if you use the LEDs that still use the ballast, there is almost no energy savings.) By bypassing (removing) the ballast you save over 80%+ of the power. I checked with an ammeter to be sure. Some light fixtures may have tombstones that need to be replaced. (They have internal shunts) I have had a few bulbs 6? that had a flicker. (like an AC flicker). It was not really noticeable unless you were looking right at them. Maybe slightly dimmer than fluorescent tubes, but could be the color difference. BTW I like the frosted a lot better than the clear. Clear seem to glare and feel not as bright. At the time, it was a good price and they are working well.

I like how easy they are to install and are very bright. The bad is one of them is broken and I am past the 30 day warranty . The bulbs are still a great deal.

I have a 1200 square foot garage/ workshop that has 28 fixtures with t12 4 foot flourecent bulbs. About half the fixtures weren't illuminating, and I couldn't narrow down if it was the bulbs or the ballasts. Was considering new LED fixtures, then I stumbled across these bulbs. I am not an electrician by any means, but this project to remove the ballasts and rewire the fixtures to single end power was easier than expected. Took longer to climb up and down the ladder with the bulbs than to rewire. And at about 3 bucks per bulb, way cheaper than new LED fixtures! Ordered two boxes of 30...one came damaged but no.broken bulbs. I converted a few fixtures a night and was able to get the shop done over a week. Could have done it in a day if I focused lol. Just make sure that your tombstones are shunted and you'll be able to convert to single end power no problem. I was able to use all existing wires from the existing tombstones. See pictures for how I wired for SEP.

They are junk . Some didn't even work

Previous owner of my home installed 10 florescent fixtures in the basement (he got them free when his employer upgraded their light fixtures). I had previously replaced the bulbs in two of the fixtures with this same type of LED, but a different manufacturer. Those bulbs were clear, so you can see the LEDs along the light while these Sunco bulbs are frosted. I will probably replace the ones installed previously since I purchased a bundle of 30 (it was the cheapest way to get at least the 14 I needed under the Prime Day Special). You do need a small amount of DIY to rewire the fixtures, but it is not difficult. The results were fantastic, the basement is brighter and I am using 1/3 of the electricity. Now I just need to haul the old bulbs and ballasts to the Hazardous Waste Disposal Site in our town.

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.
