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 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 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 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.

excellent

When you flip the switch on the wall, the lights come on. That's what you want out of a light bulb. After bypassing the ballast, a different brand of T8 LEDs would not always turn on. The Sunco lights always turn on immediately.
