Sunco 50 Pack T8 LED Bulbs 4 Foot, Tube Light Bulbs Ballast Bypass, 48 Inch Fluorescent Replacement, 2200 LM, 18W, 6000K Daylight Deluxe, Single Ended Power, Type B, Frosted Lens UL

The only issue I had with these lamps is that UPS delivered them and the driver said "sorry buddy but sounds like some are broken and I can't take them back sorry by". So I immediately took the unopened box of broken tubes to a nearby UPS store and returned to Amazon. Amazon quickly sent a new case of 50 delivered by Amazon with no issues. As I said in a previous review of a box of 30 they are very nice lamps, every one worked, great color and brightness. I have been rebuilding/relamping all the florescent lighting in my church to these led lamps. Will need to order another box soon.

Ordered a 50-bulb pack of 4' T8 LED bulbs from SUNCO. Order was received quickly. Bulbs were VERY well-packed, undamaged. Have installed about twenty bulbs so far, all worked perfectly and very brightly. Removing the ballasts and rewiring the fixture for direct contact to the bulbs was a very simple job, reusing the wire in the fixtures. The fixtures were originally a mix of T8 and T12 bulbs and old magnetic ballasts and newer electronic ballasts, and the T8 LED bulbs fit and operated perfectly in all after the minor rewiring task. The LED bulbs are instant on, even in very cold temperatures in an unheated shop building, and give full brightness even at the low temperatures.The SUNCO LED bulbs were an economically priced, high-quality solution to replacing and upgrading the old fluorescent fixtures in my shop building.

I'm an electrician & have been using these bulbs for 2 yrs now. I haven't had a callback for a burnt-out bulb once. This means a lot to me as I have to guarantee/warranty my services & materials to my customers. They install perfectly, don't get warm, they're very bright & the color is great. They arrive in nice foam packaging to prevent breakage. I have purchased hundreds of these & will continue to do so

I've been buying these for a few year, a box of 50 at a time. These are an easy and inexpensive upgrade to the old 4 tube 4' long fluorescents we have everywhere in our church. I have had a few broken upon delivery, quick replacement at no cost, I have not had any burn out and some are going on 3 years old. The one thing I love is the fact that 2 bulbs replace the old 4 fluorescent ones and have more light and it is a white light so much easier to see things, gets rid of the old dingy yellow look that was everywhere. Great purchase, I think the 4th pack will finish up my project, about 96 light fixtures in total to upgrade.

These lights are ideal replacements for old style fluorescent bulbs. Installation is simple, just cut the wires off one end of the tombstones and wire one hot and one common from each of the tombstones on the other end. I had bought replacement tombstones for this but returned them as not needed.One BIG complaint was out of 12 bulbs in the package, one was broken. I had already installed 8 of them and couldn't find a way to return just one bulb, so I ate it. The box had no apparent sign of damage either, so I suspect it was a return or something.

There nice.

Great bulbs, and very easy to install. I bypassed the ballast, and these bulbs worked very well. Much brighter than the old fluorescent bulbs that were being used previously. Out of 50 bulbs in the package, only one was broken (somehow in the middle of the box; box was undamaged). I would definitely buy these again if I need more bulbs in the future.

After putting them in, we noticed the lights were way too dim. We left it alone and thought this was normal because they were LED lights. We decided to open them back up 2 weeks later and found this- some were broken, yellow and even corroded. We are returning them today. Don’t purchase.
