T8 LED Replacement, 25-Pack, 18W 4-Foot T8 LED Light Tube, 6000K, Daylight, Super Bright White, Double End Power, Frosted Cover

for the price, these things are just a great way to get rid of the old fluorescent tubes & ballasts, and the wiring is nice and easy with the double-ended power -- hot to one end of the bulb, and neutral to the other end. I was able to do 11 4-bulb fixtures in about 6 hours. no tombstone replacement required, which really sped up the process.basically, all the red & blue wires on one end of the light go to the black incoming power line (hot), and the yellow wires on the opposite end of the light go to the white (neutral). I used wall-nuts for this, which definitely helped speed up the process.these lights are definitely brighter, and they're also much whiter than the fluorescents. also, all of the 44 bulbs I installed were undamaged, and worked perfectly. there is roughly a 1-second startup for these, but that doesn't bother me at all.there's lots of LED tubes on amazon, and I know that at least these are really good ones! oh, and we did the frosted covers for ours too -- very nice, and just very happy overall.

I retrofitted our 4' shop lights (16 tubes) and 4 kitchen lights a year ago in Sept 2017. After a year of constant use, we LOVE the instant on of the LEDs and the super bright light. Colors show perfectly as well, unlike some gas tubes we have used in the last 20 years. I totally recommend to anyone who has fluorescent tubes and wants better light, instant light, especially when cold, and great energy savings. The only modification is you simply remove the ballasts and just run power straight to both sides. Instructions included. Very easy.

Good

Great LED bulbs. I purchased the pack of ten. They are very easy to install after a simple retrofit of the lamp. Nice and bright. I did have a small technical problem with flickering in which the Seller communicated immediately with me. A+ for that. I had a automatic sensor in place of the light switch, once I changed back to a decor switch the trouble was gone.

Purchased box of 25. Rewired shop lights, easy 2 ended connection. Hint for anyone rewiring, buy some quick connectors. I have 4 and 6 plugin quick connectors makes it go extremely fast, 5 minutes per fixture. So I retro 4 fixtures so far. 20 tubes and all work great. I think they had a burn in time, because they seem to get brighter over time. Only issue which is not a problem is there is a delay of one second. But the lights are much brighter than my florescent 8ts. And definitely can see much better. Put these in my garage and basement.

I purchased these as a replacement for many dying lights. Half the ballasts had gone bad. When I read up on replacing fluorescent tubes with LED tubes, I thought this sounded interesting. Sure enough it worked great. For our fixtures all we had to do was cut the wires coming out ballasts. Tie all wires on one side of the fixture together with the hot line in. Wires on opposite side of fixture were all tied together with neutral line in. Done. Bulbs are bright, cool light. Put out much more light than we were getting with fluorescent tubes. A big energy savings too. I would highly recommend.

I have replaced 18 twin bulb fixtures and one 4 bulb fixtures to date with no issues. Bulbs come well packaged and work instantly. I have had no failures with any bulbs and are working splendidly. these lights give off a white light and are brighter than fluorescent tubes. My 2nd set of 25 had minor dents in the top row from shipping but worked fine. the dents were on the backside of the tube and with a little squeeze, the dents almost disappeared, not that it was a big deal since that part of the bulb is hidden once installed. The reviews of these bulbs were the reason I chose them and as per my experience, I know I will purchase them again.

Easy to rewire fixtures, about an hour to do five four tube fixtures. A whole lot brighter than what was there. Liked them so much I ordered another box for the rest of my lights. Now I'll have to see how they hold up. These lamps take a second or less to light up after the switch is turned on. It's no problem for me in my detached garage. Might be a problem for some installment applications.Just received and installed the rest of my lamps. They all worked, so no send back hassles. I put my Fluke meter on one 4 tube fixture, with the T8s it read about 1.7 amps load, with the LED lamps it read 0.65amps. Hopefully a picture of the tag on the tube shows anyone what they might want to know.Four years later and have not had any problems. All 48 of them still working.Five years still all working.
