LEDwholesalers 11W LED T8 T10 24-inch Fluorescent Light Tube Replacement, White 1946WH

I bought the Two pack 11 watt 2 foot T8 LED tube lights from LEDwholesalers/Amazon:com, and it took me over twenty four hours to install them because it didn't have any installation drawings.When I ordered these two footer LED replacement tubes, at the same time I also ordered a set of the four tube four footers through LEDwolesalers/Amazon. These four footers did have installation stickers on each tube in addition to having it on a separate sheet of paper, and because they looked similar, I thought that I would maybe be able to use those drawings to get my two footers going. But just in case, just to make sure they were the same, I got out my Fluke77 meter and ohmed it out. Boy was I glad I did that, because I found out that the four footers are internally wired up differently than that of the two footers.I then got a hold of LEDwolesalers through my Amazon account, and within twenty four hours they did confirm that the my other four footers were wired up differently than the two footers, and they also included an installation drawing for the two footer. Thank you LEDwolesalers for your very quick response!After getting the installation drawings, it only took me about twenty minutes to install them, and turn them on. The lights has a one second delay before they light up, and when it did turn on, they were really bright!Compared to my new LEDwolesalers four footers, the color output of these LEDwolesalers two footers viewing them simultaneously is a little bit on the blue side. But if you compare the LEDwolesalers two footers to a four footer fluorescent tube simultaneously, the two footer is white, and the fluorescent tube has a slightly greenish color. The LEDwolesalers two footers are a lot brighter than my old four footer fluorescent tubes viewing them simultaneously.But there is a warning! The warning is that there are no standards for all of the manufactures to internally wire these replacements LED T8 tubes the same way, and if you are installing them for the first time, or replacing defective units, you better make sure that they are internally wired up the same. The first time you turn them on they could possibly catch on fire before your home circuit breaker pops off if they are not wired up right.!In other word's, when you buy a new replacement LED tube from any manufacture or company, don't install them if it doesn't have an installation drawing, or without looking at the installation drawing!!! PERIOD!!!. They are not plug and play like the replacement fluorescent tubes are!I am only giving three stars for this two footer LED replacement tube because of the missing installation instructions, other wise I would have given it a five star rating like I did the four footers. I sincerely hope that LEDwholesalers will check to make sure that all of their two footer LED tubes has installation drawing in their boxes when they ship them in the future, or at least paste a label with the drawing on the tubes like they have on their four footers that I got from them.

Great way to light an area at minimal cost, assuming this lasts a few years. Too soon to tell. We removed two 20W T12 tubes from a hall fixture and put in one of these 11W tube lights. It is brighter than the old pair, yet one can look directly at the light without seeing spots. This light comes on promptly with no noise. Our hall looks better.Our fixture is still ugly, yet we'll save enough to buy a single tube fixture. For now, It doesn't matter that our fixture is less reflective than a new fixture because all of the LED light shines out from the fixture rather than being reflected off of it. At $25 or less a bulb this is a great value investment. If we continue using it 8 hours/day we save >$10/year at 12¢/kWh. Since flipping the light on and off doesn't reduce this bulb's life as it did with the ballasted florescent, we will turn this off more even if we don't get a vacancy sensor installed.In our narrow halls a 9W light with 115° light distribution angle would be ideal, but this is much better than we had. The warm light (3100K is not as yellowish as incandescent) is sufficient that we ponder converting some vanity light sconces. One less mercury tube that could break in our home.FYI: Obviously changing a light is cheapest if you DIY. This is closer to the house wiring than some homeowners care to get, but is well within most people's ability if they have a secure ladder, have no kid or pet running around handling stuff, turn off the power first, and look carefully at the clearly labeled diagram and tube connections. Certainly easier than replacing a ballast in ones own home.If one were extremely cheap, the contacts are both on one side so corroded contacts on the other end of the fixture wouldn't need to be replaced. However, anyone installing this themselves must remove the old ballast and wire the hot and neutral to the correct sides of the contact. This may require proper wire to extend between the house wires and the contacts. Simply using blue wires from the removed ballast surely violates code, and making a bad connection between wires creates a spark hazard. If you have enough lights in a home or business, the savings may be worth hiring an electrician.

Light arrived in good time .The directions on the web site say wire at both ends ,"Power is to be applied to both ends of the tube -- 1 end to Live/Hot and the other end to Neutral." this is not the case , the bulb came with different directions and the tube the light came in had a different wiring diagram . I tried the power L/N at both ends first and that was wrong , then I tried power at 1 end with a L/N in the socket. That was the right way , I still do not know what to do with the starter that came with the light .The light worked ok when I figured it out,the light is bright . I hope it will last a while .

These put out a bright, very white light, from a standard fluorescent light form factor. They are an excellent replacement for fluorescent lights. I am glad to be rid of fluorescent lamp changes, hazardous disposal hassles, awkward starting routines and ballast replacements.These lamps require removing the ballast and rewiring AC power directly to the bulbs. This is no harder than replacing a ballast. Just be careful to know the proper wiring for the bulb. I appear to have received two different types of bulbs, one required the AC power to be connected to the two pins on one end, and the other required one power connection to each end.

These were pretty straight forward to install, and the typical do-it-yourself installer can easily do it if they know the difference bewteen the nuetral/common and the feed/hot wire.We marked the hot atombstone with black magic marker, and made stickers to indicate teh fixture has been converted, and that standard flourescent tubes can not be used.They are solidly built, and hopefully will last for years. We winterize many of our buildings and don't heat them. Flourescents tend to have short lives due to occaisionaly operating below zero.
