4 Pack of neiLite® 4 Foot, 22 watt Bright, LED Replacement Bulb for Fluorescent Fixtures, UL and ETL Listed, 85-277 VAC, Frosted Diffuser

Goodbye annoying, troublesome flourescents!I resisted buying these at first because I was a little nervous about having to alter the wiring in my light fixtures.Don't be. Just study the printed instructions for a few minutes and you'll get it. I can't read a schematic for beans, but found all this to be quite easy to understand. (Main thing to know: the black line in the illustration is your black 120v wire, and the light grey line is your white 120v wire.) Just follow the diagram.I've installed six of these in three fixtures and am so glad I did. A little work on the ladder now means I won't be up on that ladder replacing bulbs again for many years to come.These bulbs turn on instantly, first time, every time and they have a very pleasing color temperature: a warmer color closer to a traditional tungsten light bulb, not the harsh, brilliant "sunlight" white of similar products. (The color temperature is indicated as a "K" value. These are 4000-4500K. Anything higher than that is getting too brilliant white for my taste.) They produce tons of light without making me feel like I'm in an operating room. The light just doesn't have that artificial glare to it.I am now keeping at least four of these on the shelf to convert one fixture at a time as either the old flourescent bulbs go or the ballast does.WHY RE-WIRING IS BETTER (BECAUSE YOU GET RID OF THE BALLAST)The ballast is a transformer about the size of a hot dog bun that changes the voltage to support flourescent bulbs. But, like flourescent bulbs, the ballast doesn't last forever. If the ballast goes, you can put in as many new bulbs as you want and your light still won't work.I finally converted my fixtures because I noticed the bulbs weren't lasting more than six months, some as little as one month. Bad ballast. So, up and down the ladder and many trips to Home Depot to buy those annoying flourescent bulbs (which you really should recycle due to the mercury in them). After I got tired of that, I couldn't wait to say bye-bye to the whole technology. Which is why these LED bulbs were invented. I will keep converting, one by one, any time a bulb or ballast goes. (It's actually kind of fun.)But you'll find an LED product similar to this that does NOT require you to remove the ballast. Easier, yes. Better? Definitely not. When that ballast goes, you're back to the same problem. Even when you have a working ballast, it's wasting electricity by having to convert to a different voltage. Plus, they hum. So that's three good reasons to ditch the ballast and go with this kind of LED bulb. Reason #4: The LEDs that work with a ballast are also considerably more expensive. Glad I was not tempted by the little bit of convenience they offer.The nieLite LED bulbs are packaged in several layers of protection for shipping, and all the ones I've installed work great. And they come with warning labels to put on your fixture alerting people not to use flourescents any more in that fixture. (However, I thought the labels were too small, so I printed up big, red warnings that I taped inside the reflector of each fixture. There is now no chance of a future mistake.)Basically, when you make the switch you are getting a near-permanent bulb that is much more energy efficient, reliable, quiet, and pleasant than your old flourescents you've spent all that money on over the years.Go ahead -- make the switch. If you're still afraid, it's still worth it to call in an electrician to do it. Once you get the hang of it, each one takes about ten minutes, so the bill won't be too high.

There is some modification required to the existing light fixture, but this is very easy to do. There may be other options available at box stores that do not require this modification. These lights are bright. The price on Amazon is slightly higher than box store prices, but not by much. May pay for you to shop around, but there is nothing wrong with these lights.

I bought 2 of these. At first I thought the price was a bit steep but the reviews all said they were better packed than many competing units and they also had more lumens of output. I was not disappointed. I have never seen lamps so well packed. You could have driven a truck over them and not hurt them. Each lamp packed inside a 4 ft PVC pipe with sealed on ends. Good instructions for modding the lamp housing to remove ballast from circuit and provide 120-240vac across the tubes. These are automatic multivoltage so work equally well on 120vac (USA) and 240vac (Europe/Asia) circuits. They are also awesomely bright. They appear at least twice as bright as the 32 Watt T12 fluorescent lamps they replaced. They start virtually instantly as well. These are well worth the money.

Put these in an existing direct wired ballast free fluorescent LED fixture which is rated at the same specs. All four of them blew immediately. Ended up buying a higher quality from Home Depot that worked perfectly.

Easy to install. Instant on. Bright. Good color spectrum for the kitchen.I notice a slight 60 Hz flicker with these out of the corner of my eye, but it's not nearly as noticeable as with a traditional fluorescent tube.

it worked well but I like 5000K instead

After a friend of mine purchased them from one of the local home supply houses, I decided to get some for my kitchen. I have 2 doubles in my kitchen, so I ordered 4 tubes.Although the shipping box was surprisingly heavy, the actual tubes are very light and easy to handle. Since the protective cardboard tubing is quite sturdy, my grandson recommends saving them for Star Wars Light Sabers. (Some well placed paint, insert an LED flashlight with an extension wire to an outside micro switch and cover the end with a bit of well placed bubble wrap. Makes a great recycling toy!) Instructions were very clear and easy to follow. The color is slightly softer than daylight but very acceptable for my wife who has a vision problem.I had a few questions and received very prompt responses. Although I could have purchased them locally, I prefer dealing through Amazon.I found that cutting the wires on the ends made it difficult for me to connect the wires with the supplied wire nuts. In the future I plan to use crimp connectors since I have a crimping tool and I plan to get more tubes for the bathrooms and my office/storage room.
