Wow, I'm amazed of how easy it was to replace my old florescent tube lights with LED Tubes.
I'm tired of buying florescent light tubes by the case just to keep up with burned out tubes. And replacing the ballasts. With the rising cost of electricity I started replacing lights with LED lights. A $100 gift card started me on a very pleasant journey. That gift card bought me two four foot LED T8 18-Watt Tube lights (free shipping). The installation was simple. Throw away those old tubes, remove that expensive ballast, wire one end hot, and that is it. A utility room as bright as day, tubes that last 10 - 20 years, and using 85% less electricity.

Very good light after install.
The lights were not to hard to install, but they were a unique learning experience. LED' s don't just go in like replacement flourexent bulges, the first time, unless you are good with electrical, I would buy the complete LED fixture.

Best value LED tube bulb
On a previous purchase on the same item, I compared all of the LED 4ft tube light bulbs to replace my florescent bulbs. I discovered that florescent bulbs contain mercury gas, which is toxic. These where the cheapest and the brightness level was one of the brightest on Homedepot's site. They are indeed a very bright white light, brighter than the florescent bulbs that I was using. The instructions are pretty easy to follow. The only tool I needed is a set of wire cutters. The only draw-back is the instructions are for a single bulb installation. I have a double bulb unit. Making sure that the power is switched off going to the light unit, just join the wires coming from the right side of each bulb receptacle together and join the wires from the left side together. And tie in with the appropriate electrical house feed. You will be eliminating the use of the ballast. You no longer have to wait for the bulbs to warm up to be completely on. It's pretty much instant on now. Homedepot needs to carry these in their retail stores, not just their website. The bulbs where safely packed for shipping. Buy this, you'll be glad you did.

good but not great
i bought 4 lamps to retrofit 2 existing indirect cove lights. only 3 out of the 4 lamps i purchased worked. I had to return 1 right away. These are sold via internet only so I couldn't get a replacement right away. A few days later one of the lamps started making an intermittent buzzing or crackling sound. Now I am down to a 50% success rate. The lamps are easy to install, just remove the ballast and wire one socket end with the line and neutral wires from the ballast connection. unfortunately only one end of these lamps can accept power so you have to make sure you install them with the correct end matching the end you wired for power. the other disadvantage is that with only one end to accept power most of the common socket ends have to be cut and spliced so that the power and neutral can be attached to the same end. Its a much easier installation if one end can be power and the other end can be neutral. I have also purchased several LED retrofit lamps from a competitor, and they accept any combination of 120v and neutral on any of the 4 pins, making the install easier. after the installation i got out my light level meter and noted the difference in brightness between this and a competitors LED retrofit lamp. the color was great, but the light level was about 12% less than a slightly more expensive alternative. This is a cheaper option but it has less LED's and less features. I also experienced a 50% failure rate in the first week of operation that may or may not be typical for this product.
