We bought 4 of these to replace T8s in two closet fixtures. First the good. When finally installed and operating, the light quality was good (tended to warm compared to the T8, but I've always hated the green cast from those tubes), illumination was better, the lights come on instantly, and there is no underlying ballast hum.
Now the Bad. When they arrived, none of the tubes functioned. Since it was a pain to ship them back, I took one apart to see what was wrong and determine if I could fix it. The wires leading from the LED Driver Printed Circuit Board to the main LED PCB were cut at the point they wrapped around the end. The cause was apparently a failure to secure the Driver PCB relative to the LED PCB. During shipping or other handling, differential motion sheared the wires. I took the other three tubes apart, and all four had failed in identical fashion. After application of new wire, solder, and a bit of cursing (trying to get the silly thing back into the aluminum extrusion), they were good as new! Better in fact, since I modified and rotated the end caps slightly to fix the orientation problem that another reviewer reported.
Would I buy more? Unlikely. I have plenty of other projects to do without any new volunteers.

I had a florescent fixture with two tubes that didn't work. The bulbs were about 10 years old and the ballast, which failed, was older. Rather than replace the bulbs and ballast I decided to give these LED tubes a try. They work and provide a comparable amount of light. The light is cooler and not greenish like many florescent lights. I personally like the quality of the light. To me it feels more like day light. These tubes fit the standard fixture but you must remove the ballast and wire directly to your household wire. All the wires going to one side of the fixture (one end of the tubes), is wired to the black wire (hot) and the other wires to the other end of the tubes is connected to the white wire. I cut the wires coming out of the balast (yellow on the left end and blue and red on the right end). TURN OFF the current to the fixture at the circuit box. It isn't worth electrocuting yourself to save energy. The wiring is easy but the reason I gave this 4 stars instead of 5 is that this requires more than just removing old tubes and putting these in their place. For some people, the wiring part may be daunting.

Assuming these bulbs are dependable, they seem like a very decent option. The cost of electricity in my case is about half of the bulbs they replaced but that will take many years to recoup the original sixty dollar price of each bulb. I must admit that I did it because I prefer the quality of the light and didn't like the interference of the ballast/florescent bulbs on my radio and sound system.

Addendum: of four tubes, one was dead on arrival. Waiting for replacement.

This is a very cool looking T-8 replacement unit. Most T-8 LEDs have an array of surface mount LEDs. This one has 20 1-watt LEDs and a heavy-duty heat sink. It looks and feels like a very high quality unit.

It didn't come with "instructions", just a wiring diagram on the label on back. Neutral to the two pins on one side, line to the two on the other side. It took me maybe five minutes to disassemble the fixture, remove the ballast and splice wires appropriately. Reassemble, insert the bulb and turn on the lights.

The weird part is that it takes a bit of time to start. About three seconds to begin, and another 0.5 or so to fade all the way up. Which is faster than some of the fluorescents when they're cold, but slower than many of mine. But it looks soooo coool. And puts out a good amount of light.

Although these lights are more energy efficient and give off a nice glow, the ones I received require approx 10 seconds to turn on. Much longer than a standard fluorescent tube. Rather annoying to flip the switch and wait and wait for the lights to turn on before I can enter a dark room. After emailing the manufacturer
with this question their only response was that it could be the updated power supply they have changed to. The description, however, states "instant on".
In some situations the delay probably wouldn't be an issue. So I am giving only 4 stars.

I'm only a couple days using this tube but pleased so far by performance. I bought one to test and am satisfied enough to put 3 more in the cart. I was concerned about heat but not a problem. Output is good, warm white is my preferred color, (wife says cool white makes her look like a zombie), only reason not 5 stars is price but hey all led products pricey. I've wasted a lot of money on more frivolous things. Gave some money to a dem congress critter--please forgive me. Am waiting for the company called "Switch" to produce really high powered led tubes, they are using some mysterious fluid to act as a heat sink in their bulbs, therefore able to use super ultra bright leds.

Update---------I have discovered these tubes are apparently not UL listed. That's bad. If you have a fire resulting from the use of non-UL listed lighting, your insurance company may not honor the claim. They are always looking for a reason not to pay.
