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.
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.
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.
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.
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.

I love the bright light of these and the power savings. The light they give off is bright and not tinted any undesirable color. There is a second of delay when turning on.Published 3 months ago by Amazon Customer
Works great in existing with no problems - just had to rewire to remove the old heat producing ballasts. Does not have any starting delay as mentioned in other reviews. Read morePublished 3 months ago by Amazon Customer
Just what I wanted; the only reason it's not five stars is the very poor instructions. Or it could be that I'm a thick headed, retired, boilermaker. Read morePublished 6 months ago by John G. Jerdon
