Went to Lowes and bought an 8' track lighting system to mount over my "high
end" guitar wall.

Installed the track, wired it up and put the first of four fixtures in it.
Worked fine.
Installed the second fixture. Worked fine.

Installed the third. Didn't work. Changed the bulb. Still didn't work.
Fiddled with it for a while then decided it is probably bad and put it
aside.

Installed the forth fixture. Didn't work. Changed the bulb, still didn't
work.
Fiddled around, still didn't work.

Finally took it apart to figure out why.

It could never have worked. It was put together wrong and if I had happened
to get the contacts to connect, it would have shorted out the supply
voltage.

I took the other one that didn't work apart. Same thing.

Looked at the boxes they came in. Sure enough. Brand name is "Portfolio"
but "Made in China" is printed in small print on the box.

Moral: Don't buy any electrical appliances or potentially dangerous/fire
producing items that are made in China. I am not kidding. This is not
the first time I've run into this. Some of the products being made in
China are dangerous. There is obviously no production or quality control in
some of their manufacturing facilities.

They should stick to noodles.
