NOT TRUE!!!  First of all, if your house burns down, and if the insurance
company finds that YOU built and installed the fixture, yea, they'll
probably pay you.  But best of luck finding insurance on your future home.

Secondly, fixtures that are built from UL components does NOT make them UL
LIsted....  HUGE difference.  Fixtures that are UL approved are TESTED... to
make sure they meet code, and more importantly, to make sure they do not
exceed the temperature parameters for the fixture type.

Anybody can put a socket in a V8 Juice can and call it recessed lighting,
but voila the DIFFERENCE between 'that' and the 'real thing'...

Where did you have in mind?
Home made fixtures not only are legal,
but most hardware stores sell kits for amateurs.
It's a hobby some places.
