Here is a home made recessed light that I pulled out from a job 2 years ago. This was installed over a shower. He could have just bought a $10 recessed light.
But No!! this "McGyver like" Side jobber had bigger plans. He made use of the items he had in back of his Red El Camino with white sport stripe
He decided that he was going to cut a 2' x 2' hole in the ceiling, then go into attic and suspend this masterpiece from a rafter above the hole.
Of course he then finished the job off using a leftover 2'x2' plastic lens from a fluorescent lay in (troffer) fixture, held in place with ... (you guessed it) Romex staples !! which he painstakingly painted white like the true artisan he was.
