MY dad was a lighting engineer/sales person, and I being an artistic-type person....got into looking at cool lighting of various types.
I always loved theater/dance and rock-concert lighting!
In in fact as they fork-lifted out the gigantic spools of the Lighting Curtain from MSG-- I took a pic of them!
But you certainly have passed me long ago!
Well done! {again}
And FYI......
LED lighting tends to be cooler (relatively speaking) than incandescent light bulbs.
