Part of the reason for automating it was that I wanted to integrate the lamp into my home theater setup: When the movie starts, the lamp slowly closes and synchronously dims out (guests always react with a smile to this). Pressing the pause button dims it up again and gives one just enough light to find the bathroom ;-)

I have the one with copper inside coating, it works well as a lamp above the dining table with an 800 lumen LED lamp in it. I usually don't even have it set to the highest brightness.

Oh, no: the practical reason to keep it closed is when you switch it on at night, it shouldn’t suddenly brighten up the room at max volume, but open up progressively so your eyes can accomodate.

Of course if you live with someone, you don’t switch on the lights at night ;)
