Great to hear we all think alike on the windows. I wanted glass block up high to let light in and not fret about security. But since mine was built in the midst of Covid, the builder couldn't get any glass block (so he says!) so I have no windows. I'm looking at additional lighting for the interior but with the high ceilings, the 8 large LED fixtures so far shed quite a bit of light. Will likely get some of those LED lights on a stand to use under/around a car if/when I put in a hoist.
