Sixteenth of an inch sounds like a reason to sleep fine, honestly.

Man, that old timer knew what he was talking about. I had a similar wake up call when a framer showed me how to pull a line with just two nails and some mason's twine, and it beat my fancy setup every time. Now I keep a chalk box in my pouch at all times, batteries and lasers can fail but a snapped line never lies.

Ngl, I felt this in my bones. I was doing the same thing with my desk lamp for model painting, and I thought I was just getting old or something. Turns out cranking 6500K right into your face is a fast track to eye strain and headaches, especially after an hour. Dropping mine to like 70% and adding a little warm bias made a world of difference for seeing the actual edges and not just the glare. You're not late at all, I think most of us just deal with the harsh light because that's what the hardware store sells. Honestly, it's a total game changer once you stop treating your shop like a warehouse.
