I would recommend avoiding glass carboys for fermenting. They are heavy, especially when filled, difficult to clean with their narrow mouths, and quite dangerous if they shatter when you accidentally drop them. (They're easy to drop while you're cleaning them and they're wet and slippery.) There are numerous accounts on home brewing forums of trips to the emergency room because a glass carboy broke and injured someone.
PET plastic fermenters (Better Bottle, FermZilla, Fermonster, etc.) are much nicer to work with.
My experience has been exactly the opposite. My neighborhood went from yellow, sodium lighting to stark white LEDs a few years ago. The result, to my eyes, is that the contrast between what is lit by the street lights and surrounding dark areas is much higher. Perhaps what is needed is better diffusion onto the ground.
This reminded me of xjump, a very addictive falling tower game where you must continue to jump to the next highest platform as the lower platforms collapse beneath you.
This playlist with a new player being led by an experienced player was very helpful for me when I was learning to play. Still haven't ascended, but what an addictive game.
