Why 'Acorn Lights' Are Bad
I'm glad those aren't my bedroom windows. Notice how this fixture type doesn't cast much light on the ground? Sure glares in the windows (and eyes) nicely, though.
These are dorms at the University of Utah. The campus has hundreds of these absurd lights burning all night long. It's a state funded school and this is how they're using tax money. I'm sure tuition also helps foot the electricity bill.
