I probably don’t get out as much as some here, but while I’ve noticed a lot of variety in campsite lighting, I’ve never seen anything that actually affected me significantly. Maybe I’ve just been lucky, or tolerant, and I generally don’t stay many places that pack people in like sardines. Some folks have very spartan campsites, while others seem to fill the entire space with displays, decorations, outside furniture, canopies, equipment & appliances. Lighting seems like just another aspect of that phenomenon.
