I have one light, with a 40-watt lightbulb, that is on 24/7 and gives enough light for every room----even the bathroom, where I rarely turn-on the light (even when showering).
My blinds are ALWAYS closed (there's plenty of light, still).
I have lived here 17 years, and the overhead kitchen light, has never, ever, been changed (it's only been turned-on, a handful of times).
I wear sunglasses, even on overcast days.
