Had a few bizarre discussions on this subject recently and thought I'd ask the peoples of Mumsnet.
Are you a 'big light' person or a lamps person?
For context, one of the neighbours opposite has a big bay window so it's possible to easily see the TV on the wall and the big overhead light which is always on at night.
Me, I can't seem to relax if the 'big light' is on and prefer soft, subdued light (lamps etc). In our house 'the big light' only goes on if you've lost an earring! 
One of my friends swears it's a male/female thing and in her view, women like atmospheric lighting and men just see lighting as a functional way to see and do things. I don't think you can reduce it to such stereotypes. To me, it's basically just a personal preference.
So, big light or lamps? Which are you?
