E s is again this time of the year, in which Ute Günther walks with horror through the streets: She looks in kitchens with neon tube light, sees people working in a funzely line of a desk lamp or playing children under ceiling light fluters with Lego. Outside it's dark, and inside it's not really bright either. At least not in such a way that a sense of well-being would be set. "I am always surprised at how people can live," says Ute Günther, a self-employed interior designer from Bavaria. "Most people are not aware of the catastrophic lighting conditions they are actually living in." This is not difficult to change.
