You need higher than normal levels of illumination in the bathroom to make the daily job of making yourself pretty easy there is nothing worse than no being able to see yourself properly in the mirror in the morning. The other end of this is the end of the day when you just want to relax in a warm bath, ambient soft light is what you want not light that would be bright enough for a tennis court!
