Where do you find good artificial lightning? A good light needs good color accuracy, enough brightness, needs to change the colour temperature and brightness throughout the day. Then you still need ultraviolet radiation to get vitamin D3. I sit here under a skylight that is pointed to the south. If that's too hot/cold I lower the roller shutter. I very rarely need artificial light here. When I'm at my girlfriend's place there is barely any natural light, just artificial light and the lack of light leads to a drop in the mood.
