I like lights; especially unique designs. But I also like to save on the electricity bill. So we have solar heating of the geyser and enough glass to provide us with daylight during most of the day. The guest room has its own shower and if guests use it during the daylight there is no need to switch the light on. In case of need we do have a blue reading light with energy-saving LEDs. This light also creates an blue-ish sphere, even by daylight.
