In a renovation on the other hand we have to consider what effect a new skylight will have on the efficiency of the existing building. In some cases the additional sunlight (and therefore heat) can help reduce the amount of energy needed to heat the house. It depends greatly on the local climate but also on the design of the building envelope of the house.
Candles also offer wonderful sparkle and set a distinctly relaxing romantic tone. Just make sure you keep them well away from any flammable objects such as towels and hair and never leave them unattended.
A floor lamp nestled against a window is a smart substitute for daylight so that when the sun goes down an ambient glow will pour in from a similar direction to balance the central light overhead.
