This space is one can be a room for relaxation, though it is also a functional space, and the moment we think about what lighting to use we have to think about all these things. Efficient lighting will allow us to carry out all the activities relating to these rooms without creating any discomfort.
There is no rule such that the bathroom lighting should be provided only in the ceiling or is better if it is provided at the sides or on top of the mirror. One has to fix the bathroom lightings according to one's taste and the mood that he or she wants to bring into the room. Even for a small bathroom, people, these days, go for two or more lighting fixtures. Thus, lighting is the most important factor to be considered in any modern bathrooms.
It is wise to use flush-mounted ceiling fixtures, owing to the fact that these come with bulbs that are enclosed by a kind of cover. The cover is essential as it acts somewhat like a lamp shade and helps in diffusing the light as well as protecting hot bulbs from breaking and cracking from contact with water vapor. The best would be to have the right balance of ambient bathroom lighting and task bathroom lighting. This will give your bathroom proper illumination and make your bathroom experience worthwhile.
Another important aspect in choosing lighting fixtures represent problems that may arise through contact between a heated bulb and water vapour from the bath. Such inconvenience can be avoided if spot type lighting bodies are used.
