The first thing to consider is the look of the light itself. This may be a wall light, bathroom mirror light or ceiling light, and each of these types offers a whole variety of choice. If you have a bathroom with chrome based fittings, such as chrome taps, chrome towel rails and chrome handles on bathroom cupboards then it's probably a good idea to consider opting for bathroom lights with a chrome finish. Nickel plated lighting offers a beautifully warm look, but it's generally best to complement chrome with chrome rather than mix nickel and chrome together.
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.
Layering and combining ; If you have no idea how to start the installation process, you might want to consider layering lights. This is the process of combining lights based on their purpose. The first thing you should do is choose a good task light. Task lighting fixtures can be ceiling downlights or wall sconces. These are great for interior design work that serves a specific purpose. You can place them close to the vanity counter or the mirror. Task lighting will make it easier for you to do a variety of tasks in the bathroom.
Ambient lighting is another part of light layering. These are usually your typical uplights. They direct light upwards to allow the light to bounce off the ceiling and into the rest of the room. It softens the light and creates a good glow. Next is accent lighting. This is the kind of lighting that will give an additional spark to the lighting of the room. You can choose to dim it or increase the glare depending on your needs.
