Bath lighting must meet three conditions: to be functional, aesthetic and to have a special ambiance. For the daily tasks (shaving, make up, etc.) you needed a strong light and for moments of relaxation, such as a bath in the tub, you need a discreet light. Also the bulbs that you use must provide the amount of light needed to properly light this room.
Task lighting: Task lighting should allow you to groom yourself efficiently, not create shadows and special effects, although no doubt it's fine if you can easlily incorporate those suitably in your lights arrangements. For task lighting around the mirror, place the light fittings on each side of it. The lighting should illuminate the person before the mirror rather than focus on the mirror. Generally speaking, the lights should illuminate your face fully and minimize shadows under your eyes and chin. It's also possible to wish to install lighting inside the bathroom cabinets so it is easier to consider things placed inside. Also install lighting fixtures over the bath area and toilet.
But the second aspect to consider when choosing your bathroom lights is safety. Clearly a bathroom is a wet area, and electricity and water are not the best of companions. Today however there's a very easy system in use which helps you to quickly and easily identify the type of light that's suitable for each area of your bathroom.
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.
