The best lighting for grooming comes from the side, not overhead. Lights above the mirror cause a shadow on the face, making it difficult to groom and put on make up evenly. Instead, put sconces on each side of the mirror to cast an even amount of light across the face. A rule of thumb is to put sconces 60"-66" from the floor and 30"-36" apart.
I have included some images to help give some ideas.

Here are some fabulous sconces I found in a wide variety of prices.
Add other lighting as needed, such as recess lighting in the tub/shower area and a ceiling light for ambient light. To gain total control over your lighting, install a dimmer.
Next time you are in a dressing room, pay attention to where the lighting is placed. If it is along the side of the mirror, I bet it will make you look better and therefore buy more clothes.
Don't forget....let your light shine.
