It is essential to utilize different types of light for different areas.  Just because you have found that perfect light you dreamed of doesn't mean it will solve any lighting issues you may have.  For instance in the kitchen the light that is used for safety at night, or preparing food is not the same type of light you would use for gatherings and entertaining.  The light you use to read would not be used as general light for a room.  These are some factors that need to be taking into consideration when designing a room.  When you do you will use three types of light, General, Accent, and Task lighting.  For instance in a kitchen you have general lighting through recessed lights and ceiling lights.  Your task lighting will come from under cabinet lights.  These lights help with the task of preparing food.  Finally some ambient light would be used to accent china cabinets, glass cabinets, etc.  With these three different types of light your kitchen atmosphere is complete.
