With all the task lighting in kitchens, a general background light may not be needed. For example, well placed recessed lights over the counters may provide ample general light. On the other hand, fluorescent lights mounted under the cabinets may leave the kitchen in need of more general light. If installed, the general light should use a fluorescent lamp and have a separate switch. It could be a surface-mounted fixture, a "cove" light mounted on top of the cabinets or a luminous ceiling.
Lighting Controls
Imagine that you had only one light switch for the whole house. That would force you to use too much light in the wrong places. Good lighting controls allow you to put the right amount of light in the right places.
