Task lighting is for as the name implies working light. Some forms of task lighting are desk lamps, counter lights, and table light. These lights are planned and placed where there is work to be done. Next there is lighting for cabinets and underneath shelves. For lighting pictures, art, or any other item you want to highlight on walls use track lighting, recessed wall washers, or recessed adjustable fixtures. Accent lighting is the artistic type of lighting used for visual effect and mood. Artistic lighting is lighting such as spot lighting, sconce lighting, up lighting, and down lighting. For lighting pictures, art, or any other item you want to highlight on walls use track lighting, recessed wall washers, or recessed adjustable fixtures. Creating balance in lighting is an art form in itself. There are knowledgeable lighting specialists that can give you advice on the different types of lighting. The American Lighting Association offers free pamphlets, newsletters, and advice. Lighting is very technical because certain lights are for special uses and when considering light you have to take into account what you are lighting and how much light is too much or just right for the space.
