There are a few types of lighting to consider for a kitchen mentioned here in no particular order of preference. Central lighting of which the fluorescent fitting is the most popular due to the amount of light that is omitted and the ease of keeping the fitting clean, including down lighters which can be positioned and angled to create ample light with the added benefit of creating ambiance especially when used in conjunction with a dimmer switch. The advantage of a single light fitting is the ease of cleaning the fitting but the down side of a single central fitting is that it will cast a shadow over your work since the light source will be behind you in most applications. This can be overcome by positioning down lighters above the work area or angled towards the working area.
Good general lighting consists of achieving a low level of light all through the living area. This consists of ceiling fixtures of all kinds. From the standard central light to a completely illuminated ceiling, lighted valances, cornice, soffit or wall lighting, recessed fixtures in ceilings or floors, or nicely placed portable lights like table lamps and up lights will all bounce light of ceilings and walls and create a dramatic element when employed properly.
