Lighting is important in the kitchen. Not only does it create a warm homey ambiance, it also provides necessary illumination while preparing and cooking meals. If you are planning to change the lighting of the kitchen, the best is to consult a professional. If he or she can make a house call, the better. But if you decide to take on the project yourself, remember to bring a picture and the exact dimensions (floor to ceiling, space measurements, etc.) of your kitchen. When choosing bulbs and lighting fixtures, use the same color bulbs so that there would be equal tone and intensity throughout the kitchen.
