Kitchens and baths really need great lighting in order to be a success. Don't make the mistake of leaving this detail out of your plans until it's too late. So before you finalize everything in the planning stage, make sure that you have taken these three things into account:
1) Where and what type of GENERAL lighting do you want in the kitchen, i.e. - recessed cans, pendants, etc...
2) What type of TASK lighting do you need to perform your daily tasks such as meal preparation, coffee making, and cleaning?
3) What type of ACCENT lighting do you want, if any at all? This can include interior cabinet lights, cove lighting, etc...
4) What kind of bulbs do you want to use? Do you want halogen, xenon, LED, or flourescent undercabinet lights? What kind of bulb do you want to use for your recessed can lights and fixtures?
GENERAL LIGHTING
The first thing to do is to gauge how much natural light from windows and skylights is available. For instance, during the planning phase of my own kitchen remodel in the summer of 2011, we decided that there was just not enough natural light in the kitchen. Our kitchen is situated in the northeast corner of the house (read: least amount of sunlight) and the two windows to the kitchen were shaded by the roof over our covered deck. The first thing we did was add two skylights to the roof to increase the amount of natural light. It was a bit costly up front, but as a result, we never have to turn our lights on during the day. Over the life of our stay in this home, we think the energy savings from not running lights during the day will effectively pay for the two skylights.
