If understanding lighting seems daunting , it may help to consider it from two angles. Here are some tips to help you plan lighting and select fixtures and bulbs. Depending upon the orientation of these, and the time of day, the season, and the weather, natural light can have a gentle or harsh effect.
Natural light is primarily ambient, though it can be sufficient for daytime tasks near a window.
Try to avoid high contrasts from one area to another. Dimmer switches provide control and flexibility. Use smaller accent lights to illuminate book or display shelves, or artwork. The style of the lighting fixtures affects ambience as well as determining the amount of illumination they provide. Consider the period and style of your decor when selecting fixtures, as you would for any accessories.
