Lighting Source: Layer your light sources: To add functionality and dimension, shoot for three light sources per room: ambient, task and accent lighting, especially in bedrooms. Ambient provides a main source of lighting, like a chandelier or ceiling fan. “When you have a big light fixture, consider your ceiling height,” says Brown. “If you have an 8-foot ceiling height or lower, you probably don’t need to go super big, but if you’re looking at a 9- or 10-foot ceiling, you have a lot more room for that bigger fixture.” Task lighting, on the other hand, helps perform specific activities such as reading, cooking or working. Accent lights are fun or beautiful fixtures, such as pendant lights or lamps, that really add to the mood and design of the room.
