There are three main layers to lighting: ambient, task, & accent. Ambient lighting is foundational and general illumination that allows you to see your surroundings. Think recessed lighting, flush or semi-flush mounts, or ceiling fans with lights.
Task lighting applies to any room and supplies an ample amount of light for everday tasks such as an office desk lamp, undercabinet lighting in the kitchen, or a bedside lamp. Keep in mind that brightness an adjustability are key.
The third layer, accent lighting, serves as jewelry for your home, with the focus being more presentation than function. There are a variety of options including shelf uplighting, sparkling chandeliers, and architectural centerpieces. Go crazy & highlight what you love!
