The average living room needs between 1,500 and 3,000 lumens of ambient lighting. Living room areas dedicated to reading and other tasks require at least 400 lumens.
A well-lit living room contains multiple sources of lighting, including ambient lighting and task lighting. Ambient lighting illuminates the entire room, usually with ceiling fixtures and track lighting. Lamps are an example of task lighting, which provides light that is bright enough to prevent eyestrain.
The brightness of light is measured in lumens. Bulb manufacturers list lumens on the Lighting Facts label. Each label also lists energy cost, lifespan of the bulb and the light’s appearance, which ranges from a warm or yellowish appearance to a cold or bluish appearance.
