Fundamentals of Light
Visual comfort is measured by illumination levels and distribution. This includes not only the brightness of light sources, but also the colors in the light, and how well light is spread around spaces. The goal is to illuminate tasks without using too much energy or causing glare. Good lighting design achieves visual comfort by modeling and simulating daylight and artificial light.

Measuring Light Levels
Good lighting design requires understanding the metrics. Learn about basic metrics like luminance and illuminance.
Light Distribution & Glare
Light needs to be well distributed for true visual comfort. Glare is caused when areas bright areas are next to dark areas.
Colors of Light
For good visual comfort, light needs to have the right color and quality. Light can feel cool or warm. This is quantified by the "color temperature" and measured in degrees Kelvin.Comments
