A Mesh Light is a polygon object that emits light into a scene. This is possible by applying a Diffuse, Universal, or Standard Surface material to the Mesh object, and then connecting a Black Body or Texture emission node to the material's Emission channel. The Mesh Light parameters can be access from the Shader editor (Figure 2) or the Light Properties Panel (Figure 3).
