SurfaceLight

A glowing panel. Light pours out of one face of a part, like a ceiling light or a bright screen, with soft shadows when path traced.

A SurfaceLight shines out of one Face of the Part it sits directly under, from the middle of that face, spread over Angle degrees (90 by default) and out to its Range (16 by default). In Rendered it is path traced, and its shadows soften with the size of the face. Insert > Light > Ceiling panel is one shining down (Face Bottom).
