geo/AreaLight
A rectangular panel light, like a softbox or a lit window.
Lights
A physically based rectangular emitter (linearly transformed cosines). The panel lies in the node's local plane and shines along its forward axis; width and height set its world size. A larger panel gives broader, softer highlights and gentler falloff. Area lights do not cast shadows yet.
