There is a similar post on Reddit, and someone says “This can be solved by checking the emissive light source option in the details tab of the static mesh you are using as the light.”

Does anyone know why emissive materials in Lumen only light the environment to a certain distance and how to increase the distance? : r/unrealengine (reddit.com)
