“Use emissive for static lighting” has to be enabled on the mesh with the emissive material. Then the emissive will be used in the lightmass calculation which affects all static meshes in the scene. Afterwards you have to rebuild lighting (or rebuild the whole level). Do you have it set up this way?
For the solution with point lights: Just place regular point lights and increase the “source radius” and “source length”. The light still emits as a point light, but specular reflections will be an approximation of an arealight with the specified dimensions.
