Steradian

Steradian (simbol: sr) atau squared radian merupakan salah satu besaran dalam Sistem Internasional (SI) untuk sudut ruang (solid angle). Steradian digunakan dalam ruang tiga dimensi dan fungsi analogi. Nama steradian merupakan campuran dari bahasa Yunani 'Stereos' yang berarti solid dan bahasa Latin 'Radius' yang berarti jarak/jarak gelombang.

Intensity is emitted power per steradian (and maybe Hz if it is spectral intensity), while irradiance (of confused with intensity) is received per unit area. So the sphere emits over an area of $4\pi r^2$, while the disk receives energy over an area of $\pi r^2$...which is why you lose a factor of 4.
