James Clarke Maxwell is referring to a point source of light.
Light which is optically modified does not fall off at this universal rate. At least not in the human scale
Professional LASER, for instance hardly falls off al all within a few kilometers

On the macro scale (above the scale of particle physics), intensity drops
off as the square of the distance for all electromagnetic energy, including
light, all the time, everywhere in the universe. It's the law. No
exceptions.
Consult James Clerk Maxwell for more details regarding this amazing
phenomenon.
