Not just that, the source has to be monochromatic (actinic) and high intensity for a fibre. Whereas for getting a natural light effect you must have spatial complex light source (non coherent, multiwavelength, scattered). Which is why no matter how you illuminate a place with artificial light, your eyes are able to easily know it's not natural.
Did I mention polarization? :P
