White LEDs based on blue + phosphor have an aging problem -
they go green as the phosphor ages. White LED based on RGB are
(by definition) three narrow band illuminants, and probably
also change white point as they age (although this could be
compensated for). Creating a high quality (ie. like sunlight)
illuminant using LED's would seem to be non-trivial.
