The (compact) fluorescent lamp is basically a lowpressure
mercury gas discharge lamp with the
inner surface of the discharge tube coated with
a mixture of fluorescent compounds — called
phosphors — that convert the invisible ultraviolet
radiation emitted by the mercury discharge into
visible radiation.
With a broad range of phosphors
available, the lamps are available in a wide range
of colours and colour renderings, and are mostly
used for general lighting.
so when refracted through prism it will split into its constituent colours.
