Different sorts of lights have different uses. At college I was taught that fluorescents imitate the Sun's light spectrum more accurately than filament light bulbs. We'd need to produce the correct sort of spectrum if we ever need to grow the plants we have available nowadays in outer space habitats or other planets. On a more localised basis, different sorts of scenarios on Earth dictate different sorts of light bulb light as well. If a type of light bulb economically out competes others in mass production, the others still have uses

So much carbon made in white dwarf and other star remnants, lighting these new carbon augmented bulbs up from the ashes. Star remnants are also imbued with lots of oxygen. Us oxygen breathing carbon based lifeforms can truly be said to be made out of star dust.

I'm not sure if the carbon we are made out of is actually from white dwarfs or rather from exploded stars but carbon has so much to do with our lives, extending now into lighting. If these new bulbs were to be produced cheaper, would LEDs be out of business? A very big investment in the mass production of one or the other would take business in that direction.
