[RFI] New bulb? Acandescence in Finallly bulb

[Charles Coldwell]

>From their blog:

"Induction lighting starts with an insulated copper coil wrapped
around a ferrite core. High frequency power from an electronic ballast
is sent through the coil to produce a magnetic field which initiates
and sustains a steady-state plasma. The plasma generates UV light
which is converted to visible light when it hits a phosphor coating on
the inside of the bulb."

That sounds a lot like a conventional fluorescent light if you
substitute "mercury vapor" for "plasma", except that instead of
putting electrode in the tube they induce a voltage with a coil.
Notably, they don't specify the chemical nature of their plasma.
