Hello,

At the turn of the century (and still today) they were/are used in 
portable high frequency X-Ray machines.

Today the circuits are more modern, but the theory is still 
there.  As an example, here is a video of
a reproduction of one of the first models of Tesla X-Ray machines:

This unit produces a hot 10" flame and occupies only 11" deep x 24" 
wide x 11" tall (with dischargers) or 4.5" tall (power supply 
only).   It weighs less than 35 pounds.

They were also used for surgically removing cysts without excessive 
bleeding (for cancer, etc.):

Traditional Spark Gap Tesla Coils were used for both these instances 
from the 1890s up until the 1940s.   Even up until recently some 
surgical devices still use spark gaps inside.  The control of cutting 
and coagulating tissues is much easier performed by a spark gap than 
electronics. . .Anyone who has received an rf burn will know 
why!  With spark gap circuits,  you can control the dehydration and 
cooking of tissues...with electronic circuits its normally arc and 
"OUCH", with a nasty white reminder left where it hit!

As for wireless lights, there was a company in 1939 called SunKraft 
that made a cold-quartz UV Ozone lamp that had a wireless bulb.  It 
ran from a high frequency radio tube circuit in the base.

These can be found normally for around $35!
