[RFI] New bulb? Acandescence in Finallly bulb

[KD7JYK DM09]

Speaking of funky bulbs...

About 25 years ago I read an article about light tubes used in a museum 
somewhere.  They were RF in nature, operating frequency was 27.12 MHz if I 
recall correctly.  As I recall there was an oscillator at one end of a long 
tube, not sure how it coupled to whatever was in the tube, guessing it was 
some sort of plasma device.  Fast forward to about 5 years ago and I saw one 
of the oscillators for sale on ebay.  Guessing it was priced too high or I'd 
own it.

Anyone seen or know of such a lamp?  I'd like to find an RF source for such 
a lamp to play with.
