A Tic-Tac-sized lightbulb that gives off as much light as a
streetlamp may offer a peek at the ultra-efficient lighting of the
future. The bulb, developed by Luxim of Sunnyvale, California, uses
plasma technology to achieve its brightness.

This paper describes the lamp and technology in greater detail:

The operating frequency range is described, but the commercially
realized product frequencies are not disclosed.

RFI from these devices may be significant; an FCC type acceptance
would provide more data, but unfortunately most self-certified
products now lack online reference data (more research needed
for this product).

Anyone here that encounters HDTVs that include this device are
encouraged to do a spectrum sweep if you have the gear.
