They are already being used in Panasonic LiFi rear-projection HDTVs where they've replaced the usual halogen or xenon arc projector bulb.
Instead of a glowing hot filament or electrodes passing high voltage through xenon gas; it uses RF energy (basically the same as microwaves) to excite the gases inside the capsule. The gases heat up and give off light.
The technique is like microwave powered sulfur lamp. It uses electromagnetic induction at high frequencies rather than current flowing between electrodes stuck in the plasma.
