Basics
- A type of light that is similar to a gas discharge lamp, or plasma lamp (neon light), but uses microwaves instead of electrodes
- These thus have a high brightness, yet also a long lifespan
- The main issues have been magnetron life, and how to keep the bulb from overheating (Some models rotate the bulb, circularlly polarized light may work according to some studies)
- Not for small applications, but could be used for projector lights, stage lights, and other high brightness applications

- OLED / Organic field-effect transistor (May be similar in an appropriate materials context, but less complex in use/installation, albeit with a trade off for manufacturing complexity)
