Non-rotating electrodeless lamp containing molecular fill

1. Technical Field An electrodeless lamp includes a stationary bulb () containing a fill for producing a discharge, the fill has a primary radiating material which ordinarily produces an unstable discharge in the absence of bulb rotation. The fill further includes an alkali metal in an amount sufficient to stabilize the discharge without bulb rotation. The alkali metal may be, for example, cesium bromide. Preferably, the fill is excited by a non-stationary electric field (E, E) such as, for example, a circular polarized electric field.
