An electrodeless discharge lamp has a thinner wall portion located proximate a position of high applied power. Since the heat capacity of the thinner wall portion is smaller then the remainder of the bulb wall, the thinner wall portion cools faster when the lamp power is turned off, and the condensable part of the fill tends to condense at this bulb wall portion. When the power is turned on again, since the thinner wall portion is located at a position of high power application, the fill is available in such region to be evaporated, thereby resulting in more rapid starting.
