Abstract
A bulb for an electrodeless lamp system uses Sn or halogenide of the Sn as a primary bulb fill for obtaining continued spectrum when it is discharged, and the halogenide of the Sn is SnBr2. Therefore, high photoefficiency and superior color rendering can be obtained, and less ultraviolet ray than that of sulfur is radiated and warm feeling can be obtained visually.
