An electrodeless fluorescent lamp having a core of magnetic material surrounded by a coil for producing a high-frequency magnetic field in a lamp vessel surrounding the core and coil. An amalgam holder is located in the vessel, in the region surrounding the core where the electric discharge is formed so that the amalgam is heated directly by the discharge. Substantially all the mercury contained in this amalgam is released quickly after the lamp is turned on, so that the light output rises rapidly. |
