DESCRIPTION

   The high Frequency Electrodeless Dicharge(HFED) lamp is a technological advance in the 21th century lighting source. It generates light by combining the advantages of conventional fluorescence lamp with high frequency magnetic field; conducted the operating principle is that a 2.65MHZ HF magnetic field is used to activate inert gas which then collides with fluorescence material coated in inner bulb wall to produce visible light. This process does not involve any electrode or filament; hence life of the lamps can be increased significantly to at least 60,000hours.
