A middle output electrodeless lighting system comprising: a resonator having a certain inner space and adapted to form a resonance mode by shielding a discharge of microwaves applied therein to the exterior and to allow a discharge of light generated to the exterior; an electrodeless bulb including a light emitting portion positioned in the inner space of the resonator to emit (generate) light upon plasmarizing light emitting materials filled therein by the microwaves applied to the resonator, and a supporting member to support the light emitting portion thus to allow the light emitting portion to be arranged up to a certain height in the inner space of the resonator; and an initial lighting unit disposed at one side of the inner space of the resonator to enhance concentration of microwaves toward the electrodeless bulb so as to stabilize an initial lighting of the electrodeless bulb.
