   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
   The detailed technology description is accompanied by the embodiments and figures. 
   Please referring to  FIG. 3  and  FIG. 4 , a stabilizer B with brightness control for a High Intensity discharge lamp according to one embodiment of the present invention is illustrated. The stabilizer B comprises a base C, a ribbing cooler F, a circuit board G, an output E and a power input D. 
   The base C further comprises an upper base C 1  and a lower base C 2 , wherein a ribbing cooler is arranged at one side of the upper base C 1  and an output E and a power input D is arranged at the other side of the upper base C 1 . A connect pin E 1  is configured in the output E and a triple connect pin  01  is configured in the power input D. In addition, a hook portion is formed at the side of the power input and a fixating section C 3  with an opening C 4  is formed at the side of the lower base C 2 . The circuit board G is configured inside the lower base C 2 , in which a control element G 1  is configured for the use of watts-switching (adjusting). 
   One of the features of the present invention is that the power input could comprises a connect terminal D 1  having at least three terminals, wherein one of the three terminals is a positive electrode terminal, another one is a negative electrode terminal and the rest one is a power-switching terminal. The power-switching terminal is capable of adjusting power consumption (watts) by controlling the connection between the power input and the negative electrode terminal. 
   Quantities of the ribbing cooler could be one or more, which is used to cool down the stabilizer B so that a device configured with the ribbing cooler F would not over heat so as to bum down the stabilizer B. 
   A stabilizer B with brightness control for a High Intensity discharge lamp according to one embodiment of the present invention is illustrated in  FIG. 4 ,  FIG. 5  and  FIG. 6 . The HID (High Intensity Discharge) H 2  is lightened by a predefined power (watts) settled by a circuit board G. A control unit G 1  on the circuit board G is used for adjusting consumption power. Under above arrangement, a control switch  12  could correspond with the control unit G 1  on the circuit board to implement power consumption control (watts) function at will. 
   The connect terminal D 1  configured with the power terminal D on a base C has at least three terminals, wherein one of the three terminals is a positive electrode terminal, another one is a negative electrode terminal and the rest one is a power-switching terminal. The three terminals of the control switch  12  is coupled with the positive electrode terminal, the negative electrode terminal and the power-switching terminal respectively through the switch I and further extend to the control unit G 1  of the circuit board G from the power-switching terminal so as to adjust the power consumed by the HID H 2 . 
   At least one pins E 1  is configured with a output terminal E on the base C and the output terminal E is corresponding to a plugging portion on a connecting device H wherein one end of the connecting device H is extended to couple with a HID H 2  and the other side of the connecting device H is coupled with a plug H 3 . The plug H 3  is configured with a plurality of plugging portion H 1  corresponding to the pins E 1 . 
   One side of the switch I is configured with a connection portion I 1  corresponding to the power input D and the other side of the switch I is configured with a control switch I 2 . One side of the switch I is formed as a hook I 3 , which is used for coupled with the hook D 2  of the power input D, and hitched with a ring I 4 , wherein the ring I 4  is used for waterproofing. 
   For highlighting utility and non-obviousness of present invention, an analysis among the present invention and the conventional arts is disclosed as follow: 
   The disadvantages in conventional arts:
     1. One HID stabilizer provides a fixed quantity of power (watts) only so that it must be replaced when a HID is detached and causes an additional cost.   2. As mentioned above, it wastes a lot of resources and does not comply with conceptions of environmental protection.   

   The advantages of the present invention:
     1. The power consumption of the HID could be adjusted corresponding to the control element through the control switch.   2. As mentioned above, the applications of the present invention are convenient.   3. The applications of the present invention could reduce cost and be valuable in environment protection.   4. Embodiments of the present invention comply with examination under utility and obviousness.
