Abstract: The present invention relates to a light fixture comprising a head, which head comprises at least one light source, which head is carried rotatably in a yoke, which yoke rotates in relation to a base, which bases comprises bearings for the yoke, which base comprises at least a power module, which power module comprises at least one ballast circuit, which base comprises at least one controller. It is the object of the invention to achieve a fast exchange of a power module in a light source in situations of changing technical specifications of the power module. Hereby it can be achieved that the module can be exchanged very easily. This can be important in a light fixture placed high above the ground if it needs to have an electronic module exchanged. That can be important if specifications are changed after the light fixture has been placed in a thuss for operation.
