A system and a method, capable of executing a process operation by using a plurality of applications, are provided. The combination can be different engines with different injectors or the same engine or the same injector but with different characteristics for the engine and injector. The mounting substrate for the LEDs has a surface that is exposed to the exterior of the enclosure for transmitting heat from the plurality of LEDs and dissipating heat to the ambient environment. The fins of the same side are parallel to each other. Transmission of successive arrays may coincide with successive occurrences during the course of a live event.
