The ICS is a constant current (CC) source that limits the necessary current to drive the light safely. Without a CC source like an ICS 2 the light would vary in brightness and could be damaged by unregulated currents. The ICS 2 drives LED illuminators at much higher efficiencies and accurate current regulation when compared to traditional “24V” systems. It is the best choice for most lighting applications that require constant (CW) illumination.
