models in the PS Range, all featuring elegantly designed extruded aluminum housings, making them lightweight and easy to install. All units use a multifaceted dichroic coated reflector that keeps the beam cool enough for gel filters to be used and ensures maximum light output and a very uniform light distribution. Four beam shaper blades are fitted to each unit and the beam may be further modified by moving the focus to change from a hard edged projection to a general wash effect. Changing the beam angles is as simple as changing the front lens. Note, these projectors are designed for, and should only be used with the GKV 600W lamp.
