The Source Four Jr Zoom 25 to 50° Ellipsoidal Lighting Fixture with Dimmer (Twist Lock Connector, Black) from ETC features an optimized optical system for efficient photometric performance. It comes equipped with two bi-convex lenses and a faceted borosilicate reflector with dichroic cold mirror coating. The faceted borosilicate reflector removes over 90% of infrared radiation (heat) and over 95% of visible light. Rated up to 575W, the Source Four Jr Zoom comes with an HPL, a compact tungsten filament contained in a krypton-filled quartz envelope. The patented filament geometry provides efficient light collection and transmission, whereas the integral die-cast aluminum acts as a heatsink for the lamp base.
