The ETC Source Four is the ellipsoidal that changed theatrical lighting, here in the 36° field angle in black. The patented HPL lamp, faceted dichroic reflector and optical-quality lenses produce a clean white beam with crisp pattern projection and a bright, even field, while removing 90% of infrared heat from the beam so gels, gobos and shutters last longer. Rated up to 750 W, it punches through saturated colours and handles long throws that leave conventional 1 kW ellipsoidals behind.
