Source Four - the ellipsoidal spotlight that changed the lighting industry. Smaller, lighter and much brighter than conventional 1000W ellipsoidals, Source Four sets the standard.
Source Four's clean white beam means excellent imaging, for crisp pattern projection and smooth washes. Source Four's interchangeable lens tubes fit any application, and its rotating barrel puts your cuts just where you need them.
Source Four's cool beam technology means gobos and shutters last longer and performers are more comfortable on stage.
Source Four is economical. Easy focusing and tool-free lamp adjustment save on valuable load in time, and energy and air conditioning costs are cut by over 40%.
And ETC's patented Dimmer Doubling technology can reduce dimmer and wiring costs by up to 50%. Source Four - the industry standard ellipsoidal from ETC.
