The ETC Source Four (Source 4) Leko features a standard Source Four ellipsoidal head and a lens tube of your choosing- 19, 26, 36, or 50 degree. The Source Four is the fixture that changed the lighting industry. It combines the energy saving power of the HPL lamp with a dichroic reflector and optical quality lenses. These features combine to make the coolest beam available in an ellipoidal- meaning gels, patterns, and shutters last longer and your performance space stays cooler. Source Four fixtures are shipped brand new with a c-clamp, color frame, and a slot for either a drop-in iris or motorized pattern device. Three-foot, three-wire Teflon leads with bare ends encased in black fiberglass tubing are shipped as standard.
