The fixture that changed the lighting industry. A complete rethinking of ellipsoidal technology, Source Four
is the only fixture combining the energy-saving power of the HPL lamp with the patented dichroic reflector for the coolest beam on the market. That means your gels, patterns and shutters last longer, and your performance space stays cooler.
No other light offers such optical brilliance. Source Four
's revolutionary technology gives you a clean white beam for unequaled imaging, crisp pattern projection, and a bright, even field.
Rated for up to 750 watts, the Source Four
is perfect for punching through saturated colors and performing the longest throws. Ultra-efficient for more lumens per watt: at 575 watts the Source Four
literally outshines 1000W Ellipsoidals
. And at 750 watts, well, no point comparing - there are no other fixtures in its class.
Since its founding by Fred Foster in 1975, ETC (Electronic Theatre Controls, Inc.) has become a global leader in award-winning entertainment and architectural lighting equipment. ETC's fixtures, lighting control consoles, dimmers and distribution products are the backbone of lighting systems in venues worldwide - from schools and churches, to community theaters and TV studios, to opera houses and theme parks.
Over the first decade of its history, ETC earned a reputation for sophisticated microprocessor-based lighting control consoles. By 1990, ETC had acquired Lighting Methods, Inc., a Rochester, New York-based manufacturer of entertainment dimming systems. ETC quickly became one of the largest fully-integrated entertainment lighting control manufacturers in North America, with offices in Middleton, WI; Orlando, FL; Rochester, NY; and Hollywood, CA. The next phase of growth began in 1995, when ETC acquired the lighting control division of London-based distributor ARRI GB. That same year, ETC opened an office in Hong Kong, extending its expansion into Asia. In 1997, ETC opened an office in Copenhagen, Denmark, to serve the Northern European market, and a year later opened an office in Rome, allowing greater access to Southern Europe. ETC acquired Transtechnik Lichtsysteme, Holzkirchen, Germany in 2002, widening ETC's market potential in Europe. Continuing its growth, ETC took an equity position in Avab France in 2003. In 2004, ETC acquired Dutch sine wave dimming manufacturer IES and its industrial weighing and measuring division Penko Engineering BV, both located in Veenendaal, the Netherlands. Beginning March 31, 2005, all formerly separate operations of ETC in Europe joined under the common corporate banner of ETC. ETC's new international headquarters, located in Middleton, WI (near the state capital Madison) serve as hub of global administration and manufacturing.
Through the years, ETC has gained an industry-wide reputation for outstanding service and customer support. ETC not only maintains in-house, 24-hour Technical and Customer Service staffs, but an extensive network of factory-trained, authorized field service centers.

Ellipsoidals is the colloquial term for a stage lighting instrument called the ERS (Ellipsoidal Reflector Spotlight), Profile Spotlight or Profile Spot. Other colloquial terms for the same device are Shakespeare or Leko, which is actually a brand name. Ellipsoidals are so named based on the shape of the reflector that they possess. The ellipsoidal contours capture and focus light through a cylinder containing a lens train or lens.
Ellipsoidals are of different types and come in various sizes and shapes, each having its own particular qualities. Possessing optics with similar characteristics to a typical 35 mm slide projector, they are designed for a large variety of uses in the entertainment sector. They are also the most used among all types of stage lighting devices. They are called Profile Spotlights because the beams can be customized to readily take the shape of the objectâ??s profile.
Ellipsoidals are primarily required for more intense, clearly-outlined lighting requirements that offer greater flexibility. Source Four is yet another brand name for this type of lighting instrument.
Normally, an ellipsoidal lighting unit has: an adjustable lens tube enclosing the lens or lens train; an ellipsoidal reflector; one or two Plano-convex or PC lenses; a set of bracing elements for holding the gel frames; two pairs of shutters mounted on an internally-located focal point; a metal gobo slot. The lamps in ellipsoidals are mostly rear-loaded, and either axially- or radially-mounted, with the base oriented up or down. Using the light wrong side up will result to a shorter lifespan.
