The ETC Source 4WRD is a white-light LED retrofit module that converts a full-size Source Four ellipsoidal from tungsten to LED quickly, without special tools. Designed to preserve the fixture's original optical performance and accessory compatibility, it provides a practical option for rental situations where reliable, repeatable operation and rapid turnover are important.

Key Features

• Straightforward retrofit: Installs in seconds to a Source Four ellipsoidal, no special tools required.
• Original optics and accessories retained: Uses the same lenses, gobos, shutters, and accessories as a standard Source Four fixture.
• High output, lower power: Comparable brightness to a 575-watt extended life HPL lamp while using about 70 percent less power.
• Reduced maintenance: LED technology removes the need for frequent re-lamping, simplifying turnover between rentals.

Use Cases

• Theatre and touring: Fast changeovers and reduced power draw are beneficial for productions moving between venues or requiring quick rigging.
• Corporate and event rentals: Consistent white-light performance and familiar beam characteristics make it suitable for conferences, presentations, and rental houses serving diverse clients.
• Long-run productions: Reduced lamp replacement and lower heat output help lower operating overhead during extended engagements.
