ETC/Elec Theatre Controls 450
Source Four 50° Ellipsoidal in Black

OUR PART #  S4-50


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 ellipsodials. And at 750 watts, well, no point comparing - there are no other fixtures in its class.

ETC 450 Features:

  • 50° field angle
  • Rated up to 750W
  • Super-efficient HPL lamp
  • Faceted dichroic reflector removes 90% of IR heat from beam
  • Interchangeable lens tubes
  • Rotating barrel +/-25%
  • Three-plane stainless-steel shutter blade assembly
  • Tool-free lamp adjustment
  • Insulated rear handle
  • Rugged die-cast aluminum construction
  • Supports Dimmer Doubling
  • The Source Four is UL and CUL listed, CE compliant, TUV approved and GS marked

NOTE: Lamp and Connector NOT Included.
