Projector Bulb (575 Watt)
Proudly Using Ushio HPL Lamps
USHIO developed the HPL lamps based upon ETC design ideas in 1994, consistently adhering to the original design specifications and minimum parametric variations, such as filament position and spacing, to optimize the output of the Source Four fixture.
USHIO continually worked to improve its HPL design, and in 2002 released the HPL+ with improved filament spacing for increased light distribution as well as a ceramic base for better insulating performance. The Super Long Life (average life of 3000 hours) HPL lamp was developed in 2016 to extend the product life cycle to the education market and others that had not yet converted to LED. ISO9001 manufacturing standards and strict quality control has ensured a consistent product from USHIO over the past 25 years of HPL production.
USHIO HPL Lamps continue to develop and provide a halogen lamp that has traditional color rendering properties as the halogen-to-LED global transition accelerates. Major halogen lamp manufacturers around world are exiting the halogen lamp business, but USHIO is committed to be the top halogen lamp manufacturer as long as there is a need from a market.

The ellipsoidal fixture that changed the lighting industry
There’s only one Source Four – the ellipsoidal fixture that changed the lighting industry. Source Four combines the energy-saving power of the patented HPL lamp, with a dichroic reflector and optical-quality lenses, for the coolest beam on the market. That means your gels, patterns and shutters last longer and your performance space stays cooler.
About the Source Four
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. The EDLT lens tube option for 19º, 26º, 36º and 50º field angles makes the Source Four even better for ultra-crisp, high-contrast gobo projections.
Source Four Zoom
Maximum brightness, maximum field-angle flexibility. With Source Four® Zoom you only need one fixture for a variety of field angles.
