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.
