Introducing the revamped Ushio HPL+ lamp, now the most powerful HPL available. With its newly designed ultra-compact filament, this lamp enhances the optical efficiency of your ETC Source Four™ fixtures, delivering up to 20% more lumens—meaning you get more light without changing the fixture.

Unlike competing HPL lamps, which have larger filament dimensions, Ushio’s innovative 6.0mm x 9.5mm filament design was developed in collaboration with ETC engineers. This compact profile optimizes light distribution, maximizing both axial and radial efficiency.

The precise optics of the Source Four require equally precise lamp engineering. Ushio has addressed this need by creating a reduced geometry filament that meets high manufacturing standards. Enjoy measurable performance, reliable quality, a range of lamp types, and cutting-edge design tailored for your theatrical needs.
