Ushio HPL-550/77X+ 550W Lamp
The high performance USHIO HPL+ lamp has been redesigned to be the most powerful HPL ever. It's ultra-compact filament geometry now improves the optical efficiency of your ETC Source Four™ fixtures to produce up to 20% more fixture lumens. That's up to 20% more light from the same fixture as compared to the old lamp design.
Competing HPL lamp products are limited to larger filament dimensions than the USHIO HPL geometry. Working in close cooperation with ETC's engineers, USHIO has matched the "innovation" of the Source Four fixture by making a more compact (6.0mm x 9.5mm) filament profile. This improvement partnered with the optics of the Source Four, generate ultimate axial and radial light distribution and optical system efficiency.
