USHIO's high performance HPL+ lamp is designed to be the most powerful HPL ever. Its ultra-compact filament geometry now improves the optical efficiency of your ETC Source Four fixtures.

Previously, design of the HPL lamp was limited to larger filament dimensions than USHIO's 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 generates ultimate axial and radial light distribution and optical system efficiency.

Product Features:

• Integral heat sink base
• More fixture light output using less electrical energy
• Low seal temperature
• High efficiency (28.5 lumens per watt average)
