The JS120V-750WX HPL+ Compact Filament Halogen Lamp from Ushio is a 750W tungsten halogen, 120V and comes in a 6-pack. It has been redesigned to be the most powerful HPL ever. It's ultra-compact filament geometry now improves the optical efficiency of the 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. This improvement partnered with the optics of the Source Four, generate ultimate axial and radial light distribution and optical system efficiency. The Source Four's precise optics demand precisely engineered lamps. Ushio has responded to the Source Four's need for a reduced geometry filament, and has done so with quality manufacturing standards. Performance you can measure, quality you can count on, variety of lamp types, and innovative design for your theatrical needs.
