The NuArc PM-78 is a high-intensity 6000-watt metal halide lamp, engineered for precision in screen printing and platemaking applications. When installed in an exposure unit like the NuArc Tri-Light 6K, the lamp emits a powerful, UV-rich spectrum optimized for rapid and even emulsion exposure.As the lamp ignites, a brilliant arc forms between the internal electrodes, filling the chamber with uniform ultraviolet light. This controlled light output ensures sharp, detailed stencils and consistent exposure results across large-format screens. The ceramic bases provide secure connections and heat resistance during extended use, while the robust quartz envelope protects the internal arc tube under high operating temperatures.Whether in a high-volume print shop or a specialized graphics lab, the PM-78 delivers the performance, reliability, and clarity professionals depend on.
