The PL-X300D high-energy xenon lamp light source for drug trials is a research grade light source designed for photocatalytic applications. A 300W high-voltage short arc xenon lamp is installed inside the light source, which forms arc discharge under high-frequency and high-voltage excitation. High voltage short arc spherical xenon lamp is a point light source with a very small emission point. When ignited, it emits strong and stable light waves, with a strong continuous spectrum from ultraviolet to near-infrared. The visible light color is extremely similar to sunlight, with high energy density and stable output. It is widely used in photocatalysis, industrial catalysis, photocatalytic hydrogen production, photochemical catalysis, photochemical synthesis, and photocatalytic degradation of pollutants
