Xenon lamps serve as the primary external energy source in photochemical experiments, and their energy intensity has a significant impact on experimental results. For the same xenon lamp source under the same electrical power conditions, factors such as the distance of irradiation, applied current, the model of used filters, the model of liquid filters, window material, and bulb usage time all contribute to significant differences in both optical power and spectral shape. Therefore, when conducting experiments using xenon lamp sources, experimenters need to use certified or calibrated optical power meters to measure and record the actual optical power or optical power density values for each experiment. Additionally, optical power density values are involved in the calculation of important metrics such as STH, AQY, IPCE, and ABPE. To ensure data accuracy, it's crucial to use xenon lamp sources and optical power meters correctly.
