Perfectlight Technology offers the following xenon lamp light sources:
PLS-FX300HU High Uniformity Xenon Lamp Light Source, Microsolar 300 Xenon Lamp Light Source, PLS-SXE 300E/300EUV Xenon Lamp Light Source, PLS-SXE 300+/UV Xenon Lamp Light Source, CHF-XM Series Xenon Lamp Light Source, and new product: PLS-SME300E H1 Xenon Lamp Light Source, PLS-ILS Integrated Spherical Xenon Lamp Light Source.
Under constant voltage, we generally adjust the electrical power of the xenon lamp light source by varying the current of the xenon lamp light source, thereby achieving the adjustment of the xenon lamp light source's optical power. (Changing the distance from the light source to the target can also alter the optical power).

Methods for Adjusting Xenon Lamp Light Source Optical Power
The previous question addressed how to control the optical power of the xenon lamp by adjusting the current. However, to determine the specific light power density value, you need to measure it with a professional light power meter.

User Guide for PL-MW2000 High-Power Light Power Meter
Variations in measurements taken with a light power meter due to different positions are often because some models of xenon lamp light sources do not produce uniform light spots. For non-uniform light spots, using a single area within the spot to represent the light power density can result in significant errors.
To obtain precise light power density values in such cases, you need to use the five-point method.

Five-Point Method for Measuring Light Power Density, with Detailed Steps
Both Microsolar 300 and PLS-FX300HU light sources have built-in optical feedback systems. When you activate the constant irradiance output mode, the xenon lamp light source detects its output irradiance value in real-time and adjusts it automatically to maintain the average irradiance within the set value over a unit of time. This enhances the precision of light exposure experiments.
As a result, with increasing reaction time, when the bulb's brightness decreases, its output irradiance drops. To compensate for the decreased irradiance, the xenon lamp light source automatically increases the current. Therefore, you will observe an automatic increase in the current value.
