A xenon lamp generates light by striking an electric arc through high-pressure xenon gas. Its emission spans continuously from the ultraviolet all the way into the near-infrared, and across the visible–near-IR region it closely approximates black-body radiation—making it an excellent "artificial sun." That is why xenon light sources have become the default artificial solar source for photocalysis, photochemical synthesis, photodegradation, and photoelectrochemistry. Unlike mercury lamps, which emit only at a few sharp characteristic wavelengths, a xenon lamp has no dominant spectral lines and therefore reproduces a far more realistic solar irradiance environment.
300W is the most common power class for benchtop photochemical systems, striking a balance between optical power, footprint, and cooling cost. Perfectlight's PLS-SXE300 series offers several configurations for different experiments: the PLS-SXE300+/UV delivers stronger UV energy, ideal for UV-driven photocatalytic systems; the PLS-SXE300E is a more economical configuration; and the PLS-SXE300D pairs a constant-current power supply with an optimized thermal structure for long, continuous irradiation. At its core, selection is about matching spectrum, optical power, and stability.
| Source type | Spectral character | Typical use case |
|---|---|---|
| Xenon light source | Continuous full spectrum, close to sunlight | Full-spectrum photocatalysis, solar simulation |
| Mercury lamp | Strong sharp lines (365/405 nm, etc.) | Narrow-band experiments at specific wavelengths |
| LED light source | Narrow monochromatic band, energy-efficient, long life | Monochromatic excitation, wavelength-tunable studies |
These three are complementary rather than interchangeable: use xenon for full-spectrum screening, LED for precise monochromatic work, and mercury for specific spectral lines.

Not exactly. A xenon light source is the emitting device with a continuous, sun-like spectrum. A solar simulator is a system built around a xenon (or other) core plus homogenizing and filtering optics that reproduces the AM1.5G standard solar spectrum—placing more emphasis on spectral match and uniformity.
300W is the most common class for benchtop photochemical systems, balancing optical power and cooling. Whether it is enough depends on sample area and required irradiance; calibrate at the sample position with a light power meter rather than trusting the wattage.
Use xenon or a solar simulator for full-spectrum or sun-like work; use LED for monochromatic excitation, wavelength scanning, or long stable runs. They are complementary—mature labs often run both.
