Sunbrick vs. LumiSuns-50 Summary

Both simulators meet IEC Class A+A+A+ standards, but the Sunbrick offers a larger illuminated area, and deeper integration for advanced research from the Python API.

The LumiSun-50 leads in lifetime, making it suitable for standard workflows where tunability and software are less critical.

What You Risk and What You Gain in Your Solar Simulator Choice

What You Risk with Less Expansive Systems (Like the LumiSun-50)

Limited Illumination Area
The LumiSun-50 provides only a 5 cm × 5 cm test area sufficient for small samples, but restrictive if your research expands to larger devices or multi-cell arrays.
No API or Advanced Integration
Basic GUI only. Without automation capabilities or instrument integration, manual setups slow down iteration and increase user variability.

What You Gain with the Sunbrick LED Solar Simulator

Large, Certified Test Area
15 cm × 15 cm of Class A+A+A+ coverage allows you to scale your research, run side-by-side samples, or move toward small-module validation.
Spectral Precision, Tunability, and Adaptability
32 independently tunable LED channels allow you to reproduce AM1.5G, AM0, or define your spectral profile, perfect for advanced research, materials development, or regulatory simulation.
Scriptable, Automated Control
Python APIs, plus Keithley 2400/2600 integration, enable repeatable test routines, synchronized IV sweeps, and streamlined long-term studies.

Less Setup, More Science
No patchwork control software. No manual toggling. The Sunbrick runs with purpose-built lab automation that adapts to how you test, not vice versa.
Proven by Top-Tier Institutions
Used by leading labs in photovoltaics, aerospace, and photochemistry because trusted, reproducible light is an essential research tool, not a luxury.
