Class A+ Light for Research That Demands Accuracy
Precise, repeatable, full-spectrum light: whatever your application.
Every comparison starts with specs, but the best instruments prove themselves in the data. G2V’s Sunbrick is Class A+A+A+ rated to IEC60904-9:2020, covering 350 nm – 1200 nm across 32 tunable LED channels, with spatial non-uniformity ≤ 0.8% and short-term instability under 0.025%. See how it stacks up.
The most accurate solar spectrum available in an LED simulator.
The Sunbrick AM1.5G spectral output covers 350-1200 nm across 32 tunable LED channels, exceeding IEC60904-9:2020 Class A+ requirements and the ASTM E927 standard.
Consistent, repeatable light across every millimetre of your sample.
Spatial non-uniformity of ≤1% across a 10×10 cm Class A+ illumination area – with Class A uniformity extending to 15×15 cm for larger samples.
From power-on to publication-ready data in seconds.
Short-term temporal instability under 0.25% from a 2-second cold start, with long-term instability below 1% over a rated 25,000-hour lifetime.
Top-tier labs in aerospace, photovoltaics, and materials science are turning to the G2V Sunbrick because they need more than just light; they need control – bulky Xenon systems with drifting spectra and manual control don’t cut it.
Whether you’re:
Validating next-gen solar cell performance
Simulating real-world solar conditions across custom spectra
Or automating precise, long-duration optical tests
The Sunbrick delivers Engineered Sunlight™ without the optical benches, bulb changes, or setup headaches. Just stable, repeatable, programmable light. Wherever and whenever you need it.
