Comparison
The Ossila LED simulator offers a budget-friendly entry into solar simulation but trades off spectral depth, area size, customization and price/cm^2.
See how the Sunbrick compares when your research needs full-spectrum Class A+A+A+ output from 350 nm upward with true tunability and long-term testing stability.
| Feature | G2V Sunbrick LED Solar Simulator | Ossila (G2009B2) LED Solar Simulator | Questions To Ask Yourself |
|---|---|---|---|
| Area of Illumination - Class A | 150 mm x 150mm up to modular 3x2 array sizes | 15 mm diameter (Circular spot) | Will my Device Under Test (DUT) increase in size as my research progresses? |
| Area of Illumination - Class A+ | 100 mm x 100mm up to modular array sizes | TODO build field | TODO build field |
| Spectral Range | 350 nm – 1200 nm | 350 nm -1000 nm | Do I need UV photons starting at 300 nm or NIR coverage beyond 1100 nm, or will the power in these areas be sufficient? |
| Spectral Control | Yes - 32 channels full spectrum control | Yes - 12 Channels | Will I need to simulate AM1.5G, AM0, or custom conditions? |
| IEC 60904-9 Compliance | Class A+A+A+ | Class AAA | Do I need certified, high-accuracy performance across all IEC categories? What problems will I have with lower Class uniformity performance? |
| Spectral Coverage | <98% | TODO | 100% is ideal |
| Spectral Deviation | <27% | TODO | 0% is ideal. How closely does the spectrum need to match real sunlight for my application? |
| Spectral Match | < ±9% | A | How much spectral mismatch can my application tolerate before it affects measurement accuracy or material performance? |
| Long-Term Temporal Stability | <1% | A | How sensitive are my experiments to light stability over time? |
| Spatial Uniformity | <0.8% | A | Do I need consistent irradiance over the full sample surface? Could spatial variation compromise my data? |
| Lifetime | 25,000+ hours | ~10,000 hours | How much downtime or recurring cost can I afford? What are the cost of bulb replacements? How many bulbs per year will I need? |
| Software & API | Yes - Modern GUI and Python API included | Ossila Solar Simulator Console software | Will I need automation, scripting, or lab instrument integration? Will I need to run scripts across multiple instruments? |
| Maintenance | No consumables; No alignment needed; | Low maintenance | How much downtime or recurring cost can I afford? What are the cost of bulb replacements? How many bulbs per year will I need? |
| System Footprint | 33cm x 33 cm x 50 cm. Both base and illumination head are 25 cm tall | TODO build field | TODO build field - Does my setup require space efficiency? |
| Price Point | <$100/cm² | ~ 169.00/cm² | Does the price reflect full system capability and long-term value? Will I need to upgrade or maintain later? |

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.
