EVSUN Research & Certificates
Effectiveness of EVLN technology confirmed in independent laboratories on three continents. All results available as full PDF reports.
How We Conduct Testing
Independent laboratory
All tests commissioned to external laboratories — no manufacturer influence on results.
Standardised test conditions
Test chamber, controlled temperature (~25°C), humidity, exposure time and distance from source.
Control and test samples
Each test includes a control group without light exposure — comparative results.
Full documentation
PDF report with raw data, test conditions, laboratory signature and test date.
Applied test standards
Results Summary
All tests conducted under defined laboratory conditions. Real-world results may vary depending on installation specifics.

EVLN vs. Typical Photocatalytic Technologies
Not all claims are equal. Compare EVLN's documented results against typical industry claims.
| Parameter | EVLN (EVSUN) | Typical Photocatalytic |
|---|---|---|
| S. aureus effectiveness | 99.71% in 6h (TÜV SÜD) | ~90% in 24h (no witness test) |
| Independent verification | TÜV SÜD Witness Test | Often internal testing |
| Number of laboratories | 5 in 3 countries | 1–2 |
| UV emission | None (visible spectrum) | Often requires UV |
| PL hygiene certificate | PZH hygiene attestation | Rarely |
| Document availability | Full PDFs available | Limited |
What the Tests Measure — and What They Don't
All microbiological test results were obtained under controlled laboratory conditions: a closed test chamber, defined temperature (~25°C), humidity and exposure time. These are not measurements in a real-use environment.
Real-world effectiveness depends on: fixture mounting height, distance from most exposed surfaces, continuous operating time and room specifics (ventilation, airflow, finishing materials).
EVSUN EVLN is a hygiene-supporting technology — it does not replace mandatory disinfection procedures in medical, food-processing or other regulated environments.
