Photometric Testing Laboratory
We verify your lighting performance parameters and show how your products behave in real-world conditions. Using high-precision instruments, we measure all relevant photometric values. Our laboratory is continuously updated with the latest technological advances, and our quality management system guarantees a high level of accuracy and reproducibility in every test.
We use a Far Field Type C goniometer to analyze light characteristics, and to ensure accurate results that comply with LVS EN 13032-4+A1:2019 standard.
Our scope of accreditation includes:
- Luminous flux
- Efficacy
- Correlated Color Temperature (CCT)
- Color Rendering Index (CRI)
- x, y chromaticity
Accreditation
Our lighting laboratory has already implemented a quality management according to LATAK accreditation T-696-00-2025. We use a Far Field Type C goniometer to analyze light characteristics, and to ensure accurate results that comply with LVS EN 13032-4+A1:2019 standard.
We create custom test reports based on individual client needs.
