Photometric, colorimetric and photobiological safety testing laboratory
Our aim is to provide an in-depth understanding of emitted light and its colour attributes of any type of luminaire, ensuring the highest accuracy of measurements. The obtained results - either printed or digital - can be used in making a description of the luminaire and in lighting design with popular programs, e.g., DiaLux, because the data is printed and digital format. The results may be also used for research purposes.
Luminaires and light colour measurement laboratory was established in 2014. Photometric and colourimetric tests are carried out with higher precision equipment produced by Lichtmesstechnik Berlin (LMT Berlin). The laboratory is made in a way to minimize reections from surrounding walls, ceiling, floor. The test room is maintained at a constant environmental conditions (25 C+/- 1 C).
Double monochromator - photobiological safety testing (ražotājs: Bentham Instruments Ltd.).
Corrosion resistance of metals - chamber for neutral salt spray testing for the provided test object.
Newest addition IPXX - devices for IPXX (IP1X-4X and IPX5-X7) testing and coming soon - other IP and IK (Ingress (foreign objects, water) protection and impact protection) testing.
Luminaire luminous flux (lumen) measurements
It is possible to measure lamps and luminaires up to 1.8 m diameter, 50 kg weight and with power up to 1500 W. Also available to measure with near field configuration E27 light sources up to 1,2 m diameter. Measurement range: 0,0001 lx – 80000 lx.
Including - incandescent, halogen, discharge, fluorescent (tubular and compact) light bulbs and lamps, also seperate LED and LED modules (provided with DC driver). Individual cases require specific connection and mounting to the goniometer.
- Thorough measurements with high accuracy ftotal ≤3% (acc. to EN 13032-1, Table 3, footnote c), using LMT Mosaic Filtering® photometric system with V(λ) match f1≤1%
- Each luminaire undergoes appropriate thermal and electrical stability cycle
Receiving the results:
- Test report includes detailed photometric, colorimetric, electrical, photobiological safety results (depends on the measurement) in .pdf and/or printed version
- Digital results are available in Eulumdat .ldt, IES file .ies for ease of use in light planning programs
