Tests of assemblies and elements for internal and external lighting and road lighting

Photometric measurements are performed in an air-conditioned photometric darkroom equipped with a photometric tunnel 25 m length. Our photometric laboratory offers a wide range of accreditation and extensive experience of our research staff. Test reports and photometric files are prepared individually for the tested luminaires.
The indications of our test equipment are monitored continuously using standards registered by the Central Office of Measures to ensure fully reliable research results.

In addition, except research in the field of lighting technology, the laboratory offers a wide range of research aimed at developing and controlling the quality of lighting products.

Our offer includes advanced vibration tests, which are crucial for assessing the strength and durability of lamps and lighting poles.
Our tests include vibrations that accurately reflect the conditions in which the products will be used.
The photometric laboratory has extensive capabilities in the field of lighting technology, which enables the assessment of the impact of environmental conditions on the functional parameters of fixtures, such as electrical, colorimetric and photometric parameters, which can be checked immediately before and after vibration tests.
A wide range of accreditations in the field of lighting technology guarantees the certainty of the obtained measurement results.
Thanks to our experience and the use of the latest technologies in the field of vibration engineering, we are able to conduct an in-depth strength analysis, identifying potential structural weaknesses and suggesting appropriate improvements.

• Temperature cycles in climatic chambers
• Measurements of luminous flux changes as a function of temperature
• Aging of LED modules and luminaires (i.e. by UV radiation)
• Tests with different parameters: temperature, humidity, contamination
• Temperature shocks, splash tests
