Photometric Test Laboratory

The quality of PROLED products is subject to strict quality control parameters. To guarantee the highest possible quality assurance, the LED products are regularly checked and rated by our in-house photometric test laboratory. Our optical test equipment is from Instrument Systems, the worldwide market and technology leader in LED measurement. The photometric laboratory of MBN allows the measurement of wavelength, colour temperature, colour spectra, colour reproduction index (CRI), radiant power, luminous flux among others and consists of:

    • Spectrometer from Instrument Systems
    • Integrating sphere 100 cm from Instrument Systems
    • Goniospectrometer from Instrument Systems
    • Spectra software from Instrument Systems
    • Various calibrated filters, apertures, supports etc. from Instrument Systems
    • Thermal imaging camera and heat chamber

    The values measured in our laboratory are the actual values of the complete end products. Therefore they aren‘t just calculated (theoretical) values based on the data of the chip manufacturers. The values of the chip manufacturers were measured under ideal laboratory conditions and refer just to the chip (without optics, reflectors and case) and not to the complete end product, so these values do not correspond with reality in practise.

    We have decided to provide the actual photometric data to our customers and not any theroretical and promotionally effective values as many other LED lighting manufacturers.

    For all LED products measurement reports are available. It is to consider, that the tested values are momentary readouts of the respective test product. The manufacturing of LED chips is however subject to certain tolerances (due to conditions of production, different production batches), so minor variations among the same products can occur. We have to point out herewith, that our measuerd values do not guarantee certain product properties.

    PROLED products shall meet their projected requirements at the intended operating location in an optimal way. Hereby it is inevitable to determine the spatial light distribution in terms of radiation characteristic of each individual product.

    The MBN in-house measurement laboratory receives a gonio spectral radiometer from Instrument Systems for this purpose, the brand and technology leader in LED measurement technology.

    The LGS gonio spectral radiometer from Instrument Systems was developed specially for the determination of angular dependent radiation characteristic of LED modules and lamps. It is suitable for objects up to a size of 1900 mm and provides a highly precise measurement grid due to the extremely fine angular resolution of 0,01°.

    Thus we provide lighting planners and architects extremely precise radiation characteristics of our products in form of EULUMDAT and IES files, which can be created by yourself via the free and stand-alone PROLED DIALux Plug-in* or obtained directly from us.

    *PROLED DIALux Plug-in
    The PROLED DIALux Plug-in is a free and stand-alone app. It contains all PROLED luminaires and a FLEX STRIP–PROFILE configurator. Directly from the app you can transfer the selected luminaires or the configured luminaires to DIALux or export these to other data files (EULUMDAT, IES, ...). The PROLED DIALux Plug-in can be downloaded HERE.

    The PROLED DIALux Plug-in is also available as a Online-WEB version:
