Light distribution curve

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.


For products with this note you can create by yourself EULUMDAT and IES files via the free and stand-alone PROLED DIALux Plug-in* or obtain these directly from us, to import them into your light planning software (e.g. DIALUX or RELUX).


Furthermore MBN-PROLED is DIALux premium partner and RELUX member. Both, DIALux and RELUX, are cutting-edge light planning softwares for calculating and visualization of indoor and outdoor lighting installations. The PROLED partnership with DIALux and RELUX allows lighting designers and architects to integrate PROLED luminaires directly in projects without any effort.


*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.
