LEDIL IES & EULUMDAT files


Please keep in mind that the files we provide are not 100% accurate.
We measure the lenses with 250mA current using symmetry when possible.
If the data you need is not available, please make a request.

VERY IMPORTANT TO NOTE!
True Light Output Ratio (LOR) is NOT the one you see when opening the file e.g. Dialux.
We measure LOR in an Integrating Sphere, because only that way you can calculate correct efficiency for a lens or a reflector.
You can find the true LOR value from our website.
