Notes:
•
•
Intensity (I) and illuminance (E) data are normalized by 1000 lm
The optical values shown are the result of optical simulations carried out with ASAP and
ZEMAX software systems. The optical simulations are carried out on the basis of the typical
values provided in the LED manufacturers’ official datasheets. The photometric analysis has
been carried out on physical samples. On request, by supplying your PCB, we can provide
the measurement photometric file.
