Hello everyone
I installed Dialux 4.13 and I made my first lighting street's calculation. I have two questions:
_why the maintenance factor is 0.67? which level do I insert with led's source?
_What is the drop dopwn menu (A1, A2, A3, etc.) under the inscription CIE 140/EN 13201?
Thank everyone who help me

Dear roberto.galimberti,

According to the CIE 154 a reference value for the maintenance factor of 0.67 should be specified. This value corresponds to the maintenance factor at low pollution. But you can change the maintenance factor for the street to your needs.
The dropdown list under the standard CIE 140/ EN 13201 stands for the illuminance sitution which can be selected there.

Best regards,
