Hello,
in LZ3, no more than 5% of the total initial designed fixture lumens should be emitted at an angle of 90 degrees or higher from nadir (straight down). Do you think we can propose meeting this requirement by turning off part or all of the external lighting during night (eg. from 11pm to 5 am, same as for interior lighting), while not necessarily having cut-off luminaires. Any idea this could work?
Thank you
