reference guide, the maximum tilt able angle should be considered while
deciding the number of lumens sent above the horizontal plane i.e. 90 degree
from nadir. Will there be any concession in this project where, of course,
lamps are throwing lumens up side but most of them being reflected back to
ground by façade and hence, are not causing any night sky light pollution.<o:p></o:p></span></font></p>
