They last few times I was in Jerusalem I've noticed just how few LEDs are in use there.

 

Anyone have any measurements / experience on the effectiveness of Broadband Light pollution filters for?

 

In the negev we're LED only now, and half of them white. I'd given up even thinking of getting a nebula filter.
