Micheal, what do you think is wrong with this broken unit? Here's the situation:
My light schedule for the first half and the second half of the day is composed with symmetrical spectrum and intensity. If I set this broken unit as Master and the other as Slave then the second half light schedule's spectrum won't match with the first.
ex: (same spectrum is set with the same intensity) << edited
10am to 11am - 12640
12pm - 12000
4pm - 12000
5pm to 6pm - 12640
So at 10 to 11am and 5 to 6 pm both have the same spectrum so I expect to get the same color, but I don't get the same color at 5pm. It gives me a totally different color temp at 5pm. However, if I switch this broken unit to Slave and the other to Master then they work just fine. I spent four hrs playing with different color temps to confirm that this broken unit fails to produce identical color temps at different time.
As long as I use it as a slave unit everything works perfectly.
So what do you think is wrong with it? or anything I should know about? Thanks
