Just to be clear, it wasn't the WS light hub that caused my ITAD to smoke itself. Rather, it was my own inattention to details, i.e., leaving an exposed wire connection under the layout. That was for some other things I was doing and neglected to clean up.
So far, I do like the WS light hub. No doubt less expensive ways to light up buildings but using Hobby Lobby coupons helps make the components reasonable.
