Hi there,
Nice work. 
I see those pics, Looks like you have it installed correctly.
I’m curious two things , Is the Light on always? have you measured the heat it generates?
I know your probably LOL at that but , I’m hmmm… Something is generating waves.
turn it 90 degrees and also test that.
These things are almost an Art form in getting to work reliably and repeatable. Takes some fiddling and work. by no means plug and play IMO.
Your on the hunt so you’ll get it…
A) power supply
B) Temperatures ambient (try lowering the temp)
C) Orientation
D) TEST
is the check list.
