Hi,
I am sorry it was a little difficult to tell how it was set up...but it looks as if the UVB is on TOP of the screen...which will *not* do beardie much good...it needs to be IN the tank w/o anything blocking it...even take the plastic cover off of it so that it is just bare bulb.
So...the UVB *inside* the tank, not ON the top screen.
NO plastic cover over the bulb...just bare bulb.
Clear as mud?LOL
It is great that you are getting all the info for your little beardie!
