What you see in the photos is not true colour. Me and the camera are having some arguments with trying to take pictures of the deep blue. In person those are a stunning deep blue. For the 6 lights on the blue dimmer per circle I have 3x450, 2x440, 1x420. In person only the 420 looks purpleish.
I feel the Nova a8 works great with the center brace on my tank. I dont notice any shadowing from the brace as I have it lined up so theres 4 circles on each side of the brace. I'm impatient and really cant be bothered to deal with 2 lights and Im loving the Nova. Super happy I went with it.
