good questions ! the OR2 bar are look the best over full tank with corals so the color from corals reflect back.Are you only using the light bars in this photo? I'm considering your lighting configuration, but its hard to tell if this is the actual representation or are they supplementing another fixture. If not, is there any way to get a shot of just the light bars in action?
I really like the orphek lights but it makes it hard to get a true idea of what the bars only look like.
here is a good example of the OR2 + extra OR1 UV as you can see the UV color reflect on the white send but corals reflect fluorescent color
some client mix the OR2 blue with other light so it blend very well this this photo
some client use Just the OR blue with OR reef day
for example this photo:
or this one ,
