Optimal Orientation of MH Bulbs?

[GMGQ]

FYI, despite the interesting swing in the voting, I decided to change the bulbs to front/back aka Perpendicular to the front of the tank. And I lowered them 6 inches:



The tank is definitely brighter, and I think the lighting is more even now. We'll see how my corals like it.

Your pfo optimal perpendicular reflectors are meant to be mounted perpendicular, so that is how they should go, I assumed you would have changed them after learning that.

Yes, that's why I changed it despite the swing in votes.

But I have seen a lot of people mount them Parallel too. Heck that's why I originally had them parallel.

Definately. I would have done the same if I bought your reflectors, because I currently use their 36" reflectors, which obviously go parallel, so I would have done the same.

So I guess everyone should double check with the manufacturer of their spider-type reflectors to make sure they are using them in the correct orientation.

Have you got a pic of your lighting and tank so I can see?

[GMGQ]

Well here's a pic without any adjustments on the camera:



I usually tone down the expostion to -1 or -2 for better contrast though.
