I had same issue, all the plugs and wire management was a pain for me to deal with over long-term use. Thats why I'm making the switch to meridians.Dang a 63 would be nice over my new 84x30x25 tank since I'm not lighting the ends. Too bad I already built a t slot mount for my 6 noopsyche. But six power bricks and six cords is a hassle. Any info on the mounts that will be available? I have a couple photon v2 and the tank mounts and bot mount work but the bot always tips forward a bit and isn't great looking.
My rock work/coral placement is only 60" wide and in middle of tank. So, the two 63" units will work perfect cause I won't light the ends either. If I really need more light I could always get a 24" or 36" and add to the 63's to have seemless coverage.
Im not sure about mounts it will come with but it should be an easy fix to mount them over your tank. I think over your tank it will look great and you could add the edge bars for wider coverage down the road.
