Here's another angle from the end where you can see one of the two fans. I should point out that the whole unit will be suspended from the ceiling with pullies to gain access to the tank. This can be seen in upcoming photos.
Next is a shot of the top of this unit showing the wiring. Closest is the MH ballast, then one of the two VHO ballasts and the empty location for the second one that was still lighting the 65 gallon until I transfered the rock and livestock. Then you see the two power strips which are also mounted to the box. You can also see the 4 eye bolts at the edge of the top from which the unit will be suspended.
