Turn full lighting unit into "retrofit kit"?
I recently built a stand for a 30 gallon hexagonal tank and plan on building a hood soon. I purchased a coralife 20" compact quad strip unit for wattage. The light is just a little long for the top of the tank (20" at its widest) and hangs off slightly, but the retrofit kit for the same product was $50 more. I can build a larger hood around the unit, but I think it would look more attactive if the hood didn't have to stick out on the sides so far.
So, the question is: Can I make the full light unit into a "retrofit kit"? The reflector/bulb portion without the encasing looks just like the retrofit pictures on the internet, but I am very concerned about how to enclose the wiring and other parts in a manner similar to the external ballasts on the retrofit kits. This may not be safe or feasible, but I thought I'd ask if anyone has done this before.
