Are you looking for help with the wiring of the ballasts to the endcaps and bulbs, or are you looking for help with a canopy for the tank? Also, how are you getting 410w out of four bulbs. The highest wattage bulb I've seen is the 36" 96W bulbs. If you haven't ordered your ballasts yet, I would recommend checking out
www.ahsupply.com They have kits which include everything you need to put PC lights in a canopy. They also have prebuilt canopies as well as free directions to make your own.
I have 220w (4x55w) over my 40 gallon breeder tank (36x18x17). I have the bulbs staggared so there aren't any spots where the tank isn't covered by the lighting. If you have any questions, email me.
