I believe we have the same tank. Mine is the 40 gallon stretch-hex from oceanic in Cherry finish.
I use the JBJ Formosa Deluxe PC
light kit. There are two 65 watt bulbs giving me a total of 3.25 watts per gallon.
Did you get a glass top with your tank? Mine came with a glass top, and the JBJ light just sits right on top of the glass.
There is a picture of it in my gallery.
