Lighting for a 80" long Tank

[HOBrien]

The tank measures 80"x24"x24". It will be FOWLR. I currently have a 48" T5 4bulb fixture I can use for this tank but not sure what the best thing would be to do. I will not get MH and single reflector is fine for what I am having in the tank. So basically I need fixture lenght configurations as I know where I will get my lights.

I was thinking of getting a 36" fixture with the same bulb set up to cover the rest of the tank.

Would this work or not look good?

84" ?? Would it fit? If it does, yes it will work. But why not just use a 2 lamp vho set up? You idea will of course work. I used 2 36" units on my 72" tank.

The tank is actually 80" it was a custom build about 8 years ago. The lights with what I was thinking of doing will overlap for a few inches but I think it will be ok. What lengths of VHO are you saying to use? I can get the 36" fixture for $69. Would there be a difference in the visual light between the two fixtures being one is 54watts per bulb and 1 is 39watts per bulb.
