48 inch light over 60 or 72 inch tank

I was wondering if anyone here has seen an aquarium with a 48 inch light over a 5ft or 6ft tank. I am trying to have a gradient so that I can keep a wider variety of corals, as my current setup (6x54 watts) is too much output for my current creatures (soft corals and a clam). My light is 8 inches over the tank and I still need to keep a glass canopy over the tank to keep the light down far enough so that the polyps are more "happy" looking. I'd like to upgrade from a 4 foot tank to a 5 or 6 foot tank, but am unsure how that would look. The amount of "spread" I am getting at 8 inches above the tank seems sufficient from across the room, but things change when you actually make the setup.

I have an ATI Sunpower 6x54, and it's much more powerful than I could have imagined. I like the idea of keeping the fixture because of low heat output and adjusting the look with 6 bulbs.

I know that a 4 foot fixture over a 6 foot tank is a stretch, but they are much easier to find than 5 foot tanks. I was just hoping that someone around has tried this or seen it tried. I understand that the sides won't have bright lighting, and I think that using this as "low light" coral space and extra swimming space can work well with a mixed setup.


Thanks,

I have a 5ft light over a 6ft tank and it works great.

4ft over a 5ft tank would work great, over a 6ft would probably not be enough on the ends.
 
5 foot tank is ok, 6 foot youll have too much dead area on each side, a foot on each. 5' is ok with 6" on each side.
 
I have a 4 ft light on a 6 ft tank and it def. Does not spread the light to the ends. Some very low light Corals would be fine but other than that it won't work

Do you have any pictures? I'm just curious about how low it gets on the sides. Also, how high off of your tank is the light?
