I don't know about your stand but if it was sent by AGA then it should be fine. My stand is wood and holds a 90 gallon tank thats 160 pound of glass, near 1000 when filled with water, and I have over 100 pounds of live rock. Hard to believe but it does hold.
My preference is VHO lighting, that should do fine with a fowler. You can either look up a 2 bulb set or a 4 bulb set. Trick is that a 48 inch light bulb doesn't usually fit into a standard 48 inch canopy. The bulb with endcaps winds up 49.5 inches long, so if your building watch for that.
My canopy is 48 inches like yours but I use 46.5 inch bulbs that are 110 watts per bulb, 4 bulbs, + Metal halides.
Some folks like PC bulbs and all the fancy stuff that goes with them like moon lights.
Up to you
