Those are the same as the old IceCap reflectors, they do a 24x24 area ok with a hotspot under the bulb. It is also almost the same exact reflector as the ReefOpticsIII.
For a standard 6' 125 gallon tank (72Lx18Dx22T") and a single center brace it gets tough to light adequately. You basically have two 36x18" areas and a reflector that does the 36" will spill way out on the 18". I had two braces on my old 125 which made it easy. I have a suggestion but you may not like it.
