Led help for 75 gallon and apex controller

I will be switching from my 6 bulb ati t5 to LEDs. I don't know where to turn with so many out there. I also want them to hook up to my apex. I do have the center brace in my tank and cost wise I would like to stay under 800. I know there is a lot of info out there but just seeing if anyone has LEDs with apex on a 75? And If anyone is interested in my fixture let me know. Also it's a mixed reef and would prefer to hang rather that mount in a canopy
