WTB led light for 7.5 cube

[Fifty]

I'm upgrade my 1.5 gallon spec to a 7.5 gallon cube. The light I have now is a 8 watt led that I got from marinedepot.com, moolight included for $100.00. I have a Zoa frag, green torch and Xenia frag for the last 6 months. Everything is doing great but now with the update want to get more frags and not sure what light I should get. Any suggestions would be appreciated ! Thank you
