HPS are in a league of their own, LEDs are OK, but you won't get the same yield.
Icemud, your grow looks impressive. How much did those three LED lights cost and how many watts do they consume? I wanted to go led but could not find any that I could afford at this time. I ended up ordering a 400w hid/hsp light with dimable ballast off of Amazon for $124 delivered.
Those LED's are the Mars II 80x5w version... I have 3 of them. They run about $210 each. Each light consumes about 180w and puts about light equal to a 400w hps. Those are made by Top LED, one of our sponsors here.
Also I am running a new product by Intelligent Gro LED, check out my most current journal. These lights are slightly more expensive, but offer much more intense lighting due to the len's on each diode, plus custom color controlls. These lights also have more of the "key" wavelengths covered with LED chips so they have a slightly better PAR value than the Top LED ones. Also they run almost whisper silent.
