Is This Lighting Enough? Help!

[Cole's Coral Shack]

I have a 120g, 48x24x24, and I am trying to figure out whether or not the lighting I might go with is enough. I am planning on using 1 48' 4 bulb T5 and 2 48' TrueLumen Pro LED Striplights. I am mostly looking for the LED Striplights to enhance the color of my corals, but truly expecting the growth to come from the T5's. Is 1 48' 4 bulb T5 enough light to get good growth? I am looking to mostly grow softies/LPS.

I had a 90g and used a 6 bulb T5 setup. SPS was on the top 50% of the tank. Growth was very good.
Whatever direction you go, I highly recommend individual reflectors for T5.
