Will this be enough light?

[ensquire]

I am almost ready to put my 80 gallon tank back online after a total overhaul. Taking forever.
The tank is a bowfront with a LR overflow 40" x 20"D x 22"H
The aquascape will be mostly on the right side where the overflow isn't, and I am going to try a mixed reef. At this time I have a few fixtures and was hoping that they will do the job, but am unsure and have been looking at other options. But for now can I get started with SPS , LPS with a 36" 6 bulb T5 fixture ?
I also have 2 36" PC fixtures that came with the tank but not really liking the way they were set up and does anyone use PC anymore?
Have looked at some of the new LED fixtures , but waiting for a bit longer before jumping in.
Opinions , suggestions welcomed .
Thanks
