I'm running 2 120W ebay fixtures on my frag tank and everything seems to be doing well.  I'm definetly getting better results in my display though.  If I was setting up a nano I'd not hesitate to run these.  For you tank, I don't think I would. 
 
I'm making the switch to LED on the display and I though about the radions, but went with the AI Sols.  Cheaper, and apparenlty better PAR.  $1600 for 2 radions... $800 for 2 Sols.  Tried and tested.
