On my 120 I'm running two 400 watt MH's with Hamilton 14ks. Also two 48 inch Actinic VHO's. This works well, but the upper parts of the reef get so blasted with light that no corraline will grow there.
If i were to do it again, I'd go with two 250 double ended HQI's. They put out more light than you would think for a 250, and save quite a bit on electricity and heat generated.
I'm also considering doing T5 on my new 210, but at 7 feet long, I'm not sure how that will work out, so I'll likely stick with MH.
Go with a couple of 250 HQI's and actinic VHO or T5s
