I would go with the ai vega. Just installed 8 on a customers tank and they are insane. Im not an led person as everything here at the store is t5 and halides. I know what i get out of the 2 as there is proven history in the 2. I feel with led the market is changing way to fast and no long term data is out there, for instance do you know anyone running the pfo solarace or gen 1 sols still lol lol. They all have switched to the next and newest versions on the market. Just like phones, yes i got the new iphone 5 yesterday and only had the 4s for less than 3 months. But what can be done with the vega as far as controllability is insane.
