Tek, Coralife or Hagen T5's?

I just got a new 85G tank which has T5's currently in a do it yourself setup with 6 T5 ballasts 48" which I want to change as it dosent look to safe. Its DIY wiring etc etc.

I hear so many different opinions, so which is the best? I would rather not spend a fortune but it looks like they are all about the same in price?

I need a 48" length what should I get?

Thanks in advance!:icon_smil
