Lighting Question!!!

[HaZRaTTy]

Hey looking around @ Lights and different combinations. I have checked eBay.

I found a few that were dirt cheap, what do I look for outage on these lights compared to Tek and other name brand T5HO systems?

This is the fixture I stumbled across.

There is also this one for double the price.

What lighting setup would you guys recommend? I've done so much research and I've been in the fish world of quite some time, I just can't grasp the Lighting aspect and how much I will need.
