I have a catalina 4 x 54 T5HO over my 75 gallon. I have 2 bulbs on for the entire lighting period and the other 2 only on for a 2 hour "mid-day" period. The catalina has two switches to allow this type of setup. I have been very happy with my catalina light and recently bought another one. I have plenty of light and my plant growth has been great.

I was also worried that 4 bulbs was too much. It probably is for my setup, but I have the flexibility to grow anything I want. With the catalina, it is such a good deal (compared to tek) that I went ahead with the 4 bulb fixture and I don't regret it.
