In my 180 Hap/Peacock I run 2 36" Current Nova Extreme's T5. I am running the daylight bulb that comes with it and adding a NON HO actinic bulb. (In each unit - 2 bulbs) I tried it with a HO actinic bulb and it was too blue. NON HO actinic bulb was just enough blue to really bring the colors out but not look too much like a salt water tank.
I agree with rgr4475, I've tried CF, VHO, T5s, I've had the best experience's with T5, you can get two 36" for even coverage, though make sure they will fit properly.
They are bright, cheaper than CF and the bulbs last two years.
I would personally not go any other way. For a fresh water tank, the reflectors are not too critical, so a "standard" kit will be fine. If you were going marine then it would be more important to invest in a lamp with individual reflectors for each bulb.
i got a 120g 48" tank and also have the nova light fixture (use to be for saltwater fish). It uses 4 t5 but now with the cichlid tank i just use two bulbs. i use one aquasun 10000k and mix it with a acintic. I personally like the bulb color combo especially with a solid black background
