I would agree that the Current USA bulb is one of the better ones out there. If you buy inexpensive bulbs, they will likely require more frequent replacement and not put out the colors that you want.
If your keeping a reef tank, I would do a little figuring first.
Four 65w bulbs at about $30ea is roughly $120.
PC bulbs should be changed every 6 months to maintain their output. If you are going to keep corals, light output is a major concern.
So compare roughly $240 a year to use that PC fixture verse buying a good T5HO fixture with an expected bulb life of closer to 18 months and a bulb cost of around $20.
It quickly becomes apparent that T5HO will save you money in the long run as well as provide much better light output for longer durations.
