Yeah those are incandescent wattages. Halides come in 70, 100, 150, 250, and 400 watts, some oddball wattages notwithstanding.
Lots of people mix up halogen lamps and halide lamps, but they are entirely different lighting technologies. Halogen lamps won't work, sorry.
If there was one thing I could get LFS stores to stop saying, it's that a given light will work with [insert name of high-lighting-requirement livestock here]. They frequently will recommend one of their lights because they either don't sell a better, more suitable one, or will recommend a light that is unsuitable because you don't want to spend what the right light costs, and they'd rather make a sale than tell you you can't do it, the livestock be damned. It's a disgusting practice.
I want to clarify your lamps and wattages. There is no PC, VHO, or T5 lamp that I am aware of that comes in 85w sizes. Are you sure it's 85w and T5? I want to make sure we have the right information. I'm assuming it's a standard 75g, so the lamps would be 4' long. If the lamps are 4' T5s, they are probably 54w. Assuming that, there are two things you may consider, besides the lamp changing you are already considering.
First, you can get clip on individual reflectors that clip onto the lamp. They won't be as good as a factory built system, but they should offer a good improvement over what you have.
Second, you may consider replacing all four lamps with the same type. Actinic light isn't very useful for growth, so you are forfeiting 25% of your fixture's capabilities for the sake of that actinic light. Instead, consider a mixed lamp such as the Giesemann AquaBlue lamp, which should look pretty good without any supplemental actinic. Put 4 of those in, and that will help you get a lot more light out of your fixture.
