Kevin,
Your pretty tight width wise on your light fixture, I think you’d have hard time getting in an 85 watt CFL bulb into that fixture. It would hurt to try. On my fixture I used this adapter http://www.1000bulbs.com/product/5840/ELEC-242515.html I had a lot of room inside the fixture, I believe this is the same adapter that 2biz used also. You could replace the socket with something like this http://www.1000bulbs.com/product/3812/SOCK-L70045.html or this http://www.1000bulbs.com/product/3813/SOCK-243201.html
I think I’d do one bay, gut the fixtures and change out the socket. Are those 175watt MH fixtures? They like look pretty small, more like a 100 watt fixture.
