Il put them to 10 inch and see how they do then work my way down

So if the temp where my plants are gets up to 95 is it ok if, i have air temp that is 70-75 blowing on it, and everywhere else in the room except under the lights.
I have a 600 and a 1000w hps, and have grown for a number of years, and I don't think I could not tell you what my temps are because that's not the way to measure it. I have the 1000W generally around 12" from the top, but occasionally down to about 9". In fact I have a piece of twine hanging from my lamps with a small weight on the end of it. Then I have a knot in the twine at 12", so I don't have to estimate what a foot is, and I can just look at the twine and see if the lamps need adjusting. Just hold the back of your hand up and just near the top of your plants under your light. If its comfortable for the back of your hand, it will be alright with the girls. Are you growing soil or Hydro? ...because it makes a difference of the the nutrient tanks or reservoir -- you really don't want them to get into the 80F+ range, best around 68 or 70F.
