The temp range usually given on here is 95 to 100 the first week, 90 to 95 the second week, and so forth. I found this was too warm for them as they would gather as far from the light as they could get. Since they are outside, I would check on them once or twice during the night to be sure they are not either shivering under the light or piled in a heap in the far corner. And do double secure that light so it can't fall in the bedding!
If there is enough space, you really don't have to be fussy about temps, just so they can get close to or away from it. They will tell you whether they are comfortable.
