i did think that i have it at about 2¾ foot at the moment and the temp is at 26/27°c how hot is safe??
with a 400w i would say 2 foot is a good distance for the young plants. and you temps are fine in that 26-27 area if your can put your hand under the lampe at a XX distance for some minutes and it feels like a nice temp for your hand, then the plants should be fine. If your hand think its to hot the plant top most likely will find it to hot as well
