Yes i will do that, it looks really sterile, but i wanted to test now so i could return the fixture if it didnt wrk out, The 85* section is like the upper left 3x3" corner then drops immediately 82*-----I'll work on a diagram, maybe i could try a sunglo that is less than 40w, but i think the whole tank will drop to a highest of 76* everywhere like it does when just the right side repti 26w uvb floure is on---no gradient at all
