Hello,
for a cone angle of 70° you need a spread of 35° if you want it to start
from the center. This should work unless the intensity is greater than
1, or you might have other lights burning the "white point" of the spot.

This seems basic but it has always confounded me. I would like a
softer fade from the center of my spot light to the outside of the
cone angle. Adjusting the spread seems to make little difference. See
the linked photo for an illustration. I don't understand why the
falloff does not start at the inner ring of the cone and fade to the
outer edge? There seems to be a limit to the amount of softness I can
get out of a light. What am I doing wrong?
