A wireframe outline of the light's cone appears. The hotspot region is
outlined in light blue, and the falloff region is outlined in dark gray.

To adjust the hotspot and falloff, do one of the following:
Use the Hotspot and Falloff spinners to increase or decrease the size of the
hotspot and falloff regions. For spotlights, Hotspot and Falloff are expressed
in degrees.
Use manipulators to adjust hotspot and falloff by dragging in a viewport,
as described in the procedure that follows.
By default, falloff value is always constrained to be at least two degrees or two
units greater than the hotspot value. The size of this constraint is a preference
that you can change in the
Rendering panel on page 7768 of the Preferences
dialog. The falloff value can range from 0 to 10,000 units.
When the hotspot and falloff values are close in value, the light casts a
hard-edged beam.
