Quote - I normally don't use points of lights, unless it is a large room scene and the light fills the room.

They are good if you want just a small area illuminated such as simulating
the glow of a candle or a light bulb.  You just need to adjust the Distance Start
and Distance End accordingly.  With a spot light it is too directional and an
infinite light just lights up everything, no control of falloff over distance.
