That doesn't really give me the effect I'm looking for...

See here:
1)

This is more or less what i want.. see the light on the porch.. The problem is that there is no decay here.. so the light hits the ground which I don't want to.. I want it to gradually disappear


2)

Here is Quadratic Decay, light intensity 1... it sucks.. very weak light

3)

Here is Quad D, light int. 10.. still sucks.. the light it way to strong at its origin and it dies off way to fast, doesn't even illuminate the porch

I read somewhere that you can adjust decay (or light drop off) for spot light using graph editor and then change that light to point light and the decay settings will stay.. but no instructions on how to do it.
