I'm looking for a light that its power will be reduced by distance
(squared distance)
light_source {} seems to just spread out and not lose its power.
Also, atmosphere, halogen, and many other features don't work at 3.1g.

I have several neon-lights - 4 red, green, and blue.
when I place a light-source on them (I can also use looks_like) on the
appropriate color,
everything gets colored in white, except for tiny areas which are on
shaded.

How about fade_power and fade_distance?

See chapter 6.5.7.9 in the 3.5 docs.

I have an old Pov-Ray version - 3.1g.
it doesn't support atmosphere, halogen, and several light settings.
I'm getting a new version.

Hey, it is not old, it's the current one, while 3.5 is still beta.
Atmosphere, and halo (if this is what you mean) were replaced in your
version (and will be in all following ones) by media, which is much more
flexible.

fade_power and fade_distance are supported by 3.1g and you really should
check the docs about those features.

  And what the heck does fade_distance and fade_power have to do with those
things?
