looks_like won't do what you want...

Have you used the orient and circular keywords?
Try something like:
light_source {
<0, 0, 0> // light's position (translated below)
color rgb <1, 1, 1> // light's color
area_light <2,0,0>,<0,2,0>,5,5 orient circular
looks_like{sphere {<1,1,0>, 1} pigment{Red} finish{ambient 1}}
translate <-3, 3, -3>
}

For more realistic results, you will probably need to use radiosity and a sphere
with an emitting media.
Take a look at section 4.1 in the docs (and specifically 4.1.3).
Or try this (rather crappy) scene (note no light source):
#version 3.5;
#include "colors.inc"
global_settings { ambient_light 0 assumed_gamma 1.0}
global_settings {
radiosity {
pretrace_start 0.08
pretrace_end 0.01
count 500
nearest_count 10
error_bound 0.02
recursion_limit 3
low_error_factor 0.2
gray_threshold 0.5
minimum_reuse 0.0015
brightness 10
adc_bailout 0.01
media on
}
}
camera { location <0.0, 5, -15.0> look_at <0.0, 0.0, 0.0>}
plane { y, -1 pigment { color rgb <0.7,0.5,0.3> }}
sphere { 0.0, 1 pigment{Green}}
sphere{
0,1.5
pigment{rgbf 1}
hollow
interior{
media{
emission rgb<1,1/4,1/4>*5
density{wrinkles}
density{spherical}
}
}
translate<-3,3,-3>
}
