I would use those patches in povray that are translucent, like the
bicubic patch.
Here's a example code. Have a look at the texture statement. It's only
rgb ... not rgbt.
camera {location <0,5,0>
look_at 0}
light_source {y*0.5 rgb 4}
bicubic_patch{
type 0
flatness 0.001
u_steps 4
v_steps 4
<0,0,0>,<1,1,0>,<2,1,0>,<3,0,0>,
<0,1,1>,<1,1,1>,<2,1,1>,<3,1,1>,
<0,1,2>,<1,1,2>,<2,1,2>,<3,1,2>,
<0,0,3>,<1,1,3>,<2,1,3>,<3,0,3>
texture{pigment{rgb<1.0,1.0,0.8>}
finish {ambient 0
diffuse 0.4
reflection 0}
}
translate <-1.5,0,-1.5>
}
Hope this one helps.

You could try adding no_shadow to the shade, then give the shade some amient
value to make it look like it's glowing from the inside, but that won't make a
defined shadow against the wall, so make a slightly smaller version that is grey
with high transmit value (but not 1) to create the shadow effect.
Just a guess at a workaround
