Your light demo looks nice.
The other objects just have too few faces.
As the light reflection is pixel-by-pixel Gouraud
interpolated using the light values at vertices, few
faces means poor light effect. A simple example is the
look of a sphere with few faces against a sphere with
large amount of faces. The low polygon count sphere
will reflect the light in a few special angles, but
the high polygon count will looks nice all the time.
Solution:
Build, or import, a cube with more mesh faces per
side.
Tip: if you put a 4 side base Cone build as :
Cone top = new Cone(sideSize, // x size
0.01f, // height,
primflags, // primitive flags
4, // 4 side base
32, // 32 division border to
centre
a ap); //the appereance
just over you cube or ground object will solve it by
increasing polygon count of the enlighten surface.

PS.: my eyes are failing or that cylinder light really
dimmer up and down ?? This effect with light color
changing from orange to ligh blue should be
terrific...
