Scale & Lights

When I make a "scale" on a 3D shape (ex a sphere) happen that light on it change drastically... Exactly when I "enlarge" it, the sphere become darker while, when I "reduce" it, the sphere become very bright... Where is my error ? What can I do ?

[CS]

Use ...
glEnable(GL_NORMALIZE);

[CS]

[Dodger]

or glEnable(GL_RESCALE_NORMALS) if available. Might be slightly faster then GL_NORMALIZE, depending on the OpenGL-implementation.

Thanks a lot!!!
