How to achieve brighter shininess using GL_LIGHT1? - c++

Question

I have this image
Is there a way to achieve brighter look of the light without editing specular material part of the code?
This is my current code:
void drawTeapot() {
GLfloat mat_diffuse[] = {0.2, 1.0, 0.8, 1.0};
GLfloat mat_specular[] = {1.0, 1.0, 1.0, 1.0};
GLfloat mat_shininess[] = {128.0};
GLfloat lmodel_ambient[] = {0.1, 0.1, 0.1, 1.0};
GLfloat light_position[] = {1.1, 1.1, 1.0, 1.0};
GLfloat light_specular[] = {1.0, 1.0, 1.0, 1.0};
glLightfv(GL_LIGHT1, GL_POSITION, light_position);
glLightfv(GL_LIGHT1, GL_SPECULAR, mat_specular);
glLightfv(GL_LIGHT1, GL_SHININESS, mat_shininess);
glLightModelfv(GL_LIGHT_MODEL_AMBIENT, lmodel_ambient);
glMaterialfv(GL_FRONT, GL_DIFFUSE, mat_diffuse);
glMaterialfv(GL_FRONT, GL_SPECULAR, mat_specular);
glMaterialfv(GL_FRONT, GL_SHININESS, mat_shininess);
glutSolidTeapot(0.5);
}
I have to use GL_LIGHT1 because there is another function that reacts to mouse clicks and turns that light on and off. Therefore, I can't have the specular on the object before the light turns on. It has to remain matte, sort of. As you can see, shininess is on max, specular also, but it's not really what I'm going for. I basically want it to be tiny bit bigger that it is now, more dispersed.
