Check out app.cpp
Code:
        // Add light source
        H3DNode light = h3dAddLightNode( H3DRootNode, "Light1", lightMatRes, "LIGHTING", "SHADOWMAP" );
        h3dSetNodeTransform( light, 0, 20, 50, -30, 0, 0, 1, 1, 1 );
        h3dSetNodeParamF( light, H3DLight::RadiusF, 0, 200 );
        h3dSetNodeParamF( light, H3DLight::FovF, 0, 90 );
        h3dSetNodeParamI( light, H3DLight::ShadowMapCountI, 3 );
        h3dSetNodeParamF( light, H3DLight::ShadowSplitLambdaF, 0, 0.9f );
        h3dSetNodeParamF( light, H3DLight::ShadowMapBiasF, 0, 0.001f );
        h3dSetNodeParamF( light, H3DLight::ColorF3, 0, 0.9f );
        h3dSetNodeParamF( light, H3DLight::ColorF3, 1, 0.7f );
        h3dSetNodeParamF( light, H3DLight::ColorF3, 2, 0.75f );


The bottom three commands set the color (which is slighty dimmed and red). Also depending on what else you changed, try modifying "RadiusF" to set the size of the lightsource or its position/FoV entirely.

Not sure if you're talking about fixed function OpenGL lighting,... that won't work because Horde3D does not use fixed function opengl methods.

How can i change the way horde3d animate object, for example
how can i add some cuboids or cylinders to the scene?
horde3d is based on glfw, i thought i can add some object just like it was in glfw, but just as you said it did not work, so
i was really confused about that?
can you help me Plz.

Thanks a lot.
good luck.

Horde is not based on GLFW, GLFW is used to create windows and grab signals from keyboard and mouse. Horde generates image that is later displayed by GLFW.
You can learn more about animation in horde via documentation. There is plenty of information how animation system works.
Horde doesn't have functionality for adding primitives. If you wish to display models in horde, you'll have to import them from modelling tools like 3dsMax via ColladaConverter.
