JavaFx Lighting Effects : When to Use which ???

Question

Hi,
I know that this question in more design oriented than technical,
but still i'm posting this question in this forum .
I wanted to start off with javaFx lighting effects and i have found very good examples online .
I have seen the implementation of lighting effects at:
[http://code-better.com/javafx/lighting|http://code-better.com/javafx/lighting]
and [http://jfxstudio.wordpress.com/2009/03/18/javafx-light-effect/|http://jfxstudio.wordpress.com/2009/03/18/javafx-light-effect/]
These applications just gave us the ability to configure the lighting options .
I also have found a file effects.fx online and in that i see that
effect: Lighting{
light: DistantLight{azimuth: 90}
} // to be used to make a button look pressed
and
effect: Lighting{
light: DistantLight{azimuth: 270}
} // to be used to make a button look upbeat .
But this hasn't worked for me in few scenarios .
For example i have tried to apply these 90 and 270 distant light effects
to buttons made of various gradients and for some it seemed to have worked and
for some it doesn't seem to have worked .
I think we will have to change the color of distant light for that .
Could any one point me to a guide or online site or some tips
that will help be in understanding which effect to use when and which color
should i use for the lighting effect and other stuff .
It would be of great help for me .
Thanks a lot .
bye

Hi JavaFx Duo,
Thanks for your reply .
Actually I wanted to find out info like how to make an image ( or button of any gradient )
look gone inside or look up ( in a measurable way, i mean depth or height below/over the surface )
using lighting effects . And how does the azimuthal angle
and the color of the light source have an effect on it .
Earlier i have posted a forum in which Phi Lho has answered me
on how to make the button text look gone down and i can try to achieve
that by trying similar here .

But i thought of making use of the lighting effects and i want to know if any guide or tutorial
is available which describes the lighting effect with various Colors
and angles and when to use distant light/point light and spot light effects .
I would also like to know a few practical implementations
of these effects in javaFx ( i.e as i have posted earlier 90-for making it look deep and 270 for looking elevated
and such stuff ............................. ) by varying the angle and Color ,
So that i can use them in my applications rather than trying various combination
each time .
Thanks
