Humm. I don't know. I would guess from the description that
the lights are probably too close to the surface, if they
only illuminate small fractions of the surface. Have you
tried backing them off a bit?

Ambient light is NOT what you want, I think, since this
will light everything up uniformly. You want light that
will show the edges of things.

Cheers,
