No Lighting displays the surface as though no colored lights were shining on it.

Light Scheme 1 displays the surface with three directional light coordinates: (90.0, -45.0, 0.0, 0.9, 0.0), (-45.0, 45.0, 0.0, 0.0, 0.9), and (45.0, 90.0, 0.9, 0.0, 0.0). To interpret these coordinates, see plot3d/options.

Light Scheme 2 displays the surface with three directional light coordinates: (90.0, 45.0, 0.9, 0.0, 0.0), (45.0, 45.0, 0.0, 0.9, 0.0), and (-45.0, 90.0, 0.0, 0.0, 0.9).

Light Scheme 3 displays the surface with three directional light coordinates: (45.0, 45.0, 0.0, 0.0, 0.9), (45.0, 45.0, 0.0, 0.9, 0.0), and (135.0, 0.0, 0.9, 0.0, 0.0).

Light Scheme 4 displays the surface with one directional light at coordinate: (60.0, 85.0, 0.8, 0.8, 0.8).

User Lighting displays the surface with a user-defined lighting scheme that was defined with the light option in the plot command that created the plot. See plot3d/options.
