In Blender, there are 5 different lights that you can spawn.
The area light will produce a plain of light from the square outline you see in solid mode. The light only shines from one side of the plain.

Area Light

Similar to the sun lamp the hemi lamp will produce a light that has the same light value no matter how far away the source, though unlike the sun lamp, the hemi lamp will produce very sharp shadows.

Hemi Light

The point light will produce light from a single point and the light emits from every direction outward from the point.

Point Light

The spot light will produce a cone of light with a hard edge defining the edge of the cone, and similar to the hemi light the shadows are very sharp.

Spot Light

The sun light will shine light that spreads evenly across the entire scene in the direction of the line that you see in object mode.

I'm not sure why the suzanne head seems to change roughness. I didn't change anything bit the lighting.
