Sun: Simulate a distant light source that behaves like the Sun.

Spot: A point that cast light in a cone shape.

Area: A squared shape that emits lights from all the available

shapes.

Each one of those lights has a purpose in a project. For instance, in a

scene that tries to simulate daylight, you will probably use a Sun

combined with an HDR map for a Cycles render.

It is possible to add each new lights using the SHIFT+A key or change

an existing light source type by selecting it and opening the Object Data

tab. There you will see buttons at the top where you can quickly swap

between each type of light (Figure 6.22).
