Add a Light
At the moment there are two ways to add a light source in the editor:
Area light
HDRI light
You can add an area light by clicking on the Camera & Lights button and then clicking on Lights and then Area Light.
Which will add a rectangle like object in the middle:
Targeted vs Non-Targeted
If you click on the target you can also adjust where the target of the light is. The light by default will move around a fixed point in space:
If you change the Targeted toggle:
you will have a Non-Targeted Light that is not fixated on any point in space.
Width and Height
You can change the width and height of the light:
Intentisty and Color
furthermore you can also adjust the intensity and the color of the light. If you change the intensity it is good to keep in mind that the intensity of the light will depend on which type of light you chose.
You can choose between the two types of Area Light:
Blender: The luminous flux (the intensity of the whole light) remains constant, meaning that increasing the surface area (width and height) will not affect the overall intensity.
Corona: The luminance of the light (the intensity in a given unit area) is constant so if you increase the size of the light it will increase the intensity of the whole light as well
To change the color of the light, you simply have to pick a color from the color picker.
Visibility
In some cases it is important to adjust whether the light is visible to the camera or various reflections, and this you can change in the visiblity settings:
