Visible directly – When enabled, this makes the Corona Light directly visible to the camera.

Visible in reflections – When enabled, this makes the Corona Light directly visible in reflections.

Visible in refractions – When enabled, this makes the Corona Light directly visible in refractions.

Visible to alpha channel – When enabled, then the light is displayed as opaque (white) in the alpha channel.

Visible in masks – When disabled, the material isn't visible in any masking pass (ID, mask, source color,etc.).

Generates caustics – Enabling this option allows for generating caustics.

Material ID – This parameter defines the ID used for this material.

In this example, the Corona Light Material is applied to the mesh behind the mirror, the ceiling spotlights, and the strip light in the top-right corner of the room.
They all have the Emit Light option enabled:

In this example, all Corona Light Materials have the Emit Light option disabled. They are only visible directly and in the reflections:

 In this example, the outdoor lighting comes from a Corona sky object placed in the scene. The lamps on the wall were imported from the Chaos Cosmos library and are only using a translucent lampshade material with no illumination.

 Now, a Corona Light material is applied to the lamps on the wall, but the "Emit light" option is turned off (no light contribution at all). What seems to be a bit of lighting

,

is actually just the reflection of the lamps on the wall.

In this example, a Corona Light material is applied to the lamps on the wall, and the "Emit light" option is enabled (you can clearly see the light contribution on the wall, but also on the ceiling, chairs, and other objects). The resulting image has a little bit of noise.

Finally, a Corona Physical material using the Self-Illumination channel is assigned to the wall lamps (there is subtle light contribution), and the resulting noise level is higher compared to the other examples.

The Corona Light Material can be applied to Corona Decals. (Corona Physical Material with self-illumination can be used like this as well!)
In this example, Graffiti textures are being used as the emission texture of a Corona Light Material which is being projected by the Corona Decals.
