2D Light node draw a light on top of original surface. If you want the light to cast a shadow, check out Cast Shadow.

Light Properties

Light Shape

Control the shape of the light. There are 4 available shapes: Point, line, line asymmetric, and spot.

Range

The size of the light.

Intensity

The brightness of the light. Adjusting this amount may effect the resulting range.

Color

Control color of the light. Note that light use additive blending.

Attenuation

Control the falloff of the light. There are 3 available falloff: quadratic, invert quadratic and linear.

Banding

Banding convert smooth light to discrete steps. The banding width depends on the Attenuation.

Radial Properties

With point light, you can use Radial Banding to add the "shine" effect to the light.

Radial Banding

The amount of radials, set to 0 for a full circle.

Radial Start

Rotate the radial effect.

Radial Band Ratio

The width of the radial band as a ratio. 0 means no light and 1 mean fulll circle.
