The parameters are simple and easy to tune and the light follows the shape's render visibility as opposed to selections on the light.

Warning

While you may use a meshlight as a deforming piece of geometry, deformation motion blur is not yet supported and could provide incorrect results.

Exposure

Specifies the exposure of the area light as a power of 2. Increasing the exposure by 1 will double the energy emitted by the light source. A value of 0 produces an intensity of 1 at the source, -1 produces 0.5. R eal world lighting has high energies and typical exposures are low values while you may have to type a really large number for equivalent Intensity. This is also comfortable to artists familiar with photographic measurements.

Texture Color

An image to use as a light source using a pattern node, e.g. PxrTexture. Preferably a High Dynamic Range source. Notice this affects color and shadowing based on the contents of the HDRI used. If forced to use an 8-bit source such as a JPEG image, it should be linearized (transformed to linear color space) before use as a color. Since this is indeed a mesh, you must have defined UVs or appropriate projections to place your texture correctly.

Temperature

Allow the user to choose the color temperature of the light in Kelvins. Unlike the basic light color, this allows the user to easily pick plausible light colors based on standard temperature measurements.This control will act like a filter or gel (a tinted transparent surface) in front of your light. If your light is white, you will get the chosen color temperature. If your light is colored, the color temperature will make it cooler (over 6500K) or warmer (below 6500K).

...

Info

The effect will be less pronounced on fully saturated mono-chromatic lights. Defaults to 6500K, which should be very close to white on most monitors (D65 illuminant used by sRGB and Rec 709).

Specular Amount

Amount of specular light that is emitted. This is a non-physical control. You could use a light with  Specular Amount  0.0 to act purely as a source of diffuse light for your scene objects and avoid adding highlights. 

 

Diffuse Amount

Amount of diffuse light that is emitted. This is a non-physical control. You could use a light with  Diffuse Amount  0.0 to act purely as a source of highlights for your scene objects.
