Sphere light settings are grouped into basic and advanced settings tabs.

– Basic settings tab.

– Advanced settings tab.

An * next to a parameter name indicates that the parameter value has been modified.

Enabled – Turns on and off the sphere light.

Color – Changes the color of the sphere light.

Intensity – Specifies the intensity of the light's brightness. 

Invisible – When enabled, makes the light invisible, both to the camera and to reflections. This is useful to prevent bright speckles on glossy surfaces where a ray with low probability hits the extremely bright sphere.

Radius – Specifies the radius of the sphere light.

Shadows – When enabled (the default), the light casts shadows. Turn this option off to disable shadow casting for the light. The value moves the shadow toward or away from the shadow-casting object(s). Higher values move the shadow toward the object(s), while lower values move it away. If this value is too extreme, shadows can "leak" through places they shouldn't or "detach" from an object. Other effects from extreme values include Moire patterns, out-of-place dark areas on surfaces, and shadows not appearing at all in the rendering.

Affect diffuse – Determines whether the light affects the diffuse portion of the materials. The value controls the light's contribution to the diffuse portion of the materials.

Affect specular – Determines whether the light affects the specular portion of the materials. The value controls the light's contribution to specular reflections.

Affect reflections – Specifies whether the light source appears in reflections.

Use global mult. – When enabled, uses the Enable Lights value (Render tab > Advanced mode > Lighting rollout) as a multiplier to Intensity value. When disabled, the light is independent from the global multiplier.
