Iray Ghost Light Prop Kit contains a collection of prefabricated light props with attached ghost lights to both boost illumination and resolve renders faster.

The array of props range from table lamps, floor lamps, handheld flashlights, and ceiling lights. Color and intensity presets allow you to change your lights on the fly.

Instead of retro-fitting already existing lights within your scene, you can simply drag and drop an appropriate IGLKP light into your scene and adjust them to your needs if necessary.
