This page provides information on V-Ray IES Light. Photometric lights utilize an.ies file which contains the distribution profile for the light. An.ies file contains complete specifications of a real world light bulb or tube including the shape of the light cone and the steepness of the falloff of the light. Such files are usually provided by the manufacturer of the real-world bulb.
This page provides information on the types of V-Ray Lights.

V-Ray for SketchUp offers a number of lights essential for a good render. Whether you are preparing an interior or exterior scene, you can find the appropriate lighting options in the V-Ray toolbar or in the Asset Editor.
Depending on the scene and the effect you are trying to create with light, you might choose to use only one type of light or any combination of lights.
Below you can find detailed information on creation, application, and UI functionalities of the different V-Ray lights.UI Path: Asset Editor > Create Asset > Lights
Creating a light item from the Asset Editor does not create it automatically into the viewport. You can find the item in SketchUp's Components list and add it to the scene from there.
You can create lights in the Asset Editor from boththe Create Asset button (bottom-left corner) and the Lights category icon (top). If the Lights category is empty, left- or right-clicking on the icon prompts you to create a new asset. Otherwise, it selects the category, in which case right-clicking on it opens the creation menu.
The Asset creation dropdown lists remain active when Ctrl (Cmd on Mac OS) key is pressed, allowing the creation of multiple assets in quick succession. The Asset creation dropdown lists can be activated via the Create Asset button or the Asset Category icons.

When changing the Units of a given light, its preview is updated accordingly. Changes of the light intensity value are displayed to a certain amount in order for the preview to remain illustrative.
Selecting a V-Ray tool exposes hints about its usage in the SketchUp status bar.
Basic info is also displayed in the SketchUp Instructor Panel. It works for Infinite Plane, Scene Interaction Tools, and Lights - Omni, Rectangle, Spot, Sphere, and Dome.
Using the Esc key during light creation cancels the action without deselecting the tool.
Types of Lights
V-Ray Omni Light is a V-Ray specific light that can be used to create physically accurate lights. It casts rays in all directions from a single source. Find out more: Omni Light
V-Ray Rectangle Light is a planar light source with the shape of a rectangle or of a circular disk. Rectangle lights are useful for simulating man-made light sources, such as lamps, in an interior environment. Find out more: Rectangle Light
V-Ray Spot Light is a V-Ray specific light source plugin. Use it to create a physically accurate light that directs a narrow beam of light with falloff. Find out more: Spot Light
Dome (Area) Light
Dome light (also known as Area light) creates light within a dome or spherical shape to create a traditional global illumination setup. This light is frequently used to load HDRI environment images. Find out more:Dome Light
Sphere Light is a VRay Light object in the shape of a sphere, casting light outward in all directions. Find out more: Sphere Light
IES lights are designed to realistically simulate the distribution pattern of a light source by loading and using an IES (Illumination Engineering Society) file. An IES profile contains details about the behavior of the light, such as how the light passes through fresnel lenses, its intensity, and its falloff. Find out more: IES Light
Mesh Light can create light sources that have volume and shape defined by geometry in the scene without the need to use self illuminated objects and global illumination. Find out more: Mesh Light
Sun light is a spherical light source placed at a specific location which simulates the sun in the sky.There is no icon for Sun Light. It is automatically created in the scene and visible in the Lights section of the Asset Editor. Find out more: SunLight
V-Ray Light Gen
V-Ray Light Gen offers various lighting options. There are two main categories - Exterior and Interior. Find out more: V-Ray Light Gen
Scene Interaction Tool
Scene Interaction Tool shows the light intensity of a light object when you hover over it. To change the intensity, left-click and drag the mouse up or down to increase or decrease its amount. Find out more: Scene Interaction Tool

- When exporting a project from SketchUp to LayOut, you might want to hide the V-Ray objects (proxies, lights, fur, clipper, and infinite plane) exposed in the viewport. This is possible by using Hide V-Ray Widgets button in V-Ray toolbar.
- Negative intensity values are not allowed for any of the lights.
The context options of the Color Slot allow to Copy and Paste a color from one color slot to another, as well as to Reset the color selection to a default value.
You can reset the Input Number Slider's value to its default value by right-clicking on the slider and selecting the Reset context menu option.
- Most numeric V-Ray parameters come with a slider to make fine-tuning easier. Each slider is set to a default range of recommended or commonly used values. If a value above that range is used the slider adapts by increasing its range accordingly (2x the input value) to maintain usability. If a value below the current slider range is used, the slider again adjusts its range by shrinking it to twice the amount of the input value.
The slider range does not indicate the parameter's total minimum and maximum input values. The absolute minimum and maximum values of each parameter can be found by hovering over its spinbox.
The Select Objects in Scene option allows selection and multi-selection of components and groups in the viewport.
