I have no idea if this high, low or somewhere in between. Personally, I would like more info on what the power setting range is. With respect, this tutorial only shows how to ‘build’ the example shown. I hate to be critical of anyone who makes the time and effort to educate those of us who are less knowledgeable on a product, but this tutorial could be a lot more helpful.

A simple box with 3 pin lights as shown in the image below.

Another collection of IES files can be found in the links below: Included is a complete database of IES files for current GE products. Its a powerful lighting design aid for GE directional reflector lamps. More IES files here if those don’t work for your particular version of V-Ray.You can also download the GE Light*Beams 3.0 software at the bottom of this page. You can download IES files files of your own choice from here GE Lighting and more here IES Maps and a SketchUp light fitting here. In this simple tutorial we are going to set up three basic pin lights using imported IES files. I have a new second tutorial, just published called Basic IES Light Tutorial using V-Ray for SketchUp. I use V-Ray release version 1.48.90 in it, which is a much better and stable release.

Lamp manufacturers create these files for accurately simulating their lights and now we have the ability to add IES profiles (for light accuracy). IES (Illumination Engineering Society) is a standard digital file in ASCII format, which measures the distribution of light, in other words the intensity of the light and its shape. V-Ray works within the SketchUp environment allowing users to be able to efficiently incorporate the task of rendering within their current workflow. 1.48.66) has the new added feature of IES Lights and Spotlights.
