The documentation states that V-Ray Revit fully supports Revit lights, but it is unclear which parameters are supported.  
Support all of the following light shapes and distribution?  
or Only IES distribution ?

Also, do support all the lighting fixtures included in Revit?

Hi Yuji,

All 16 combinations for light shape and distribution are supported (4 of them include IES). Most of the family built-in [Photometric parameters](https://knowledge.autodesk.com/support/revit-products/learn-explore/caas/CloudHelp/cloudhelp/2019/ENU/Revit-DocumentPresent/files/GUID-D78A352A-4143-4D3E-8B0D-BB0991C6E0AF-htm.html) are also supported, excluding the Dimming Lamp Color Temperature Shift and the Light Loss Factor.  
And yes, all families of type Lighting Fixture are supported by V-Ray.

Best,  
Ana

The above relates only to native Revit lights.

A user just asked me in PM if they need to add a light source to Cosmos lights. The answer is “no”. Although being Revit families, Cosmos lights are a bit different, as they have a native V-Ray light embedded into them.

Hello, Ana

Thank you for the details. It was very helpful.  
My customer wanted to get a lighting analysis element in V-Ray Revit based on artificial lighting.  
I can explain to customers that V-Ray supports all Revit lighting.
