Thanks for taking an interest in the topic.
I share the images, family and parameters of the material.
In the images place the lamp with the active IES or without them and only with the led material.
The image "2022-07-23 Material Lamparas 10 Con material 130000 cd m2 y luz IES", is in my opinion the best. But in that image the LED material has 130000 cd/m2. If I turn off the IES you can see how the LEDs emit light and also participate in the illumination of the image. I don't know how much this affects the performance of the program, but I think two forms of lighting are duplicated with the same lamp.
In another file that I upload later, this duplication of lighting generated a problem in the video files.
It is not something serious.
What I see is that by raising the intensity of the material that it illuminates, so that the lamp looks more real, this lighting superposition is produced.
