Good job on the scene!

One suggestion: In a real LED, the entire body of the LED glows rather than just the semiconductor material, as shown in the scene. So, in order to make it look more realistic, I suggest that you make the entire body of the LED glow the same colors as the semiconductor.

I mean it's really hard to do that because I tried that in this scene and it dimmed the color to where you could barely see any color.

There are ways to do it so that it doesn't dim the other colors, but it may require some scripting. I could show you an example of how to do it, but I just don't have time right now. I have too many jobs around the house that I have to take care of.

For a long bright laser beam path set colorHSVA = [0.0, 1.0, 10.0, 1.0]
