Every time I switch back to my Layout workspace I get a flood of messages saying:

Too many lights in the scene !!!

Everything seems to be rendering fine. I do have some simulated "LED light arrays" in my scene. Is this a serious problem or should I ignore this? How many lights are too many?

  • @susu thanks i was mostly using Cycles to render but Eevee for VP-shading mode and I see that is what causes the warning. Thanks for pointing out the Eevee limitation in documentation, I guess it might be difficult to know which of the 128 are used or perhaps the first 128 it finds in the blend data. – james_t Jan 21 '21 at 21:42

    (I slightly enjoy the fact that some blender developer decided to use three exclamation marks for this warning. Almost as if using one ! is simply not enough here :)) – jachym michal Jan 21 '21 at 21:42

For questions like this please indicate what render engine you are using. Eevee has a limit of 128 lights in a scene.

Also, for simulated LED arrays you might want to consider a single texture as part of an emission shader.
