(eevee) Lights limit? My question is...

How many lights (spot) can be on at the same time?

There's a limit imposed by blender or the machine specs?

Here's an example https://youtu.be/8Hjy2o3A9pg
Limitations:


Shadows are not supported on light instances (dupli objects, group
instancing).
Only 128 active lights can be supported by Eevee in a scene.
Only 8 Shadowed sun lights can be supported at the same time.
