[solved] Most efficient way to get sum of all light states?

[buuuudzik]

But event scripts can be not a good solution when there is some change of whole room or much more when there is whole floor change. Then there are a lot of unnecessary serial calculations of every event. With this resident script you can also prepare some layers and I use also such solutions.

More on this forum about this task(more about OR calculations but also universal):
