Verify Lighting: Check Your Plan for Errors

After you've laid out a lighting plan using our Lighting Manager, you can use our Verify tool to check your plan for errors.

How to Error Check Your Lighting Plan Using Our Verify Wiring Tool

Open our Lighting tool:



F/X Site ribbon, Lighting flyout


F/X Site ribbon, Lighting flyout

F/X Site menu


F/X Site menu, Lighting option




GRAPHICS toolbar

Verify Wiring, overview of possible errors

Our Verify Wiring tool will scan your lighting design for the following errors:

  • Errant wire fittings or callouts
  • Unwired fixtures
  • Wire routing (invalid electrical paths)
  • Overvoltage and undervoltage
  • Overcurrent


The tool will delete any errant wire fittings and callouts. Any detected errors will have a red "X" and a highlight button next to the corresponding entry in the Verify Wiring dialog box. You can click this button to highlight the problematic fixtures in the listed color.


In our example, the tool has detected fixtures that are not connected to a power source. To see which fixtures the error applies to, click the Highlight button. The unwired fixtures will be highlighted (in this case, in green), allowing you to make corrections as needed.




Keep clicking Verify after making changes until you see a green check mark next to each error type, indicating that your design is free of lighting errors.

Error: 'Bad argument type: Numberp nil'

Are you seeing this message when running Verify Lighting? If so, Make sure you don't have any looped wire sections in your wire paths to fixtures.

Verify Lighting and Generic or Custom Fixtures

When configuring a generic or custom light fixture, take care to input the voltage minimum and maximum in the following format: minV|maxV (where min is the fixture's minimum voltage and max is its maximum voltage – example: 10V|15V).


Failure to use this format will result in an errant voltage message and calculation, and will prevent our Verify tool from running properly on these fixtures.
