Because of the Apex integration with Radions, it's pretty easy to do this.
First, you go to the Profiles page, create a new Profile, name it, and make it of Type Radion.
Then enter your spectral parameters. Make the start and end intensities the same, with 0 ramp time.
Then, from the Outputs page, select one of the Radions and click on it.
That will bring up the scheduling wizard.
Click on the box at upper left that says Basic View.
Then under Control Type, select Advanced.
At the end of the programming you'll now see on the right, add:
If Feedx 000 Then NewProfileName
and upload. Repeat for each light.
Now, when you turn on the specific feed mode, the lights will go to the custom setting.
Turn off the Feed mode, and the lights revert to your normal programming.
It's also possible to do this without using Feed mode, but rather by creating custom switching virtual outputs.
This is what I prefer, because I can set up multiple custom lighting situations and also name them appropriately.
1. First, you go to the Profiles page, create a new Profile and make it of Type Radion.
Then enter your spectral parameters. Make the start and end intensities the same, with 0 ramp time.
2. Next, create a Virtual Output from the Outputs page and name it something descriptive.
It'll just be used as an on/off switch on your dashboard, so no programming besides Set OFF.
Move the new tile from the hidden Tiles area to your dashboard.
3. Finally, from the Outputs page, select one of the Radions and click on it.
That will bring up the scheduling wizard.
Click on the box at upper left that says Basic View.
Then under Control Type, select Advanced.
At the end of the programming you'll now see on the right, add:
If Output NewVOName = ON Then NewProfileName
and upload. Repeat for each light.
Like this:
Now when you turn an output to ON, the lighting changes to your custom settings.
When you switch it to OFF, lights revert back to the schedule.
