I meant like if the photoperiod is off and you wanted to turn it on just for a second to check something out and vice versa. Or turn it off for some reason in the middle of the photoperiod with the click of a button.I am not sure what you mean by turn the light on and off. I would just power it on and off with a controller if you want that, but I leave mine on all the time and turn colors/segments off using the photoperiod schedule. Anywhere a section is dragged to 0% it is off.
You can customize any of the presets and save them as something new.
