That doesn’t seem like much control on the sunrise/sunset transition. That would only be 90 sec total from 10% to full 100%. A minute and a half. To be honest I’m not sure the plants give a damn lol. I have never seen any detrimental effects of my lights coming on full blast even back when I was using Metal Halide and Sodium, of course those DO come on slowly all by themselves warming up.
Would have been nice if they would have offered at least a 15 min. transition from dark to full. I believe the dimming control varies the output from the driver to the LED’s. But to be honest I have never fiddled with LED controls or drivers. I believe the LED’s have to have the capability to be dimmed from what I read @PreyBird1 ? and not all have that.
