You can ramp up-down the leds at any power level 0-100% at anytime you input. Example: You want to go from 0-50% in 3hrs,or 0-58% in 38minutes,it's 100% customizable to your needs.
The Optics are custom made for me.The inside uses 70/120 and the outside uses 90/120 dual spread optic lens in one casing.
