Fourth-Stage Dimming Explain
The Fourth-Stage Dimming is core feature of SM-0A5.
In most case,We want more energy-saving at mid-night or late-night,because there are no one. The Controller provide Fourth-Stage light mode,every stage brightness of LED and timer can be set by IR Parameters Setting Device [SM-IR08]. Default the First-Stage brightness is 100%, Second-Stage brightness is 50%, Third-Stage brightness is 30%.Fourth-Stage brightness is 50%.By using Foruth-Stage Dimming you can reduce power consumption up to 50%!
Other note :The Fourth-Stage is Early-Morning Light .
