6.1 Setting Local Time

Before programming any light cycles, set the current local time on the control panel. Refer to the video below for a visual guide on how to set the local time.

6.2 Standard Mode (Daylight & Moonlight Cycle)

The default auto cycle simulates a natural 24-hour light cycle with gradual sunrise, midday, sunset, and night phases. The white daylight mode combines white, red, green, and blue LEDs for bright illumination. The moonlight mode offers 6 single-colored options (red, purple, blue, cyan, green, yellow) and 10 dimmable levels.
