Image: A detailed view of the inline controller, highlighting the functions of each button: Power (on/off, switch modes), W/D (adjust white LED brightness, daylight timer), B/N (adjust blue LED brightness, moonlight timer), and Timer (set timing combinations).
- Power Button (⏻): Press to turn the light ON or OFF. Long press to switch between daylight and moonlight modes.
- W/D Button (White/Daylight): Adjusts the brightness of the white LEDs. Also used to set the daylight timer. There are 6 levels of brightness.
- B/N Button (Blue/Night): Adjusts the brightness of the blue LEDs. Also used to set the moonlight timer. There are 6 levels of brightness.
- Timer Button (◷): Cycles through preset timer modes (e.g., 8H, 10H, 12H). These modes simulate natural light cycles, including a gradient effect for sunrise and sunset.
Gradient Effect
The SlimLED light can simulate natural sunrise and sunset effects, gradually increasing and decreasing light intensity to create a realistic and comfortable environment for your aquatic inhabitants.
