Button Functions:
- W Button (White LEDs): Press to adjust the brightness of the white LEDs. Multiple presses will cycle through different brightness levels.
- B Button (Blue LEDs): Press to adjust the brightness of the blue LEDs. Multiple presses will cycle through different brightness levels.
- Timer Button: Press to cycle through the built-in timer options (8 hours, 10 hours, 12 hours). The light will automatically turn on and off at the set intervals.
- M Button (Mode/Power): Press to switch between daylight mode (white and blue LEDs) and moonlight mode (blue LEDs only). Press and hold for 3 seconds to turn the light ON/OFF.
Color Temperature Adjustment:
The independent control of white and blue LEDs allows for precise color temperature adjustment. You can lower blue lights for a warmer appearance or increase blue lights for a cooler, more intense look. This feature is useful for highlighting specific fish colors or plant growth.

Sunrise/Sunset Simulation:
The integrated timer includes a 15-minute ramp-up and dim-down feature. This gradual lighting increase and decrease simulates natural sunrise and sunset conditions, preventing sudden changes that can startle fish and providing a more natural environment.

Maintenance
- Cleaning: Regularly wipe the light fixture with a soft, damp cloth to remove dust, water spots, and algae buildup. Ensure the light is unplugged before cleaning. Do not use abrasive cleaners or solvents.
- Inspection: Periodically inspect the power cord, controller, and light fixture for any signs of damage or wear. Replace any damaged components immediately.
- Heat Dissipation: Ensure the aluminum alloy housing remains clear of obstructions to allow for proper heat rejection, which is crucial for the light's performance and lifespan.
