It helps that the light has two lighting modes for easier transitioning from daylight to night mode. During the day, blue and white LEDs will shine on the tank while the night mode only features the blue LEDs. The light is compatible with a dual channel timer from Nicrew (sold separately), so you can use the timer to transition between the lighting modes gradually.

Even better, the lighting mimics real-world situations using additional lighting modes. Using the wired remote, you can choose from various modes, including three fade modes for cloud cover effect, two lunar modes, two storms with lightning effects, and a dusk mode for evening viewing.
