4 LEVELS BRIGHTNESS &NIGHT MODE- Whether you prefer a gentle glow or a brighter light, easily customize your environment to suit your mood and needs. Our thoughtful night mode (default night mode period: 7:00 pm–7:00 am) ensures you enjoy a restful sleep without the hassle of constant adjustments. At night, it automatically dims the display to a soft light that won't disturb your sleep. In the morning, it automatically turns on a bright white light so you can check the time.
