Sunrise Simulation
Gradual brightening from 0% to 100% over 30-60 minutes. Starts with red/amber, builds to white.
Less stressful wake-up for fish than instant full brightness.
Thunderstorm Effect
Brief flashes of light simulating lightning, often triggered by random cloud cover.
Popular in premium fixtures like Aqua Illumination or Ecotech.
Moonlight Setting
Dim blue LEDs at 2-5% intensity. Some fixtures simulate moon phases.
Lets you observe nocturnal behaviors without stressing fish.
Cloud Cover
Random dimming across the day to simulate passing clouds.
Creates more natural dynamic lighting than static schedule.
