The Twinstar Lighting Controller allows you to automate your aquarium lighting with ease. It simulates gentle sunrise and sunset transitions, creating a natural light environment that supports plant growth and reduces stress in fish. Operation is simple and intuitive using three physical buttons on the deviceno app or external programming required. You can set custom on/off times, with a smooth 10-minute fade-in and fade-out. The controller is compatible with most Twinstar LED lights as well as other LED systems operating at 12-24V DC (up to 5A). Installation is quick and straightforward via plug-and-play between the power supply and the light fixture.Twinstar Lighting Controller+ gentle 10-minute sunrise and sunset simulation+ adjustable on/off timer settings+ provides 7 levels of brightness adjustment+ ON/OFF button to turn on or off at any time+ easy control via three onboard buttons (no app required)+ compatible with 12-24V DC LED systems (max. 5A)+ simple plug-and-play insta
