The delivery of the lamp went super fast. On the whole, it makes a good impression. But if like me you want to use to illuminate a nano aquarium lamp and these are allowed to run as usual via a timer which is pointless. Because after each switching operation of the switch always a different combination of the LEDs light up. That is if one day uses white LEDs for Bleuchtung, light the next morning after turning the blue LEDs. And one must first manually selected from the switch the desired light combination.
