It's OK... Thanks!
Very nice looking aquarium lamp. Came very quickly as the depot is located in Czech Republic. Everything is as described and looks well manufactured. When connected together and set up in the app everything worked perfectly. The only small negative is regarding the control app. It is general smart home app and seting up the smooth lightning curve will take a lot of effort. It is like drawing the curve point by point, the dedicated aquarium controllers offer better interface but for much higher price so this is up to you to choose a solution for you, for me it is ok. I will add photos once I install it on the tank.
I have installed the light on my tank. The result is very nice. This is not at full power, the photo is taken on settings: brightness 70, color temp. 55. The only limitation for me are the power supply cables. The length is not enough for my tank set up. The light is 140cm above the electrical compartment, so if you have similar setting, get longer cables right away. Beside that, it is a great light.
