The inner design high-tech water power device, no need for the battery, it will light up when the water flows! And it will light off immediately when the water stops, also the color of the LED will change with the water temperature changes.
It will light up to be green when the water temperature is less than 32 degree; Light up blue when the water temperature is between 33 and 41 degree. When the temperature is between 42 and 45 degree, it will light up to be red. When the temperature is higher than 46 degree, it will be red flashing, be careful that it's too hot!
You can tell the different temperature from the changing of the LED light color, therefore, it's no need to turn the turning frequently. Although there's no electricity, it will light up. It's a kind of Environmental product.
It won't lose any electric though it's waterpower. The DC current is only around 3.5V, the water flows and the wires system are separated.
We have two kinds of adaptors which are suitable for most of the faucets.
We applied the international Certificates for all of our products, including the CE, ROHS and so on, and we get the documents for all of these Certificates.
