This LED shower head automatically changes colour depending on shower length to make you aware of how long you have been showering. This shower head also has an integrated flow restrictor disc to limit the water flow rate to 10 l/min. You not only save water but also cut your energy costs.
Integrated LED colour changes:
Up to 3 minutes: the LEDs glow green (approx. 30 l total water consumption)
3 to 5 minutes: the LEDs glow orange (approx. 50 l total water consumption)
5 to 6 minutes: the LEDs glow red (approx. 60 l total water consumption)
6 minutes or longer: the LEDs blink red (water consumption of over 60 l)
