The angled, straight and round versions of the ACO ShowerDrain E-line shower channels can be supplied with stylish green lighting. The ACO ShowerDrain Lightline LED module can be found in rainbow, blue or red. The control of the lighting is surprisingly simple. Once enough water has accumulated in the channel, the switching circuit connects to the contacts on the LED modules and the LEDs turn on. The lighting switches off again after a few minutes once no further water drains into the channel. In case the shower is used for fifteen minutes every day, the batteries will require recharging after approximately 90 days.
