Delta Faucet’s Tesla joystick lavatory faucet features the company’s Touch2O.xt technology, which activates the flow of water with a simple touch anywhere on the faucet and/or via intuitive hands-free proximity sensing when a hand moves close to the faucet. When paired with TempSense technology, an LED light at the base of the faucet changes from blue to magenta to red, visually indicating to the user the temperature of the water.
