Moen's pull-down kitchen faucet featuring ColorCue® technology integrates LED sensors on the pulldown wand. The faucet's pull-down wand seamlessly integrates an aesthetically pleasing ribbon of LED light that is visible from all angles and changes colors based on the temperature of the water streaming through the spout for safety and convenience. The light display allows you to know exactly when the temperature is just right for any kitchen task, eliminating the need to test the temperature with your hand and risk potential scalding or discomfort caused by water that is too hot or too cold.
