LED based bath lights to check tub temperatures
You no longer may need to dip your toe or get your fingers burnt or frozen, to check the temperature of your bath water. Although currently in a conceptual stage, designer Kai Chan has come up with a LED-based Bath Light which changes colors based on the temperature of the water. The device can also be used just as a simple bath light or a candle (in which the LED flickers softly).
