Lighting Products and Fixtures Design Waterlight Lamp by Jiahua Zhang, Nitesh Reddy N, Kejun Li Waterlight is a desktop lamp inspired by the water faucet. Turning the control bar up and down changes the brightness of the light. Turning the control bar from left to right adjusts the color temperature. Two potentiometers inside the sphere, one horizontal and one vertical, change the input voltage to create these effects. The light is produced by LED cells on a base. The head is made of bronze, the top lid of natural marble and the outer shell of glass. The bottom lid holds a circuit for wireless charging, so the lamp can be carried between rooms.
