Kelvin Edge is a minimalist design created by Italy-based designer Antonio Citterio. Kelvin LED is a table lamp fitted with Edge Lighting source. The lamp is available in white, black, chrome, and the new titanium finish. The optical switch mounted on the head of the lamp offers there-step dimmable control and a “green mode” for energy saving. By pushing the switch for over five seconds, the user can also select the color temperature they would like the LED to be.
