Unlike most LED desk lamps, Mathmos does not deliberately sell its LED light source inside the outer glass. Instead, it uses a very traditional spherical bulb shape that changes color. The transparent glass cover and the old table lamp shape make the retro feeling very beautiful!
Place your hand on top of the lamp and press it to turn on the light. Press it again and it will be closed.
