Abstract
A reflective shade for an electric table lamp includes a conventional frustrum shape but with removeable translucent plastic disks spanning the top opening for reflecting the light back down toward the table top and for transmitting colored light for creating an ambiance in the environment. The disks attached to the shade are supported on a cylindrical chimney and the lower disk may fit within the chimney to center the shade on the lamp.
