In e.g. a table lamp, base (20) and shade (30), like the former (12), are typically plastic injection moldings. Opt., the base is of wood, or of crust or fabricated metal, and/or the shade translucent sheet on a conventional frame. The former, clipped (22,23) to a ballast weight (21) in the base, is a flat vertical plate, fixed at the top to the lamp-socket holder (42), with grip-holes for the flexible lead (43) and an outer edge (13) of T-section, grooved (14) on each side to accept the edges of a translucent plastic sheet, covered if desired with decorative fabric.- DETAILED DESCRIPTION - The sheet is cut so as to roll into a conical or cylindrical column whose lower end is pushed into a correspondingly shaped retaining funnel on the base top. Light entering the column at the top is diffused by the rolled sheet, producing a luminous effect.Where the sheet is rolled into a cylinder, the light source is opt.placed just above the base to give the effect of a luminous pillar
