The Cone of Shame, in animal lamp form. 19 bright and pop-y plastics to choose from (choose PBR with fallback or non PBR for each option), touch on and off. Mirrored version included so you have both sides to face any direction you need. There is a projector light on the basic version- it's a separate prim linked in there (sort of hard to find, made as little as possible to keep it out of the way!)- that casts the circular light out of the shade, and there's a soft glow on the lamp itself. The (no cast light) versions do not have those light sources, so they will not conflict with your lighting scheme, but will light up the bulb and glow the shade.
You can find this and more in world at the elephant.
