Nothing particularly special, but I like buying cheap all-metal $5 lamp bases and repainting them. Because holy shit are lamps expensive.
My favorite so far has a multi-spiral body with a leaf-shaped light diffuser under the bulb, which I painted with chameleon paints, so depending on the time of day/color of light it’s a variety of different colors (mostly purples, blues, and greens). It lives in my very bright living room for optimal effect.
