Home IKEA HACKS Lighting A year ago I received a three legged lamp from Jason. Aurélien ups it a notch with 6 lamps. And yeah, it’s way cooler. The base uses a Blanda Blank with 6 Tertial lamps screwed onto its rim. The hard bit is the wiring and making sure everything lights up as it should. See more photos of the Tertial ceiling lamp.
