This lamp brought a lot of humor to our house. Since the instructions are the new-normal vague and there's no obvious on/off switch, it took a while to figure out how to turn it on. Finally we realized it was just a little pinch to any one of the posts. At least for me. My husband tried and tried to no avail. He tried warming his hands, touching light, touching hard and no light. I'd go over, touch and there was light. I greatly enjoyed the three days before he finally mastered the technique. We actually love the lamp, but I miss tormenting him with my super power.
