Can You Make Me These Lights?

I asked the set dresser to make 50 large conical, how do you explain them? I know that little half circle lights that I could put my own bulbs in. In fact, I put 2K blonds inside the fixture and then put a little diffusion at the bottom. And there was like 50 of these in the ceiling. Because they were the most low angles. We had all these wide shots seeing the whole space with a huge crowd of immigrants and the lights at the top of the shot. So I wanted something quite graphic. It just varies so much and seems to seem project to project.
