They look solid and well made. You're holding a giant 8-inch cob of corn horizontally. They don't seem to succumb to the weight of the bulb at all. The top of the ring contacts the bottom of the lamp to lock it in place, which works best with the cartridge I've seen. I bought two other ceramic versions of this and both have broken from the weight. Lightbulb (when installing a lightbulb).
