Ben,
Thanks for the compliment!!! The fittings are made by Clipsal and yes they are screw fittings. The can adjust about 70 degrees to point it where you want and can be tightened to stay put. You can buy them from good lighting suppliers and cost about $18 each. I know an electrician who does all my stuff cheap for cash so I don't buy any of it personally. They are rated to take 200 watt globes, but not sure how they'd go with ceramics. Probably would be OK.
