Thank you, all, for your input. I decided to go with halogen track lights. They were installed in my new sewing room this morning. I've worked under them all day today, and so far they've not felt too hot. The light is terrific, and my quilts look very different. I've been quilting in the dining room, which is yellow with an orange accent wall. The walls in my sewing room are a light gray. Now I have to get the rest of the room set up, and my quilting frame comes in the middle of August. Can't wait!!
