I was a lighting consultant in a prior incarnation. I have 8 -75w recessed light over my sewing counter and around the room based on the task area. I have a fan with 3 lights for general light. and over my work counter (20feet long) I have 6- 18 inch flourescent undercounter lights with daylight bulbs. when my electrician was installing my lights and electrical requests, he wanted to know if i was going to be running a sweat shop!!
