We planned our retirement home start to finish, and lighting was THE critical element for both my quilting room and Bill's workshop (he does miniature clipper ship modeling, woodworking and general tooling around). We selected 4' "day light" tube lighting - this is different from "full spectrum" in that I actually got sunburned using full spectrum lighting; we have "day lighting" inall our light fixtures; these 4' tubes cost about $4/$5 each at Home Depot.
Each of our workrooms has plenty of full southern exposure natural light coming in from one wall and each is just a few feet under 300 sq.ft., so we installed two ceiling mount units of two tubes each. There is NO cover of any sort over the tube lighting so as not to distort colors or strain my eyes; covers themselves discolor over time and thus distort the colors of my materials; patterned clear colors refracts light "oddly" and also influences color perception. It may not look sexy or "finished" but my eyes are sooooo happy when we work in these properly lit spaces.
For what it's worth, our selection was endorsed by several other professional (long arm) quilters who have the same installation. Of course, the number of tubes lighting your room will depend on total square footage AND the height of the celing - our ceilings are 10ft. for reference.
Whatever you do, DON'T GO CHEAP ON THE TYPE OF LIGHT (bulb) YOU BUY. Husbands typically like to "go cheap" on such things, but remember that it's YOUR space, YOUR craft and ... YOUR eyes. Buy what makes YOUR EYES happy and nothing else. Also, I have a small tabletop OTT light (~$80 usually, half-price at JoAnns with special coupons) that helps me more carefully gauge colors and, when focused on the sewing area of the machine, helps me finish projects during occasional late night sewing.
