Just a few more cents worth. Remember the mini light booths in box stores for picking paint chips? They would usually have three different colour temps (in those days fluorescent). The idea being to put your paint samples under the light that would be in use in the room the paint was destined for so that you could see what it would look like in that light.
I would think most (Not all) quilts are going in bedrooms and living rooms and family rooms. If you prefer warmer temperatures in those rooms you might want to do the same in your sewing room. Or pick a happy medium. Or pick up a product in the line of what Tartan described and have as much flexibility as possible.
