I've just realized that I have florescent in the master bathroom, the small dining room (banded by dark wood) and in the middle office. The front bedroom has a big modern twisted bulb that surprised me with the amount of light it produces. I can see quite well when sewing, on the computer or reading. The "daylight" ones are nice and make the colors real instead of dull and drab. Shows up white balls of cat hair too, way too easily.
