Today, improvements in fluorescent tube lighting make it nearly indistinguishable from incandescent lights in quality, color, and its ability to create a warm-light atmosphere. Look for lamps with high-color-rendering indexes. They may cost a little more, but produce a warmer, more pleasant light. New electronic ballasts totally eliminate the irritating hum and unpleasant flicker associated with older fluorescents and can reduce energy use by 35%. These newer tube fluorescent lights work well as indirect lighting around a room perimeter or a bathroom mirror. They also fit in most any fixture these days. The new spiral designs will fit in almost any table lamp, recessed, or even decorative fixture.
