How much do Energy Star qualified CFLs cost?
CFL prices range from $4 to $15, depending on the style of bulb. Although a single CFL costs more initially, you actually save money, approximately $25-35 per bulb, in energy savings over the lifetime of the bulb, more than offsetting their initial cost. We recommend replacing the light bulbs in the fixtures you use most with ENERGY STAR qualified options, whether indoor or outdoor.
