Consumers now have three major types of bulbs to choose from: new and improved incandescents that use 28-percent-less energy, compact fluorescent lamps (CFLs), and light-emitting diodes (LEDs) that provide energy savings of at least 75 percent over incandescents and last a lot longer.
The luminous efficacy of a typical CFL is 50–70 lumens per watt (lm/W) and that of a typical incandescent lamp is 10–17 lm/W. Compared to a theoretical 100%-efficient lamp (680 lm/W), CFL lamps have lighting efficiency ranges of 7–10%, versus 1.5–2.5% for incandescents.
