Energy saving lamps
Compact fluorescent lamp (CFL) or Energy saving lamps give the same amount of visible light as general-service incandescent lamps.
CFLs use one-fifth to one-third the electric power, and last eight to fifteen times longer. A CFL has a higher purchase price than an incandescent lamp, but can save over five times its purchase price in electricity costs over the lamp's lifetime.
Different types and models are available, according to the regulations of the country of destination.
