Compared to general-service incandescent lamps giving the same amount of visible light, fluorescents use one-fifth to one-third the electric power, and last eight to fifteen times longer. Fluorescents have 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. Fluorescent lamps contain mercury, which complicates their disposal. In many countries, governments have established recycling schemes for CFLs and glass generally.
