1 Answer

Answer :

Role of replacement of old lamps by new more energy efficient lamps in the conservation of energy: i) Replacing incandescent lamps by Compact Fluorescent lamps: High wattage incandescent lamps are replaced by the low wattage CFL of same luminous output. ii) Replacing conventional Fluorescent lamps by energy efficient lamps: High wattage conventional fluorescent lamps are replaced by the energy efficient lamps of same luminous output. iii) Replacing Mercury/ Sodium Vapour lamps by Halide Lamps: High wattage Mercury/ Sodium Vapour lamps are replaced by the low wattage halide lamps of same luminous output. iv) Replacing incandescent lamps by Fluorescent Lamps: High wattage incandescent lamps are replaced by the low wattage fluorescent lamps of same luminous output. v) Replacing Filament/CFL lamps by LED: High wattage incandescent lamps/ CFL are replaced by the low wattage LED lamps of same luminous output. By these replacements, much more energy can be conserved.
