Household electricity calculated using the 10 lights: (comparative data based on: an ordinary incandescent lamp by 15-20lm / w, ordinary energy-saving lamps by 30-60lm / w, LED lighting products by 120-150lm / w basis, this data is only done comparison reference purposes, slightly different in different parts of the market price.)
1, ordinary incandescent electricity:
10 × 60W / only × 5 hours / day × 365 days / year = 1095000W / h = 1095KWh
Year of electricity = 1095KWh × 1RMB/KWh = 1095RMB
2, the general energy-saving lamps of electricity:
10 × 15W / only × 5 hours / day × 365 days / year = 273735W / h = 274KWh
Year of electricity = 274KWh × 1RMB/KWh = 274RMB
3, LED energy-saving lamps of electricity:
10 x4w / only x5 hours / day x365 days / year = 73000w / h = 73KWh
Year of electricity = 73KWh × 1RMB/KWh = 73RMB
Annual savings of electricity relative to incandescent LED lamps: 1095RMB-73RMB = 1022RMB
Lamps into initial purchase cost:
1, ordinary incandescent: 10 × 1RMB / only = 10RMB, the average life of 2000 hours (about one year).
2, LED energy saving lamps: 10 × 55RMB / only = 550RMB, the average life of 30,000 hours (about 6 years).
Based on the above comparative analysis of the data input costs recoverable year:
LED lamps can be put into 550RMB-general energy-saving lamps 10RMB = 540RMB
Saving electricity 1022RMB / Year = 482RMB (surplus)
Taking a medium-sized supermarket stores electricity calculated using the 1000 Light: (comparative data based on: an ordinary incandescent lamp by 15-20lm / w, ordinary energy-saving lamps by 30-60lm / w, LED energy saving lamps by 120-150lm / w basis, this cross-referenced with the data only to do with, slightly different in different parts of the market price.)
1, ordinary incandescent electricity:
1000 × 60W / only × 12 hours / day × 365 days / year = 262800000W / h = 262800KWh
Year of electricity = 262800KWh × 1RMB/KWh = 262800RMB
2, the general energy-saving lamps of electricity:
1000 × 15W / only × 12 hours / day × 365 days / year = 65700000W / h = 65700KWh
Year of electricity = 65700KWh × 1RMB/KWh = 65700RMB
3, LED energy-saving lamps of electricity:
1000 x4w / only x12 hours / day x365 days / year = 17520000w / h = 17520KWh
Year of electricity = 17520KWh × 1 元 / KWh = 17520RMB
Annual savings of electricity is relatively common energy-saving LED lamps light: 65700RMB-17520RMB = 48180RMB
Lamps into initial purchase cost:
1, the general energy-saving lamps: 1000 × 20RMB / only = 20000RMB, the average life of 8000 hours (about 2 years).
2, LED energy saving lamps: 1000 × 55 Yuan / = 55000RMB, the average life of 30,000 hours (about 6 years).
Based on the above comparative analysis of the data input costs recoverable year:
LED light bulbs can be put into 55000RMB-P 20000RMB = 35000RMB-saving lights to save electricity 48180RMB / Year = 13180RMB (surplus)
