【Remark】

  • Lamp quantity: actual in use lamp.
  • Usage time:Please enter the actual use hours in one day.
  • Usage days:Please enter the actual use days in one year.
  • Service power: If traditional lighting use ballast,Please put the ballast power into account.
  • Electricity unit price=21JPY/KWH One year electric charge=one day use hours*one year use days*electricity unit price*power/1000
  • *CO2 emission coefficient:0.43kg-CO2/KWH
  • CO2 emission coefficient is according to Japan Ministry of the Environment on 25th,March 2011
