Total reduction for 10 years |
| Reducted Amount（B-A）＝ 3,120,750 yen |
| CO2 Reduction(D-C） ＝ 74t |
| Our LED light will save 3 million twelve thousand yen
（B-A), and save CO2 emission of 74 tons(D-C). |
※1 Expected life, 10 hours usage perday
※2 Electric cost is calculated with 15 yen/kwh
※3 The carbon dioxide emission is calculated based on exhaust coefficient (0.357kg/kwh) by NEDO
※ By saving the energy, Basic Electric Bill will also be reduced. |
