How much can18w LED lighting lamps save for us?
Note: 1. The brightness of Greenough 18W LED lighting lamp is equal of 40W conventional fluorescent tube
2. According to the number of tube lamp for 1000
3. By lighting the lamp to work 20 hours a day, RMB1 per kilowatt computing
Three years full cost for ordinary fluorescent lamp is calculated as follows:
1. The three-year electric charge: 365 days * 20 hours * 0.045KW * 1000pcs* electricity RMB1 / kWh * 3 years = RMB985500.00
2. The three-year maintenance costs (required to replace the lamp, starter and other maintenance costs) RMB 5000.00.
3. The investment for 1000 pieces traditional lamps at RMB25/PC count: 1000 * RMB25= RMB25000.00
Total Investment: RMB985500.00+RMB5000.00+RMB25000.00=RMB1015500.00
Three years full cost for Greenough 18w led lamps is calculated as follows:
1.365 days * 20 hours * 0.012KW * 1000pcs * electricity RMB1/ kWh * 3 years = RMB262800.00
2. Do need to replace any of the materials, so maintenance is zero.
Each 18w LED tube by RMB158/PC calculation: 1000 * RMB158= RMB158,000.00
Total Investment: RMB262800.00+RMB158000.00=RMB420800.00
As can be seen from the above data, 18wLED lighting can recover the cost just need less than a year, savings of three years at a cost of RMB594700.00. Calculated as follows: RMB1015500.00-RMB420800.00=RMB594700.00
Moreover, each year 18wLED lighting lamps also saving more than about 70% calculated as follows: (328500-87600) / 328,500 = 73%
