How to save 840,000 electricity bills for led fluorescent lamps?
Take the traditional 40w fluorescent lamp that is currently widely used as an example
1. Power consumption analysis:
1. The actual use power of a conventional 1.2m, 40W fluorescent tube is 45W (including the power of the ballast).
Assumption: The lamp is used for 12 hours a day, and the use time is 365 days per year. Then the power consumption of each fluorescent lamp in 1 year is:
Annual power consumption (Pt)=40W*12H*365≈175 kWh
2. LED fluorescent tube: 18W (instead of 40W fluorescent lamp)
The annual power consumption is:
Annual power consumption (Pt’)=18W*12H*365≈78 kWh
Assuming that the electricity fee per kilowatt-hour is x=1.00 yuan, the annual electricity fee that can be saved is X:
X=x*(Pt—Pt’)=1*(175-78)=97.00 yuan
3. According to the use of 1000 LED fluorescent lamps, LED fluorescent lamps will save more than conventional fluorescent lamps every year
97*1000=97,000.00 yuan.
2. Comparison of economic benefits: (conservative estimate, used for 5 years)
A. LED fluorescent lamp:
1. The cost of lamps and lanterns, calculated by 1000: 1000*60.00=60,000.00 yuan
2. Cost recovery time: 60,000/97,000=0.6 years or 7 months
3. Benefit: 5-0.6=4.4 years
4.4*97,000.00=426,800.00 yuan
That is to recover the cost in 7 months, you can also earn 426800.00 yuan in electricity bills
In fact, it is a profitable product that kills two birds with one stone.
