Note: The average life of traditional halogen lamps and metal halide lamps is 8,000 hours. It is calculated by using 15 hours per day and about one and a half years. LED lamps have an average life of 30,000 to 50,000 hours and can be used for 5-10 years without maintenance within 3 years.
Remarks: Calculated by 30 days per month, the gray bottom is manually input by the user.
formula:
Total monthly electricity consumption = time * quantity * power * 30 / 1000
Monthly total electricity fee = total monthly electricity consumption * electricity price
Saving rate = saving electricity bills / fluorescent tube monthly total electricity bill
Cost recovery time = initial investment cost difference / saving electricity bill
One-year investment profit = one year savings in electricity costs - initial investment cost difference
Two-year investment profit = one year investment profit + one year saving electricity fee + maintenance cost
Three-year investment profit = two-year investment profit + one year savings in electricity costs + maintenance costs
