Lated with an Excel sheet, as shown in Table five. In Table five, A = 1, B = 346.86, and C = 30,121.742. The discounted payback period is calculated employing Equation (7) and is equal to 1.01 years. As a consequence of fluctuating oil Ciprofloxacin D8 hydrochloride Biological Activity prices and as the availability and value of LED lamps varies from location to spot, the authors performed a sensitivity analysis with varied prices of electrical Mifamurtide Description energy and LED lamp expense to check the financial feasibility of replacing HPS lamps with LED lamps.

In regions where the electrical energy prices are low, it really is nevertheless economically viable to replace the energy-inefficient HPS lamps with LED lamps, even using the higher investment price of LED lamps. Having a low electricity price tag of 0.05 /kWh and higher price of LED lamp ( 200 per lamp), the discounted payback was only 3 years, which proves the financial feasibility in addition to the reduction of tonnes of CO2 emissions. five.
