1) The 400W Metal Halide Electronic Ballast, its power consumption is about 28W, according to the above formula, a three-year run electricity to 0.7 RMB × (10H x 340D x 3Y × 0.428KW,) = $ 3055.92.
400W Metal Halide Electronic Ballast average price of $ 260, 400W metal halide electronic ballasts early failure rate of about 2%, equivalent to the average price of each electronic ballast 260 × 1.02 = 265.2
400W metal halide electronic ballast lighting system for three years running cost of 3055.92 RMB +265.2 = 3321.12 RMB.
2) Energy-efficient European standard 400W Metal Halide Ballast own power consumption of about 28W, according to the same formula electricity to run for three years was 0.7 × (10H x 340D x 3Y 0.428KW) = 3055.92, energy-saving the European standard 400W metal halide magnetic ballasts an average price of 145 RMB, early failure rate of 0.01%, equivalent to 400W each European standard magnetic ballast average price of 145 × 1.0001 = 145.02 RMB.
Magnetic ballasts have a useful life of more than 10 years, three years running depreciation expenses 145.02 RMB × 0.3 = $ 43.50.
Trigger price of $ 16, the compensation capacitor 43μF, price $ 40, set two parts the average life of three years, three years of operating costs for a total of 43.50 RMB +16 +40 = 99.50 RMB.
Energy-efficient European standard 400W metal halide magnetic ballasts lighting system for three years running costs of 3055.92 RMB +99.50 = 3155.42 RMB.
3)For better quality American standard 400W metal halide magnetic ballasts, due to the internal the local magnetic circuit saturation, so the power consumption of about 58W, also according to the above formula, three years of electricity to run 0.7 $ x (10 hours × 340 days × 3 × 0.458KW) = 3270.12.
400W Metal Halide Ballast ANSI average price of 220 RMB, early failure rate of 0.02%, equivalent to the average price of each 400W American standard metal halide ballast $ 220 × 1.0002 = 220.044 for 10 years life of magnetic ballasts, three-year depreciation expense of 220.044 RMB × 0.3 = $ 66.01, series capacitor 36μF, the price is 36 RMB, so the running costs of three years a total of 3270.12 RMB +66.01 +36 = 3372.13 million.
Since the the basic 400W metal halide lamps are used outdoors, self-heating caused by the air conditioning so there is no additional charge.
From the cost analysis of the three-year run, 400W Metal Halide run systems, energy-efficient European standard metal halide lighting system operating costs have been significantly lower than the operating costs of the metal halide ballasts and American standard metal halide The lights running costs of the system slightly higher than the electronic ballast operating system.
