Take consider of the comparison of the light efficiency and the color rendering index we can find that: one piece of 1000W plasma lamp can equivalence to 2 pieces of 1000W metal halide lamp( no considering the light declining in ceramics metal halide lamp running ), and the lifetime of plasma lamp is 2 times to the metal halide lamp, so as a total by considering the lifetime and light efficiency indexes the one shot cost of metal halide is : 2×6500×2=26000YRMB, So we can find that the plasma lamp can save us 20500YRMB in the one shot cost.

根据两款灯发光效率和显色性的工程照明指标相比较得出：1个1000W的等离子灯相当与2个1000W金卤灯的照明效果（不计陶瓷金卤灯的后期光衰），而等离子灯的寿命是金卤灯的2倍，综合寿命和照明效果两项指标，在一次性投入上，金卤灯是2×6500×2=2.6 万元，由此可见，等离子灯的一次性投入比金卤灯节省2.05 万元。
