It is improved by 150%. It is because our PSJ Technology we use is not reduce voltage. Our technology is “Non-Critical Intersection” which basically the input to the system is 220 (+/-)Volt , but if you measure each lamps required holding voltage of 105 Volt (Fluorescent). And 115 Volt is dropped in ballast. With our technology will use micro processor to manage the unnecessary areas or Non – critical area which lost in ballast. Therefore, the heat of ballast will be reduced which affects the working temperature of lamps.
